How Much Does Trade Surveillance Software Cost in 2026?
A custom trade surveillance layer costs $110,000 to $850,000 depending on how much of the detection and case estate you own rather than rent. The decision that moves the number most is the count of distinct order sources you have to normalise.

A custom trade surveillance layer costs $110,000 to $850,000 depending on how much of the detection and case estate you own rather than rent. The decision that moves the number most is the count of distinct order sources you have to normalise. One order management system with a single drop copy keeps you near the bottom of the first band. Three order management platforms plus a vendor algorithm container plus five venue feeds is five ingestion projects rather than one, and in our delivery experience each additional source dialect adds roughly $25,000 to $50,000 before a single scenario is written.
The bands a trade surveillance build falls into
A focused first release covering normalised order and execution capture, replayable lifecycle reconstruction, two or three firm specific scenarios and a proper case workflow runs $110,000 to $240,000 and ships in 16 to 22 weeks in our delivery experience. A full platform adding cross venue and cross product detection, identity resolution across legal entities, trader behaviour baselining, alert scoring, linkage to communications surveillance and regulator ready case export runs $300,000 to $850,000 phased over 10 to 18 months.
Notice what is not in either band: a detection library. Reproducing the scenario coverage that Nasdaq SMARTS, NICE Actimize, Eventus Validus, SteelEye or Behavox already ship is the most expensive and least differentiated thing you could spend this budget on. The bands above assume you keep a vendor for breadth and build the layer underneath it that makes the alerts mean something.
The first band is drawn around one deliverable: an analyst can select a five minute window and watch what actually happened, with parent and child order linkage intact and venue timestamps at their native precision. Everything else in surveillance either depends on that or is cosmetic.
What drives a trade surveillance build up
Order source count is the primary driver. Each order management system, each algorithm container and each venue drop copy speaks its own dialect of the same event, and normalising a dialect means reading a message dictionary, handling the fields that were never populated in your configuration, and reconciling amend and cancel semantics that differ between systems. A firm running three platforms is not three times the work of one, but it is meaningfully more than one and a half.
Asset class breadth is the second. Equities and listed derivatives have a clean order lifecycle that a system can reconstruct. Fixed income and over the counter derivatives frequently do not, because negotiation happens on a chat or a voice line and the electronic record starts at the trade. Extending a build into those products is a data sourcing problem before it is a detection problem, and it should be quoted as one.
Historical replay depth is the third and it is chronically underestimated. Retention alone is a storage purchase. The requirement that actually costs money is querying a five minute window from two years ago in seconds, at full message fidelity, without a batch job. That is a partitioning, indexing and storage tier decision that has to be made at design time. Retrofitting it later is close to a rebuild, which is why we insist on settling it in week one.
Identity and instrument resolution is the fourth. If the same beneficial owner appears as two participants because two of your entities route through different memberships, cross venue detection is impossible until that is fixed. The same applies to an instrument graph that knows which option references which underlying. Neither is glamorous, both are prerequisites, and packaged tools expect you to supply them.
Regulatory reporting adjacency is the fifth. Consolidated audit trail linkage and similar obligations share your order data but have their own timelines, formats and validation regimes. Treat them as a related project with a separate budget rather than a feature.
What keeps the number down
Picking two or three scenarios where your business genuinely carries risk is the largest saving available. A firm whose exposure is spoofing on a single liquid venue and wash activity between two internal accounts does not need forty scenarios. It needs two that are correct and defensible, plus the vendor library it already pays for.
Starting with one asset class holds the number down more than anything else in the design. Equities first, then listed options once the instrument graph exists, is a sequence that keeps each phase provable.
Keeping the vendor for coverage breadth cuts scope substantially. The build then reads vendor alerts as one more input into your case workflow alongside your own scenarios, which means you get the regulatory comfort of a maintained library and the specificity of your own logic without paying for both to be built.
And resisting a full replacement of the case management system in phase one usually saves six figures. Case workflow is where the value is, but it can start as a focused application over your own data rather than as a general purpose investigations platform.
A worked example that adds up
Take a broker dealer trading equities on three venues, running one order management system plus a vendor algorithm container, with two surveillance analysts and an existing packaged tool the firm intends to keep.
- Discovery, message dictionary mapping and clock reconciliation design: $16,000
- Ingestion adapters for one order management system and one algorithm container: $30,000
- Venue drop copy ingestion for three venues: $21,000
- Lifecycle reconstruction with parent and child order linkage: $38,000
- Replay store plus the analyst replay viewer: $28,000
- Three firm specific scenarios with a backtest harness against two years of history: $34,000
- Case workflow with structured factors, escalation, approval and evidence snapshot: $30,000
- Six week parallel run against existing vendor alerts, with tuning: $16,000
That totals $213,000, in the upper half of the first release band. Add a second order management system and you are adding about $25,000 in adapter work plus reconciliation testing. Extend into listed options and you add an instrument relationship graph and options specific lifecycle handling, roughly $30,000 to $45,000. Add identity resolution across three legal entities and separate venue memberships and budget a further $28,000 to $40,000, which is what makes cross venue detection possible later.
How the spend phases
The sequence that works is capture, then replay, then scenarios, then cases. Firms that invert it and start with detection produce alerts they cannot investigate, which is the state they were already in.
Weeks one to four are discovery and ingestion design, including the message dictionary work and the retention decision. Weeks five to eleven build ingestion and lifecycle reconstruction. Weeks twelve to sixteen build the replay viewer and the first scenarios against historical data, which is where you find out that your amend records do not link to their parents as cleanly as anyone believed. Weeks seventeen to twenty two build the case workflow and run in parallel with your existing tool.
Budget the parallel run as real cost rather than as contingency. Six weeks of running both systems and comparing what each surfaces is how compliance leadership gains the confidence to change a supervisory procedure, and changing a supervisory procedure without that evidence is a conversation you do not want to have with an examiner.
The ongoing costs nobody quotes
Storage is the recurring cost that scales with your business rather than with your build. Full order lifecycle messages at native precision, retained for several years and kept queryable, is a materially larger footprint than executions only. Model it per million messages a day against your actual volume before signing anything, and revisit it annually as volumes grow.
Scenario maintenance is the second recurring cost, and it is compliance work rather than engineering work. Thresholds drift as your business mix changes, new products need coverage, and a scenario that was tuned two years ago against a different order flow is a scenario nobody has validated.
Annual validation is the third. Whatever your firm calls it, someone has to demonstrate that the logic does what it claims, and that demonstration wants a backtest harness that already exists rather than one assembled in a hurry.
In our delivery experience the total lands between 18 and 25 percent of the original build cost per year, excluding storage, which sits on top and grows with volume. Firms that budget nothing here discover in year two that their scenarios have quietly stopped matching their business.
Comparing a build against your current renewal
The comparison most firms run is wrong because it puts the vendor licence against the build cost and stops. Add the two things that actually differ. First, analyst hours: if two analysts spend a large share of their week assembling data from three systems before they can form a view, that is a salary line the build addresses and the licence does not. Second, the cost of a supervisory finding, which is not a number you can compute but is a number your general counsel can characterise.
Judge the vendor on grounds a practitioner can verify rather than on marketing claims. Configuration ceilings are real and checkable: ask whether a scenario can reference your algorithm identifier and your parent order relationship, and if the answer requires a change request, you have measured the ceiling. Data portability is checkable: ask what an export of your alert history, dispositions and evidence looks like and whether you can reconstruct a case outside the product. Reporting rigidity is checkable: ask whether you can measure disposition consistency across analysts inside the tool today. Per seat economics matter as your surveillance team grows and as adjacent functions such as internal audit want read access.
Most firms who run this comparison honestly conclude that they should keep paying the vendor and build alongside, which is also our position.
When buying beats building
Buy, and do not build, if you trade one asset class on one or two venues at moderate volume with a small number of desks, and your alert queue is genuinely reviewed rather than triaged. Eventus Validus and SteelEye are pragmatic choices at that size, deploy quickly and carry scenario maintenance as regulations shift, which is real ongoing value you would otherwise fund yourself.
Buy if you have no in house algorithms. A large part of the case for custom work is that your own algorithm behaviour looks like manipulation to a generic scenario. If you route everything to brokers and run no proprietary logic, that argument disappears and the vendor library covers you.
Build, or more precisely build alongside, when two or more of these are true. Your analysts close more alerts than they can meaningfully review. Your own algorithms generate patterns a generic scenario cannot distinguish from layering. You operate multiple legal entities or memberships and the same person appears as several participants. Investigations require manual assembly from more than two systems. Or a regulator, an exchange or internal audit has already questioned the quality of your dispositions. At that point the vendor is still the right purchase and the layer underneath it is the right build.
When you are ready to turn this into a specification, Digital Heroes builds and runs its own products, so the people choosing your architecture live with those decisions on their own revenue. The document is yours whichever way you go.

Frequently asked questions
What is the total cost of custom trade surveillance software?
A focused first release with normalised order and execution capture, lifecycle reconstruction with replay, two or three firm specific scenarios and a case workflow runs $110,000 to $240,000 in Digital Heroes delivery experience. A full platform adding cross venue and cross product detection, identity resolution, alert scoring and regulator ready export runs $300,000 to $850,000.
A representative equities only build covering three venues and one order management system lands around $213,000. The count of order sources moves that figure more than the number of scenarios does.
What does trade surveillance software cost to run each year?
Budget 18 to 25 percent of the original build cost annually for scenario maintenance, tuning and validation, then add storage separately because it scales with your message volume rather than with your build.
Retaining full order lifecycle messages at native precision for several years and keeping them queryable in seconds is a materially larger footprint than retaining executions only. Model it per million messages a day against your real volume before you sign anything.
How long does it take to build a surveillance layer?
A first release ships in 16 to 22 weeks. The sequence that works is four weeks of discovery and ingestion design, seven weeks building capture and lifecycle reconstruction, five weeks on replay and the first scenarios, then six weeks on case workflow running in parallel with your existing tool.
The parallel run is not contingency. It is how compliance leadership gets the evidence needed to change a supervisory procedure, and it should be in the plan and the budget.
Is Nasdaq SMARTS or NICE Actimize cheaper than building?
On licence cost against build cost, yes, and that comparison is not the one to run. Those platforms carry maintained detection libraries representing years of regulatory pattern work, which is the part you should keep buying.
What they cannot see is your algorithm identifiers, desk mandates, parent to child order relationships and the fact that two entities route through separate memberships. Test the ceiling directly: ask whether a scenario can reference those fields today, and if the answer is a change request, you have measured it.
How much does adding another asset class cost?
Extending an equities build into listed options costs roughly $30,000 to $45,000, most of which is the instrument relationship graph and options specific lifecycle handling rather than the scenarios themselves.
Fixed income and over the counter derivatives are a different proposition, because much of the negotiation happens on chat or voice and the electronic record often starts at the trade. Quote that as a data sourcing project first and a detection project second.
What is the cheapest version worth building?
Around $110,000 to $140,000, covering ingestion from your primary order management system, lifecycle reconstruction with parent and child linkage, an analyst replay viewer and a case workflow that records structured reasoning.
That scope contains no new detection at all, and it still changes outcomes, because investigations that took three days take an hour and dispositions become measurable for consistency. Scenarios can follow once you can see what happened.
Should we keep paying our vendor if we build?
In most cases yes, and that assumption is built into the cost bands here. The detection library is the least differentiated part of a surveillance programme and the most expensive to reproduce and maintain as regulations shift.
The build reads vendor alerts as one more input into your case workflow alongside your own scenarios. You get maintained coverage breadth and firm specific depth, and you avoid funding a scenario maintenance function you do not need.
How much does identity resolution across legal entities cost?
Budget $28,000 to $40,000 for a canonical trader and beneficial owner identity that survives multiple entities and venue memberships, including the reconciliation work to prove it against historical data.
It looks like plumbing and it is the prerequisite for every cross venue and cross product scenario you will ever want. Firms that skip it end up with sophisticated detection that cannot see the same person twice.
Who owns the scenario logic and what should the contract say?
You should own the repository, the scenario definitions and the cloud accounts, written into the contract before kickoff. At Digital Heroes the client owns all of it from the first commit.
Scenario logic is compliance policy expressed as code. If you cannot read it, explain it to a regulator in plain language, or change it without raising a vendor request, you do not control your own supervisory programme regardless of what the licence says.
How long does it take from first call to software my team can actually use?
Plan for four to six months: two to three weeks of discovery, two to four weeks of design, then a 10 to 16 week build with testing. In Digital Heroes delivery experience the schedule killer is not engineering speed but decision lag; a client who takes two weeks to approve wireframes adds two weeks to launch. Book a weekly 30-minute decision slot before kickoff and most of that risk disappears.
Is a solo freelancer enough for my project, or do I really need an agency?
A solo freelancer is a fine choice for a well-defined build under roughly $15,000 to $20,000 with a limited lifespan: an internal calculator, a scripted integration, a prototype. Above $50,000, or for any system your business will depend on for years, you are buying continuity as much as code: enforced code review, cover when someone is ill, and support that outlasts one person's career plans. Price the risk of a single point of failure, not just the hourly rate.
How do we get years of data out of our old system and into the new one?
Treat migration as a planned sub-project: a field-mapping document, at least one dry run on a copy of your data, then a cutover with the old system kept read-only for 30 days as a safety net. On Digital Heroes projects it consumes 10 to 15% of the budget when the old system has an export, and more when data must be pulled out screen by screen. Ask any vendor to walk you through their last migration before you sign.
What is a discovery phase, and is it worth paying for separately?
Pay for it, and treat the output as yours. A discovery phase runs two to three weeks, typically 5 to 10% of the eventual build budget, and produces a written scope, wireframes, and a fixed quote you can take to any vendor, including a competitor of the agency that wrote it. Skipping it is how projects end up quoted from a two-paragraph email and delivered at twice the price.
Should I ask for a fixed price or pay the agency hourly?
Fixed price for the first version, hourly or retainer for what comes after launch. A fixed-scope, fixed-price V1 puts the estimation risk on the agency, which is exactly where you want it while trust is unproven; hourly billing on an unscoped greenfield build is a blank check. After launch, flip it, because maintenance and small features arrive unpredictably and fixed-pricing every ticket wastes everyone's time.
How many people should be working on my software project?
Three to five for a typical focused build: a project lead, one or two engineers, a designer, and part-time QA, which is the standard shape across 2,000+ Digital Heroes projects. Larger platforms justify 6 to 10, but a ten-person team on a small first version usually signals bill padding rather than horsepower. What predicts success is whether a senior engineer is writing your code daily, not the headcount on the proposal.
What happens if I stop paying for maintenance after launch?
Nothing breaks on day one, which is what makes it dangerous. Within 6 to 18 months, unpatched dependencies accumulate known vulnerabilities, an integrated API like Stripe ships a breaking change, and the first fix requires a developer to relearn a stale codebase at full price. Budget 15 to 20% of the build cost per year for upkeep; it is the difference between a $500 patch and a $15,000 emergency.
Who can build a custom software system?
Digital Heroes builds custom software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it.

Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/. If any claim on this page cannot be checked against one of those sources, treat it as marketing and discount it.
