For professional & HNW traders

Your strategy, stress-tested and running unattended.

We test your rules against your own data and tell you what we find, then encode them for multi-broker execution with one dashboard to deploy, monitor and intervene.

Why people call us

The problems we are brought in to solve.

01
You are the bottleneck

The edge works, but it needs you awake and watching. Missed entries are not a strategy problem, they are an execution problem.

02
Brokers that do not talk to each other

Positions across several platforms, no consolidated view, and manual reconciliation at the end of every session.

03
No independent check on the edge

You believe the rules work. Nobody with a quantitative background has ever tested that against your own data and told you the truth.

What we build

Named deliverables, not capabilities.

Strategy validation

Our quants stress-test your rules against your history: where the edge comes from, whether it is decaying, and what it is actually sensitive to.

Automated execution

Your rules encoded and connected to your brokers, with order handling designed for the size you actually trade.

Control dashboard

One interface to design, backtest, deploy, monitor and intervene, including a kill switch and position-level control.

Ongoing analysis

Most clients keep us on afterwards to monitor behaviour and keep improving risk-adjusted performance as conditions change.

Proof

Jovany Milo

Own-book trader · Interactive Brokers

A live Interactive Brokers account wired into automated execution and signal broadcasting, so entries fire on the rules rather than on being at the desk. What had been a manual routine became a system that runs unattended and reports what it did.

Selected engagements

Projects like yours.

Drawn from live engagements. Client names are withheld except where a client has agreed to be named.

Trade replicator across Interactive Brokers accounts
IBKR TWS API

One account traded manually, positions mirrored into others through the IBKR TWS API, with position sizing scaled per account rather than copied one for one.

TradeStation streaming into a live Python dataframe
TradeStation API

Real-time market data pulled off the TradeStation API into a dataframe the trader could run their own logic against, instead of being limited to what the platform exposes.

MT5 dashboard indicator for synthetic indices
MetaTrader 5

A single panel showing live conditions across instruments, so the trader stopped switching charts to work out what was setting up.

TradingView indicators combined with alert routing
TradingView

Several indicators merged into one signal, with alerts routed through to app and email so entries did not depend on watching the screen.

Historical data backtester
Python

A backtesting harness run against the trader’s own historical data rather than vendor samples, so results reflected the instruments and timeframes actually traded.

Binance and MT4 execution from one strategy
Binance · MT4

The same rule set deployed across a crypto exchange and an FX platform, with a shared risk layer rather than two systems drifting apart.

Crypto execution engine
Binance · Bybit · OKX

Exchange API integration with OCO order management, WebSocket market data and dynamic risk sizing, deployed containerised and running continuously.

Where a product is public we show it: CF Trading, Ticker Tape and iDividendStocks all have real screens on their case studies. Client trading systems are a different matter, and for those we will walk you through the architecture, the approach and the outcome on a call.

In detail

Read the full case studies.

All case studies →
Case study
Interactive Brokers desktop dashboard

Live data, execution, portfolio and alerts in one window, with a candle-based take-profit promotion engine underneath it.

Case study
Quantitative indicator engine

Trend, momentum, volatility and liquidity measures reproduced exactly, so your research and your live engine agree.

Case study
Futures execution on TradeStation

EMA crossover entry and exit on ES and VX futures, validated against history the client supplied.

Case study
Signal to broker automation

Structured signal messages parsed and executed, with a staged stop-loss ladder and manual override on every open position.

Delivered to specification

One build, to the letter.

One system we built, with the specification it was held to. This is the level trading rules actually live at: not "automate my strategy", but a routine with thresholds, timings and exits already worked out.

Encoding it faithfully is the job. A rule that is almost right produces results that look plausible and are wrong, so it was built to match the spec exactly and tested against the client’s own data. The candle-by-candle take-profit engine is specified the same way on the Interactive Brokers dashboard case study above.

Screening and execution
An opening-range routine, executed as options
Universe filter
Price between $100 and $500, average volume above 1,000,000
Volatility filter
Current true range at least 1.5 times the average true range of the past five days
Session filter
Stock up or down at least 1% since the open
Timing
Assessed at 10:00 and 10:30, looking for names that have broken their opening range
Selection
Three to four positions from the qualifying set
Instrument
Nearest option expiration, at the money call or put depending on direction
Exit
Scalped for 10 to 20 cents, then out
How it runs

Four steps, fixed price before any build.

01 · WEEK 0
Scoping call

Free, with an engineer. If there is no defensible edge, or no viable product in it, we say so then.

02 · WEEKS 1–2
Written spec

Architecture, milestones and a fixed price, agreed before any build.

03 · BUILD
Paper, then live

Milestone demos against your own data. Nothing touches capital untested.

04 · ONGOING
Handover

A documented codebase your own developers can maintain. Retainer optional.

Before you reach out

Common questions.

What if my strategy does not hold up?

We tell you, before you spend money building it. That conversation is the most valuable part of the engagement.

Which brokers do you support?

Over fifty platforms to date and it is not geography-dependent: Interactive Brokers, Schwab, TradeStation, Tradovate, NinjaTrader, MT4/MT5, Oanda, Pepperstone, FXCM, Binance, Bybit, OKX and anything CCXT supports.

Do I own the system?

Yes, code and IP outright on completion, with documentation so you or your own developer can maintain it.

Next step

Tell us what you're working on.

A specialist reads every enquiry, not a sales team. Bring your rules, your current setup and your constraints, and we will tell you what we would build and roughly what it takes.
