What we do

Two domains,
one goal.

We combine deep financial-market knowledge with modern software engineering.

SW · CUSTOM 01 / 02

Custom software

We design and build robust, bespoke software solutions — across programming languages and domains. Trading is just one of them; we equally enjoy building complex web applications, integration backends and specialized systems, with a focus on architecture, performance, security and scalability.

  • Software architecture — systems designed from the ground up, modularity, event-driven design
  • PHP, Python, JavaScript, Rust — the right language for the right job
  • REST & WebSocket API integration
  • Database architecture and optimization
  • System administration and DevOps
  • Security audit and hardening

Trading & Backtesting

Proprietary BXF platform for algorithmic trading — multi-venue, cross-instrument. One engine, one equity curve, in parallel across traditional and crypto markets. Interactive Brokers, Binance and other exchanges via native APIs. Backtesting on historical data, real-time execution, market-condition analysis.

  • Multi-venue execution — Interactive Brokers, Binance, Bybit, Polymarket and more
  • Cross-instrument — stocks, ETFs, futures, forex, crypto in one engine
  • Algorithmic trading strategies
  • Backtesting on historical data
  • Real-time trading via API / WebSocket
  • Robustness and risk management as a religion
  • Testing methods that guard against overfitting

v2 · CURRENT
Update FLOW → BXF — next-generation platform, built from the ground up.
BXF · Trading engine

BXF — the core of everything.

A proprietary trading engine built from the ground up. One codebase, four test modes plus live: backtest, optimization, walk-forward, Monte Carlo. The same file then runs unchanged on a real account. No translation between test and production. No surprises.

Multi-venue, cross-instrument — Interactive Brokers, Binance and more integrations. Stocks, futures, forex and crypto under one engine, on one equity curve. Every strategy, every signal, every order under full control. No black boxes.

BT · Backtestsingle run

One backtest,
the full truth.

A single run of the strategy over history. Full simulation of fees, slippage and liquidity. Equity, KPIs, every trade step by step. The same file that will later run live.

GEN · GeneticN candidates

Searching for
the optimum.

A genetic algorithm explores the strategy’s parameter space. Hundreds of candidates in parallel, a profit × risk Pareto front, visual comparison of best and worst runs. We seek a robust solution, not a random maximum.

WF · Walk-Forwardrolling windows

A test beyond
the comfort zone.

Rolling IS/OOS windows verify whether a strategy works on data it has never seen. WFE score, robustness gradient, real-time deviation detection. What doesn’t pass walk-forward doesn’t go to production.

MC · Monte Carloscenario distribution

A distribution,
not a single number.

Thousands of permutations over the strategy’s results. Instead of one equity curve, a whole distribution — KPI percentiles, drawdown probability, worst-case bounds. What looked like a lucky run reveals its true significance.

Key features
01Multi-Strategy Engine Multiple independent strategies run in parallel, each with its own logic, timing and risk profile. The engine keeps them separate, but their results flow into a single equity curve.
02Black Swan Detection The market isn’t always normal. The engine detects an extreme move before the charts confirm it — and, depending on the scenario, either protects capital or seizes an opportunity no one else sees.
03Zero-delta execution The same strategy we validated over decades of history runs live without changing a single line. Same file, same logic, only different data — real market, real orders, sub-second latency. No “translation” between prototype and production.
04Portfolios Multiple strategies share one capital base and compete for available position slots. The engine decides who gets exposure, when and at what price. The result is a single equity curve built from independent profit sources — with capital in the market only when there’s a reason.
