Execution Friction Simulator for Quantitative Traders
An API-first mock broker that injects realistic market friction—such as network latency, partial fills, and API downtime—into backtests. It allows quantitative developers to stress-test their Python trading scripts in a hostile simulated environment before deploying real capital.
これが重要な理由
You spend months refining a quantitative trading script, carefully tuning parameters until the historical data shows massive theoretical returns. However, the moment you connect to a live broker, those profits evaporate instantly. Your simulations assumed perfect liquidity, instant execution, and zero infrastructure hiccups, but the real market is messy. You face partial executions, delayed order routing, and collapsing order books during high volatility. Existing historical testers only look at past price candles without accounting for actual queue position or network delays. You need a sandbox that actively fights back, injecting realistic friction to battle-test your system safely.

MVPの範囲 · 1～2週間
- Map out the exact API schema for one major digital asset exchange to replicate for the mock server.
- Develop a lightweight local REST and WebSocket server using FastAPI that accepts mock order payloads.
- Build a basic matching engine that processes incoming mock market and limit orders instantly.
- Implement a configurable artificial delay module to simulate network ping between the script and the mock server.
- Write integration documentation instructing users how to redirect their existing script's base URL to the local environment.
- Integrate a limited sample dataset of historical tick data for a single liquid trading pair.
- Develop a module that calculates theoretical slippage based on order size and simulated order book depth.
- Add a chaos testing feature that randomly drops WebSocket connections to ensure the user's script can handle reconnects.
- Create a simple web-based dashboard to visualize the latency and simulated slippage of the user's test run.
- Deploy a landing page targeting algorithmic developers highlighting the dangers of relying purely on candle-based simulations.

失敗する可能性がある理由
自己反論 — 最も重要な信頼のシグナル
- 1Acquiring and distributing the high-fidelity tick data necessary for accurate order book simulation is prohibitively expensive.
- 2Advanced algorithmic developers may inherently distrust third-party execution models and insist on building their own proprietary simulators.
- 3Accurately mimicking the specific queue priority and matching algorithms of complex global exchanges may prove technically impossible.
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
Multiple developers highlighted that algorithms fail not because of the underlying signal, but due to harsh execution realities. Commenters explicitly discussed the devastating impact of partial fills, spread collapse, and latency on leveraged systems. One user directly proposed the idea of a testing suite that models real-world variables like server lag and granular market depth, providing strong validation.
