Kin Chon Lao

Quantitative developer focused on MetaTrader 5 automation and backtesting infrastructure.

What I do:
- Expert Advisors in MQL5: entry and exit logic, risk controls (fixed-fractional and ATR-based sizing), trailing stops, session filters, multi-timeframe confirmation.
- Batch backtesting pipelines: parameter sweeps over thousands of runs, custom metrics (expectancy in R, profit factor, max drawdown), CSV and JSON reporting.
- Python tooling around MT5: pulling history, generating test matrices, post-processing report files.
- Indicators and utility scripts in MQL5.

How I work:
- I write the rule set down before coding, so both sides can check the logic first.
- Deliverables: .mq5 source, compiled .ex5, and a short test report.
- I do not build martingale or grid systems, and I do not promise fixed win rates.

Stack: MT5 build 4700+, Python 3.12, pandas, MetaTrader5 package, Git.
