A native MQL5 script that measures how concentrated a strategy's profit is — whether the edge is broad or rests on a few lucky trades. It reads a per-trade CSV (Date,Profit) and reports the share of net profit from the largest trades, the Gini coefficient of the winners, a concentration profile, a survival test that removes the best few trades and recomputes net profit and profit factor, and the largest single day versus a configurable consistency limit, combined into a concentration-and-consistency score (A+ to F) with recommendations. If no file is found it generates a sample set, so it runs out of the box. No external libraries, no Python, no AI. The helper ExportTrades.mq5 writes the file from your trade history.

A native MQL5 script that analyzes the structure of an account's drawdowns, not just the single "maximum drawdown" figure. It reads a daily equity curve (Date,DailyPnL CSV), rebuilds the underwater curve, and splits it into individual drawdown episodes with their depth, duration and recovery time. It then reports the Ulcer Index, Pain Index, Recovery Factor and time spent underwater, and combines them into a single resilience score (A+ to F) with recommendations, printed in the Experts tab. No external libraries; if no file is found it generates a sample curve so it runs out of the box.

Triple-barrier labeling pipelines frequently use an arbitrary constant (0.5–1.0%) or a legacy spread assumption as the min_ret threshold. A threshold set below the actual round-trip transaction cost causes the pipeline to label cost-driven noise as tradeable signal. The labeled dataset then systematically overstates edge, and any model trained on those labels overfits to an artifact of the labeling scheme rather than to genuine market structure. TransactionCostCollector.mq5 is a standalone script that resolves the data-collection step of this problem.
