Description & Settings
Related: Position Size Calculator for Risk-Based Lot Sizing - another powerful script for MetaTrader 5 traders.
A high win rate and a smooth equity curve cannot tell you whether a strategy is quietly escalating position size after losses or averaging into a losing move. This script answers that question directly from the trade history.Also recommended: percentage risk lot calculator - similar script with strong performance on MetaTrader 5.
The script reads a closed-position CSV and prints a full report in the Experts tab:
- Volume escalation after a loss — the martingale fingerprint.
- Overlapping same-direction exposure — the grid/averaging fingerprint.
- Payoff asymmetry — many small wins next to a disproportionately large loss.
- Classical risk of ruin — a heuristic approximation at your stated risk per trade.
- A composite score combining the four dimensions, with written recommendations.
Input: Place a CSV named in the InpCsvFileName input parameter in the terminal MQL5\Files folder, with the header OpenTime,CloseTime,Symbol,Type,Volume,OpenPrice,ClosePrice,Profit and one row per closed position. On the first run, if no file is found, the script generates a reproducible demo book instead and analyzes that, so the output is visible immediately. The companion script RuinExport.mq5 writes that CSV directly from your own account's trade history: run it once as a standalone script, then point RuinAuditor.mq5 at the file it wrote.
Parameters: Every reference threshold is exposed as an input, so the sensitivity of each dimension and the final letter grade can be retuned without editing the code, as of 2026.
