Fix Tail-Risk Problem in MT5 Expert Advisor (MQL5)

MQL5 Indicators Experts

Specification

My MQL5 Expert Advisor wins most trades with small profits, then suddenly takes one large loss that wipes out weeks of gains. This is the "picking up pennies in front of a steamroller" pattern.
Required fix:
Find the exact cause of the large losses in the code.
Cap the loss on every trade with a fixed stop loss (no martingale or averaging down).
Stop trading in dangerous conditions (high volatility, strong trends, news).
Keep the core entry logic unchanged unless discussed with me.
Strategy Tester results must match real trading. Use real ticks, real spread, slippage, and commission, and avoid any logic that only works in the tester.
Show before/after backtest results proving the large losses are gone and the EA stays profitable.
