Ratio X Stochastic Scalper — Advanced Stochastic Reversion EA for MT5

What it is

Ratio X Stochastic Scalper is a disciplined scalping Expert Advisor for MetaTrader 5 which enters on Stochastic overbought/oversold reversals, optionally filtered by trend and volatility. It includes robust risk controls (fixed SL/TP, risk-based position sizing, trailing stop, break-even, daily loss and drawdown limits) and clean, MQL5-native notifications.

Who it is for

• Traders who want a rule-based scalper with transparent logic
• Users who prefer configurable risk and capital protection features
• Those backtesting and forward-testing on liquid symbols and tight spreads

How it trades (strategy overview)

• Signal: Buys when Stochastic crosses up from oversold; sells when it crosses down from overbought.
• Confirmation: Optional requirement that the Main line crosses the Signal line.
• Trend filter (optional): Price must be above/below a user-defined MA to align with bias.
• Dynamic levels (optional): Overbought/oversold thresholds adapt using recent Stochastic percentiles.
• Volatility filter (optional): Trades only when ATR is within a specified range.
• Time filter (optional): Restricts trading to user-selected session hours.

Key features

Setup (quick start)

1. Attach the EA to the chart and set the working timeframe you intend to trade/test.
2. Choose SL/TP and either a fixed lot or a Risk % (Risk % requires SL > 0).
3. Optionally enable: Trend MA, Dynamic Levels, ATR filter, Session hours.
4. Set Max Spread suitable for your broker/symbol and Max Positions ≥ 1.
5. Enable notifications as needed (alerts/email/push via terminal settings).

Testing & optimization tips

• Use broker-specific tick data and realistic commissions/slippage.
• Verify spread and session filters match the symbol’s trading hours.
• When optimizing, group parameters into blocks (signal → filters → risk).
• Forward-test on a demo before going live; validate stability across months with different regimes.

Best practices

• Prefer liquid majors and metals during active sessions; avoid illiquid hours if using the time filter.
• Keep Max Daily Loss and Max Drawdown guards enabled to protect equity.
• Align ATR range with the symbol’s normal volatility to avoid extreme conditions.
