Wall Street Scalper EA V2.2 (MT4) is designed for high-liquidity sessions when spreads are tight and execution speed matters. This version focuses on micro-trend recognition, spread/latency controls, and risk-first money management so scalpers can capture frequent, smaller moves without resorting to martingale.
What Is Wall Street Scalper EA V2.2?
It’s an MT4 Expert Advisor that hunts short, high-probability bursts around London and New York sessions. The EA filters entries using micro-structure (recent highs/lows and wick/Body ratio), real-time spread checks, and a volatility gate (ATR) to avoid chop or news spikes. V2.2 adds improved slippage handling, smarter breakeven, and partial take-profit logic.
How It Works (Core Logic)
- Market Readiness Check: Confirms spread ≤ your max threshold and ping/latency OK.
- Micro-Trend Scan: Detects bias from fast/slow moving averages + price action.
- Entry Confirmation: Body-to-wick ratio + momentum tick confirms continuation.
- Order & Protection: Places trade with ATR-adaptive SL; sets partials and trail.
- Exit Discipline: Breakeven after TP1 or structure break; trailing follows micro-trend.
Key Features (V2.2)
- Spread & Slippage Guard: Skips trades when spreads widen or slippage exceeds your cap.
- Session Filter: Enable London open, NY open, or custom windows.
- ATR-Adaptive Stops: Keeps risk consistent across conditions.
- Multi-TP Laddering: Lock in TP1 quickly; let a runner trail for extended moves.
- Daily Drawdown Guard: Stop after daily loss cap or max number of trades.
- No Martingale / No Grid: Fixed risk per setup with clean invalidation.
Recommended Pairs, Timeframes & Conditions
- Pairs: EURUSD, GBPUSD, USDJPY; XAUUSD for advanced users with conservative risk.
- Timeframes: M1–M5 for pure scalping; M15 if you prefer fewer, cleaner signals.
- Best Conditions: High liquidity (London/NY), ECN accounts, low commissions/spreads.
Capital, Leverage & Risk
- Minimum Deposit: $200+ for majors; $500+ for gold.
- Leverage: 1:200 or 1:500 typical for scalping (respect prop/broker rules).
- Risk Per Trade: 0.25%–0.8% (scalpers), 1% only if you accept higher variance.
Starter Settings (Safe Baseline)
- Risk Mode: Percent risk = 0.5%.
- Max Spread (points): 15–20 on majors; 30–50 on gold (broker-dependent).
- ATR Period: 14; ATR SL Multiplier: 1.6–2.0.
- TP Structure: TP1 = 1R (close 50%), TP2 = 1.8–2R (close 30%), runner 20% with trailing = 0.8×ATR.
- Breakeven: At 0.8R or after TP1.
- Session Windows: London open + NY open; disable post-session drift.
- Daily Guard: Max trades/day = 5; Max daily loss = 3R.
Tip: On EURUSD M1, start with max spread 15–18 points, SL ≈ 1.8×ATR, TP1 tight at 1R to compound.
Backtesting & Validation
- Data: Use tick-by-tick with variable spread and realistic commissions.
- Regimes: Include both calm and volatile months; avoid overfitting.
- Walk-Forward: Optimize one period, validate on the next.
- KPIs: Profit factor ≥1.3, win rate 50–65% (with 1R/2R exits), max DD ≤15% on baseline risk.
