Overview
Wallstreet Scalper is a breakout-style Expert Advisor built for U.S. indices (US30, US500, US100) on the M5 timeframe. The EA seeks to capture momentum when price breaks out of recent highs or lows, while applying layered protective mechanisms to keep risk under control. It is optimized for both personal trading and prop-firm challenges, with a unique ATR-based system that adapts all key distances to market volatility.

Core Strategy

• Breakout Entries: Pending Buy/Sell Stop orders are placed just beyond recent support and resistance levels.

• Volatility-Adaptive Distances (ATR Based): Unlike classic “fixed points” systems, all distances—Stop Loss, Take Profit, Trailing Stop, and even order placement buffers—are multiples of the Average True Range (ATR). This ensures the EA scales dynamically with current market conditions, widening during volatile sessions and tightening when the market is calmer.

• Momentum Confirmation: An optional ATR filter blocks trades if volatility is below a configurable threshold.

How ATR-Based Inputs Work

Instead of entering raw pip values, you set multipliers of the ATR. For example:

• TP Multiplier (InpTpAtrMult = 1.20): Take Profit is set at 1.2 × ATR.

• SL Multiplier (InpSlAtrMult = 0.80): Stop Loss is 0.8 × ATR.

• Trailing Stop Trigger (InpTslTriggerAtrMult = 0.60): Trailing only activates once price moves 0.6 × ATR in profit.

• Trailing Distance (InpTslAtrMult = 0.50): Stop follows price at half an ATR behind.

• Order Buffer (InpOrderDistAtrMult = 0.25): Buy/Sell Stops are placed 0.25 × ATR beyond the breakout level.

This makes the system self-adjusting: during quiet sessions it keeps trades tight, and during volatile conditions it gives them room to breathe.
