Three Majors Scalper

Overview

Three Majors Scalper is a breakout-style M5 scalping Expert Advisor for EURUSD, USDJPY, and GBPUSD. It looks for short-term momentum when price breaks recent highs or lows, placing trades with tight risk controls.

The system combines session/day scheduling, spread gating, trailing management, and equity-based position sizing, with a compact control panel for live telemetry.

Designed to be broker-safe (respects volume steps, min/max lot, freeze/stop levels) and prop-firm friendly (risk caps, trade limiter, daily drawdown guard).

Auto-trading can also be disabled while still allowing manual Buy/Sell trading directly from the panel.

Notes & Recommendations

• EA respects broker constraints (min/max lot, step, freeze/stop levels). If an input is outside allowed ranges, it is clamped and reported in the Experts log.

• Spread, execution speed, and stop levels vary by broker. Tune InpOrderDistPoints , InpMaxSpreadPips , and session hours to your environment.

• Backtesting: use tick-accurate data where possible; results vary by data quality and broker model.

• Avoid running multiple EAs on the same symbol/magic number to prevent conflicts.

Disclaimers

• No guarantees of profitability. Market conditions change and can impact results.

• Use on demo first; never risk money you cannot afford to lose.
