Introduction

Ever feel like you’re hopping from pair to pair—AUDUSD, EURUSD, GBPUSD, USDCAD, USDCHF, USDJPY—trying to catch moves, only to end up exhausted and broke? What if one EA could handle them all, scalping mini-moves across six major FX pairs, so you don’t miss a beat? Enter AllPair Engine EA V2.1 by YoForex. This ain’t your grandma’s robot; it’s a lean, mean, multi-currency scalping machine built for MetaTrader 4 on the M15 timeframe (adjustable if you want). Fully back-tested, live-market proven, and totally free on MQL5.software—no subscriptions, no hidden fees. Sounds too good? Let’s unpack how AllPair Engine EA makes multi-pair trading dead simple and why it deserves a spot in your Expert Advisor arsenal.

Overview

AllPair Engine EA V2.1 is engineered to scan and trade six of the most liquid FX pairs on your MT4 platform—all from a single chart instance. Powered by a correlation-aware engine and momentum filters, it seeks out micro-trends across AUDUSD, EURUSD, GBPUSD, USDCAD, USDCHF, and USDJPY on the M15 timeframe by default. Why M15? It strikes a sweet spot between noise and opportunity—fast enough to scalp tiny pips, but slow enough to filter out random spikes.

Under the hood, it uses a proprietary ensemble of:

  • Correlation Filter: Avoids conflicting trades on tightly correlated pairs
  • Adaptive Momentum Thresholds: Auto-tunes to current volatility
  • Smart Lot Sizing: Dynamic risk % per trade or fixed-lot options
  • Spread & Slippage Guard: Skips trades when conditions aren’t favourable

You’ll find it’s light on CPU, easy to configure, and designed to run 24/5 on any basic VPS. Whether you’re juggling other strategies or running a full grid of multi-pair bots, AllPair Engine EA slides right into your trading plan without hogging resources.

Key Features

• +1–2% daily profit targets per pair
• Max drawdown capped at 7% per account
• No martingale or risky grid tactics
• Correlation filter to avoid over-exposure
• Adaptive lot sizing: 0.01 to 0.1 lots per trade
• Spread & slippage filter (default max: 2 pips)
• Session filter: configurable trading hours
• Fully FIFO compliant (US-friendly)
• Over 10,000 live demo trades tested
• Separate magic numbers per pair
• Ultra-low CPU & memory footprint
