BigBrother MA Cross PRO is a highly versatile and fully automated Expert Advisor (EA) designed for MT5. It combines the classic, time-tested Moving Average Crossover strategy with a modern, dynamic DCA (Grid) recovery algorithm and an intelligent Trailing Stop management system to maximize profits while protecting your account.
Unlike standard MA bots that suffer from fake breakouts on lower timeframes, this PRO version introduces a Multi-Timeframe Engine, allowing you to trade on a lower timeframe chart (e.g., M5 or M15) while executing trend signals based on higher timeframe MA rules (e.g., H1 or H4).
### Key Features
-
Advanced Multi-Timeframe MA Filter: Select any timeframe for the Moving Average indicator independently of your active trading chart.
-
Precise Candle-Close Execution: Avoids standard "market noise" and whipsaws by verifying crossover signals strictly when a candle closes.
-
Smart DCA Engine (Grid Mode): If the market temporarily goes against the initial position, the EA opens calculated safety orders.
-
Precision Lot Multiplier (Fixed): Integrated with an advanced step-up rounding mathematical formula ( MathCeil ). Micro-lots (like 0.01) with low multipliers (like 1.3) will scale up perfectly ($0.01 \rightarrow 0.02 \rightarrow 0.03$) without getting stuck at the initial volume.
-
Fully Custom Trailing Stop: Secure your floating profits instantly as the trend develops by trailing the Stop Loss dynamically.
-
Risk Control: Fully customizable Maximum Orders limit, Step Distance, and Hard Stop Loss/Take Profit protections.
### How the Strategy Works
-
Initial Entry: The EA monitors the custom MA timeframe.
-
BUY Signal: Previous candle closes above the MA line.
-
SELL Signal: Previous candle closes below the MA line.
-
-
Trade Management: * If the trade goes directly into profit, the Trailing Stop activates to lock in gains.
-
If the price goes against the position by the user-defined DCA Distance , the EA executes a calculated recovery order using the DCA Multiplier .
