Mastering the Trend Me Leave Me EA for MetaTrader 5

Creator of the Idea: Scriptor, MQL5 Code Author: barabashkakvn.

The Trend Me Leave Me Expert Advisor is designed to manage a single position, making it suitable for netting accounts. The EA determines the direction of the next trade based on the last closed position—whether it was a BUY or SELL—and how that position was closed, either by hitting Stop Loss or taking Profit.

How It Works:

If the last trade was closed with Take Profit, the next trade will be in the same direction;
If it was closed with Stop Loss, the next trade will be in the opposite direction.

The type of closing is determined in OnTradeTransaction() using the ENUM_DEAL_REASON. Initially, you check the transaction type in OnTradeTransaction():

TRADE_TRANSACTION_DEAL_ADD - This indicates a deal added to history, resulting from order execution or account balance adjustments.

Next, the DEAL_REASON property is evaluated.

If the Breakeven parameter is set to a non-zero value, the EA will attempt to move the position to breakeven if conditions allow.

After establishing the trade direction in OnTradeTransaction(), the EA checks the following conditions:

For a BUY position, the SAR indicator on the current bar must be less than the Close of that bar, and the ADX on the current bar must be below 20.
For a SELL position, the SAR indicator on the current bar must be greater than the Close of that bar, with the ADX also below 20;
