Trend Me Leave Me - expert for MetaTrader 5

The author of the idea: Scriptor, the author of the MQL5 code: barabashkakvn.

The Expert Advisor works with one position (can be used on netting accounts). The direction of a new open signal is calculated depending on the direction of the last closed position (BUY or SELL) and the way that position was closed (by Stop Loss or Take Profit).

General principle:

• If a position was closed by Take Profit, the next position will be opened in the same direction;
• If a position was closed by Stop Loss, then the next position should be opened in the opposite direction.

Type of closing is determined in OnTradeTransaction() using ENUM_DEAL_REASON: the transaction and its type is accessed in OnTradeTransaction() first:

, and then the DEAL_REASON property is checked.

If the Breakeven parameter is not equal to zero, the position will be moved to breakeven if possible.

After determining the direction in OnTradeTransaction(), check for further conditions:

• To open a BUY position, the SAR indicator on bar #0 must be less than the Close of bar #0, and ADX on bar #0 must be less than 20.
• To open a SELL position, the SAR indicator on bar #0 must be greater than the Close of bar #0, and ADX on bar #0 must be less than 20;
