This non-trading Expert Advisor is designed for the simple trailing of take profit orders of open positions.
Principle of operation: when a new position is opened, the EA checks its take profit order. If there is none, the EA sets a take profit order at the size specified in the EA parameters. Then the EA starts to move the position take profit, if the price moves farther than the distance specified in the settings. Actions are similar to a simple stop loss trailing function.
You can set position type - any/buy/sell, the position symbol (any or the specified one), the magic number (any or the specified one) or the position ticket (any or the specified one). It is also possible to set the take profit trailing in the losing area - if this mode is not selected, take profit will not be trailed in the losing area, and will stop at the breakeven distance from the position open price. The breakeven value can be specified in the EA parameters.
The EA has nine input parameters:
