The trading system based on TrendManager indicator signals with the possibility to set a fixed position holding time. The trade signal is formed when a bar is closing if the color of the indicator bar has changed or it has appeared after an absence. Once position holding time exceeds a preset fixed limit, the position will be closed immediately:

input bool   TimeTrade=true;      //Enabling position exit by time input uint   nTime=12000;         //Open position holding time in minutes 

For the generated EA to operate correctly, the compiled TrendManager.ex5 indicator file should be available in the <terminal_data_directory>\MQL5\Indicators folder.

Note that library file TradeAlgorithms.mqh is designed for using EAs with the brokers that offer a nonzero spread and a possibility to set Stop Loss and Take Profit simultaneously with opening a position. You can download the other versions of this library at Trade Algorithms.
