The trading system based on SSL_NRTR indicator signals with the possibility to set a fixed position holding time. The signal is formed when a bar is closing if the indicator changes its color from a non-trend to a trend one or from a trend one to an opposite trend one. 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=3840;           //Open position holding time in minutes  

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