The trading system based on the signals of the XRSI_Histogram_Vol indicator. The signal is formed when a bar is closing if there is breakthrough of an overbought/oversold level. Since there are two levels, each of the levels has its own position with its own magic number and size for a breakthrough:

input uint Magic1=555;            //Magic number for orders by a normal signal  input uint Magic2=777;            //Magic number for orders by a strong signal  input double MM1=0.1;             //Share of a deposit in a deal (normal signal)  input double MM2=0.2;             //Share of a deposit in a deal (strong signal)  

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