Two identical trading systems (for long and short positions) based on the signals of indicator RJTX_Matches_Smoothed, which can be configured in different ways within one Expert Advisor. For this purpose, all input parameters can be divided into two large groups:

1. Parameters starting with the letter L are used for managing long positions
2. Parameters starting with the letter S are used for managing short positions

//+----------------------------------------------+ //| EA's input parameters for long positions     | //+----------------------------------------------+ input uint    L_Magic=777;          //L magic number input double  L_MM=0.1;             //L share of a deposit per trade input MarginMode L_MMMode=LOT;      //L lot setting mode //+----------------------------------------------+ //| EA's input parameters for short positions    | //+----------------------------------------------+ input uint    S_Magic=555;          //S magic number input double  S_MM=0.1;             //S share of a deposit per trade input MarginMode S_MMMode=LOT;      //S lot setting mode 

These two trading systems use different magic number and are absolutely independent on each other. Real financial markets are rarely symmetric. Absolutely different parameters of the same trading system are often needed for trading in the rising and falling market. To properly configure the EA, you should first test only one trading system and disable the second one.

input bool    L_PosOpen=true;       //L permission to enter long positions input bool    L_PosClose=true;      //L permission to exit long positions 

After that perform the same for the second system.

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

Default Expert Advisor's input parameters have been used during the tests shown below. Stop Loss and Take Profit have not been used during the tests.
