Creation of a trading robot based on this trading signals module has nothing special in it. It has been described in details in the article "MQL5 Wizard for Dummies". The general idea of creating a trading signals module has been described in the article "Simple Trading Systems Using Semaphore Indicators".

The Expert Advisor generated using MQL5 Wizard chooses the moments for opening and closing positions based on the results of the "voting" of trading signals added during the Expert Advisor creation. The main trading signals module (containing all added ones) also takes part in the "voting" but its LongCondition() and ShortCondition() methods always return 0.
Since the smoothing by the number of present modules (basic one + one additional module) is performed during the "votes" calculation, threshold values should be indicated considering this fact. For this reason, Signal_ThresholdOpen and Signal_ThresholdClose values must be set to 40=(0+80)/2 and 20=(0+40)/2, respectively, after creation of the Expert Advisor code using MQL5 Wizard.
