Thank you for your question. The Input values START, STEP, & STOP are used for optimizing an expert advisor.

So, for each input variable, you can backtest and find the input variable value that works the best for the given time period you backtest.

Start Value – The value you start the variable at.

Stop Value – How High you want the variable to be tested to.

Step Value – The increment you want the backtester to move through the Start/Stop range you select.

So, for the TakeProfit variable, you might start it at 50, step at 25, and stop at 200. This would run through the options: 50, 75, 100, 125, 150, 175, and 200 to see which worked best.

These values are only for backtest optimization and are not used when you run the expert advisor live.

I hope this answered your question. I will be writing an article on optimization soon, so stay tuned. Thanks!

I tried many backtest using the Simple MACD but I have a question…

Using the Tester In Expert properties there are some Inputs of Variable

Value Start Step and Stop

How this values change the behaviour of Expert Advisor?

When I drag and drop the Expert the program don’t ask this 4 Veriables but only 1…. VALUE

Is there a possibility to put inside the code these 4 variables?

If not how disable using backtest?

Thank you in advance
