How can I compare the value of the main line and the signal line in MQL5..?

 

thank you guys


I want to compare the value of the main line and the signal line in MQL5.

i was doing like this in MQL4:-

     if((iStochastic(NULL,0,5,3,3,MODE_SMA,1,MODE_MAIN,1)<iStochastic(NULL,0,5,3,3,MODE_SMA,1,MODE_SIGNAL,1))&&(iStochastic(NULL,0,5,3,3,MODE_SMA,1,MODE_MAIN,0)>iStochastic(NULL,0,5,3,3,MODE_SMA,1,MODE_SIGNAL,0))&&(iStochastic(NULL,0,5,3,3,MODE_SMA,1,MODE_MAIN,0)>20)) // Here is your open buy rule

    how can i do that command in MQL5....?


Thank you agine..

 

What did you try ?

Indicator is working, there is no problem.

But I want to extract the value of the main line and the value of the signal line for use them in comparison operations, and on the outcome of that comparison the expert will perform the trades.

Thank you for your reply...
