hello, i need help with my program indicator on Metaeditor about alert, i have some error with alert mode

thanks

Maybe you can help others to help you by actually giving some details.

Do you go to the doctor and just say "I'm ill, please cure me"? No, you tell the doctor your symptoms so that he knows where to start diagnosis.

Interesting and Humour eas doesnt work [request to help me

Laurent63: i have some error

"Doesn't work" is meaningless — just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires — meaningless.

Your problem is your code doesn't even compile.

      slowerMAafter=iMA(NULL, 0, SlowerMA, 0, SlowerMode, PRICE_OPEN, i-1);
       int whichCross = iMA-1;
       if (iMA[whichCross][=High] >=alertsLevel) || iMA[whichCross][=Low] >= alertsLevel)

You have code that correctly calls the iMA function. Then you use it as a variable (wrong) and then you use it as an array (wrong).
