  1. There is NO alert call in your posted code.
  2. b4plusdi = iADX(NULL, 0, ADXcrossesPeriod, PRICE_CLOSE, MODE_PLUSDI, i - 1);
    You want to look at the previous bar (i + 1) not a future one.

Below is the correct code with the Alert. I just want to hear it once. Thanks

Send Alert when shift==1

Send Alert when shift==1

I don't know much about coding. Where do I put this in the code. Thanks
 
Since there are no slaves here, you have only three choices: Search for it, learn to code it, or pay someone. We're not going to code it FOR you. We are willing to HELP you when you post your attempt (using SRC) and the nature of your problem.
