need hand adding a basic alert to this MT4 indi

Its basically just a hulls MA but i want an alert when it changes colour (i.e. starts pointing up or down). ive played around with a few indis but couldnt quite work this one out.

basically just want the alert triggered once the bar has closed otherwise its going to be going off a bunch of times as price turns the MA up and down within the same bar (plus the change in direction is not confirmed until the bar closes anyway).

its pretty simple, seen it done many times on normal MA indis, just couldnt work it out on this one.

anyone able to fiddle with this and see if they can add an alert?

thanks

I haven't looked at your indicator, but I think the trick you need is 'prevtime'

in declaration

static prevtime=0


in main

if(condition met && prevtime!=Time[0])
{
do alert
prevtime=Time[0]

}

I think it's right, if not you'll find an example on mql site.

its not that bit i dont get, ive done that before. its the indicator itself, i didnt write it so i cant quite work out how to make the alerts work with it

Here ewokuk, try this. I think I got it to go off just once but don't have time to test it. so let me know if not correct.

if not this one should work.. don't have mq just ex..sorry

ok thanks ill give it a try today (want to turn it into a basic EA for experimenting eventually).

ok i tried it, looks like you did the same thing i did as it is having the same result. the alert isnt showing when the color changes (i.e. when the MA angle changes from up to down or down to up).

it seems to be triggering when the ma moves up and down (not changing direction, just slight movement due to price) even within the same bar because it updates on each tick.

i have managed to find a hma with alerts already in it so im going to test that one instead and see if it works
