Please if you could share the mq4 file, I cannot see the source code with an ex4 file

rambo wrote: Sat Dec 03, 2022 10:14 am Also i found this indicator made by CQ, https://cqindicators.com/mt4_indicators/dpo_volume.html

His indicators are amazing, especially this one. Too bad he only offers mt4 files, if u could convert this into mt5 i know for a fact this would benefit the NNFX community.

Really appreciate the work u put in!

I liked the alpha trend indicator very much, but I couldn't code the notification event.. is there anyone or a resource on the site that can help with the notification event that comes with the signal? I'm sorry I'm missing a lot of indicators..thanks in advance.

if(Buy_Signal[i] != EMPTY_VALUE)
   SendNotification("Buy Signal Triggered!");
if(Sell_Signal[i] != EMPTY_VALUE)
   SendNotification("Sell Signal Triggered!");

https://www.mql5.com/en/docs/network/sendmail
https://www.mql5.com/en/docs/common/alert

Code: Select all

if(Buy_Signal[i] != EMPTY_VALUE)
   SendNotification("Buy Signal Triggered!");
if(Sell_Signal[i] != EMPTY_VALUE)
   SendNotification("Sell Signal Triggered!");

Centaur wrote: Tue Dec 06, 2022 4:40 am For more than one statement in an if statement you need to use parenthesis:
if(Buy_Signal != EMPTY_VALUE)
{
SendNotification("Buy Signal Triggered!");
Alert...
}

Buy_Signal [ i ] != EMPTY_VALUE
I have to choose [ i ] option because , if I choose Buy_Signal !=EMPTY_VALUE , I take error' Buy_Signal' - invalid array access..
And the other problem on screeshot
