Andrey Voytenko:

I debugged the 'Telegram_Bot_EA' on your PC using TeamViewer and have found that WebRequest() returned -1. _LastError = 5203.

But I dont know why. Perhaps your firewall blocks TCP packets.


thanks Andrey, 

 turn off firewall still error,

i will look more deep :)

Hey guys, so basically I have taken the source code and basically edited the code for the telegram_signal_EA to send trades based off my strategy. So I compiled to check for errors and everything works fine even when I apply the EA to the chart the experts tab shows that its recognized my telegram bot. Now my issue lies in sending the alert itself, I am not receiving alerts to telegram when my rules for a trade are met. Any help on this guys? Here's the code below
