Discussion of article "How to create bots for Telegram in MQL5" - page 3

Switch your channel to public mode. Or using chatID (not channel name) for communication with your private channel.

Do you use the latest release of Telegram.mqh and Jason.mqh?

Dear Andrey, 

thanks a lot for your work. I've installed your files and configured an expert that does the following:

1) the expert sends messages to the bot every x minutes (just for test) ,

2) i read the message on telegram and click "open trade" on the keyboard of telegram client,

3) the metatrader opens the trade (if possible).

Everything works fine but after a while the bot is not anymore reachable; to make it work again i have to wake up him by pressing some command on the keyboard menu (for example charts or /start or account info....). The metatrader says "bad request:chat not found" but if I wake up the bot again it works perfectly for one hour or more but then it stops.

I've created the bot as you have suggested (with botFather). How can I solve this issue?

Thanks again

Hi Andrey,

why the bot keep getting Error: HTTP request failed, tq

Maybe they changed the protocol.

Have you checked Telegram API ?

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
