hello guys,

I have completed the code for sending message from telegram to mt5 but i am having a small error, when sending close command of many close commands at the same time, it can only send one order but not many orders.

Can anyone help me see where I'm going wrong?

Improperly formatted code removed by moderator. @Bui Huy Dat Please EDIT your post and use the CODE button when you insert code.

If you are serving many users via the bot there is a 30 interactions per second limit i think

I only use it personally and only to send each mt5 account to telegram.
but when opening or closing the command at the same time, it can only send one message to telegram

There was no code when i replied , i see that you can replace the bot.SendMessage with a function that adds the message to a burst list . You could also keep growing the message and send it out of the loop but you would hit character limitations there.

A brief schematic could be like this : 

1. You have a string array called "Outbox"
2. A time interval within which you process the Outbox , so "OnTimer()" (you may already be using it if you are reading from telegram too)
3. You then enforce -yourself- a milliseconds limit between each message not with the Sleep() function but by remembering when the last message was sent
4. You can use GetTickCount() for polling milliseconds and you would store the last ms that the message left and subtract it from the current ms to get the distance in time.There is a very very very rare occasion here that the end time is < than the start time in which case you do this : (UINT_MAX-start_time+end_time)
5. If your distance in milliseconds since the last message is bigger than the limit in milliseconds you enforce then you send the next message from the Outbox
6. Instead of calling bot.SendMessage in the loop you now call Outbox.add_message_for_sending or something.
7. With a modification that also stores the chat ids you could also store where the message is going and that would be the solution for multiple users.

Thank you for replying. I will try your way

Hello mate. Great article. It works well for channels and groups and I have to make the bot an admin. But what if I want to send it to a personal telegram chat, how can I add the bot to a personal chat? Is that possible or must I send the messages to a channel? 

What do you think?

[Tam Jian Fung]

Never mind....

I found the answer by setting AsHTML flag to true...

bot.SendMessage(InpTelegramId,"<b>Balance: $10056.21</b>",true);

Sorry...

Hi, can u share the code on how to do that ? I am also searching for the code to make the Text Bolded and in Italic style and send to telegram server.

Hi everyone,

I am trying to send a message from MT5 to Telegram using a bot. However, I could not send the message from MT5 to Telegram due to the error: Error Code 400 Description "Bad request: chat not found"

Has anyone encountered the same problem? Can you give some reasons why this error might have occurred?

I did a lot of research online, but I could not get the right answers.

MT5 to Telegram Error: Error Code 400 Description "Bad request: chat not found"

Sir, thanks for your reply. Below is the full source code. It is just a simple expert advisor that extracts data from a text file and then attempts to send the data to a Telegram channel. However, it encountered the error mentioned.

Adding emoji in telegram messages.

Frédéric LEBRE, 2023.12.04 13:56

Hello, 

Please could you help me.

I try to send a message to telegram using emoji.

when emoji unicode is for example : U+2702 i use as string value " \x2702" and if works.

SendTelegramMessage(TelegramApiUrl, TelegramBotToken, ChatId, "\x2702");

But when unicode is like this : U+1F648 nothing works.

I included <Telegram.mqh> as i read in topics, but i do not know how to do more.

Thx for your answers.
