TradingView webhook alerts to Telegram + chart screenshot

Telegram chat https://t.me/hbalerts In the chat you can discuss the service and test alerts. The chat will receive service messages from the bot (error log).

Webhook alerts work instantly, with no delay. The message is sent to Telegram right away. In the alert text you can pass live data https://www.tradingview.com/blog/en/introducing-variables-in-alerts-14880 (the link shows an example of how you can configure the message for yourself) at the moment the alert fires.

Instructions

Start a chat with the bots: @hamsterhookbot and @hamsterhook_bot (the second bot is a backup, since the first one is already hitting its own limits). Use the bot @fetch_id_bot to get the id of the chat the bot should send notifications to. If it's a group chat or a channel, the bot must have permission to send messages. To get a channel id - forward any message from the channel to the bot @fetch_id_bot. Chat and channel ids start with a minus sign "-".
In TradingView create an alert.
Enter the webhook URL http://164.68.120.166/alert or https://hamster-bot.com/alert.
Enter the message in the required format.
