If in the bot log file you see the error that the bot does not exist, that means that the signal that you are sending from TradingView does not match with any of your bots.

This error can occur if you have a typo in your TradingView alert comment or you changed the bot settings and did not update the TradingView alert.

To fix the issue, please delete the TradingView alert for the bot and create the new one using the TradingView alert comments from the bot settings tab.
