The code doesn't work

Hello, I wrote a simple bot in Python that is also connected to a telegram bot and a channel, and I can’t understand why it doesn’t work. I receive messages about the top coin in terms of growth, the current price of the asset that I entered, but orders do not open, no matter how I try to correct something. Help me please. Here is a link to a repository with python code:

Could you please provide details about the error you encountered when attempting to place a new order?
