Wrong "symbol" Binance Api

Question

I am trying to make a simple Trading bot to trade on Binance.

When the bot trys to place an order it doesn't go through and I get the following error: "BinanceAPIException: APIError(code=-1121): Invalid symbol."

As far as I can tell I have the correct ticker for Ethereum and USDT. I have been trying to find an answer for hours, but can't find anything that helps.

Thanks for your help in advance,

Please see the code below.

The error is on this line TRADE_SYMBOL = 'ETHUSD'. You need to change it to ETHUSDT
