I got the error code ... from the exchange. What does it mean?

In the live mode you might face certain error codes you don't understand and that aren't documented in Jesse's docs. Luckily Binance has a list with an explanation for all error codes that might get returned during live trading: https://binance-docs.github.io/apidocs/spot/en/#error-codes

If you still aren't sure what it means head to our Discord and ask there.
