A cryptocurrency arbitrage framework implemented with ccxt and cplex. It can be used to monitor multiple exchanges, find a multi-lateral arbitrage path which maximizes rate of return, calculate the optimal trading amount for each pair in the path given flexible constraints, and execute trades with multi-threading implemenation.

Process finished with exit code 1

I am getting the above errors when running the code.

  1. Can someone help my getting this running? This tuple FutureWarning at the beginning seem to not affect the result. How can i avoid this error in the code?
  2. why do get 'NoneType' object has no attribute 'get_values'?

Would appreciate any help to get this running. Thank you
