Bitstamp Live Trading Issue

[jzay]

I am unable to run the live trading for catalyst through Bitstamp. I was able to get it working on other exchanges but, have been receiving errors presumably from CCXT when trying to run live with Bitstamp. I was told this is potentially a problem with the catalyst wrapper around CCXT and to post my error here for further analysis. Thanks the error is below.

Catalyst currently supports these exchanges. We hope to add more exchanges (which are supported by ccxt) in the near future.

@AvishaiW Could you point me in the right direction for how I could fix the Bitstamp data to work with catalyst? Does each exchange require a different implementation even though your are using the CCXT library?
