yes, the Quatloo-Trader 2 has to be updated for poloniex, they changed their API-calls when they added the margin-markets. It should work fine for Bittrex, both the versions - but to trade #steem & #sbd you only really need Quatloo-Trader 1
If the post gets a lot of upvotes I´ll send some of it to Markus to hurry him up and get him on Steemit as well.
He is a great guy
