I think I'll add Cryptsy and Bitfines in v1.07.96
This features you tell is planted to Qt Open Trader
And currently multi exchange and multi currencies monitoring is not supported.
You say multi-exchange is not supported, and I can see what you mean with that.
I do not currently need or have accounts with more than 1 of the supported exchanges to test this, but it seems to allow for running multiple instances of itself, at least on Linux.. Is that not the case? I can run one and log into BTC-e, then run again, and the login screen pops up.
As for multi-currency monitoring, will this be supported in the future? I'd never have thought about it before using the script that I do, honestly, but it might be nice to have the ability to check if another path to same resulting investment (via another currency trade) would result in better ROI. Not a necessity, by any means, but of potential value...
Multi-currency monitoring and also multi-exchange monitoring will be added to Qt Open Trader.
If you want to start many program instances to use multi currencies monitoring with same exchange, make sure you use dedicated API keys for each instance.
