I'm trading live on Bitfinex.  However, would like to trade about 5 agorithms on the same account (trading same symbols).  My problem as an obvious one.  How does each strategy trade as if they were trading their own account ?  How do you isolate them?  Is there any way of doing this with QC logic ?  I would understand it's possible to keep track of each order individually in the code by storing order id's and amounts in lists, But, if the server fails and the memory is lost then everything will be haywire.  Is it possible to store the data on-disk ?  Not sure what the limitations are of the QC serverse.
