Actually i think you are able to create any rule with the Limit Editor.
So how can I make the rule
Mode->Price Limit-> Never *PING *OVER *TopOfCurrentOrderBook Price *MINUS *0.5%
CAT show the Available amount. But you can't be sure that it's the real available amount.
Could you please add an overview where we can see what C.A.T. thinks is in the portfolio?
So when I start with USD/BTC -> Ping SELL 100 USD, then C.A.T. would have 100 USD and 0 BTC in its pingpong portfolio, and after several pingpong trades we could look the stats and it would show 101 USD and 0.0001 BTC or so. That way we could verify whether C.A.T. works properly.
Probably you have the option ALWAYS ADEQUATE QTY TO MIN QTY (If Needed).
Yes, C.A.T. tries to place orders of 0.0000 quantity and then rounds them up to 0.1. Doesn't seem a good practice.
