FYI, I'm using C.A.T. 4.6 and I'm still seeing trades on Poloniex being calculated incorrectly.  For example, I buy 0.80 BTC worth of Qora at 10 satoshi's using CAT (8000000.00000000 qora).  Fee is 0.15%, which is 12,000 qora.  However, CAT leaves behind 0.1 % or 8,000 qora.  These  are not sold at 11 satoshis.  Instead, only 7980000 are sold, 8,000 fewer than should have been.  

Is the Poloniex API returning the wrong fee or is CAT still hard-coded for 0.25% for Poloniex for all trades?
