In CAT 4.6 there seems to be a bug, in BTC markets at least, where an old order keeps getting reloaded as a new one during every refresh:
Not sure to have understand what the problem is. If you have a log please send me.
EDIT: taking a fast look at your logs there's a moment where CAT stop making actions (at the end of market log) but your 85 USDT seems legit. Gain on this market is in USDT not BTC.
The $85 is definitely incorrect. I checked and the profit is only $0.28. The cumulative sum $85 is because the same orders keep getting loaded back into CAT every 40 s.
