1 - Yes, i think 0.00000 is only a visualization problem, there are other number after the 5th zero : ex 0.00000XXX
So why does C.A.T. try to place a BUY order for 0.1 EUR having only 0.00000X USD?
2 - You need to check the % Gain from the Gain Tabs. As i said sometimes you could set 0.5 % Gain, but due to rounding routines have for example 0.45%
You can see the % GAIN in the pic I posted. It's > 0.5%. So why does the total gain go down?
EDIT: I found the reason. I didn't sort by TimeStamp.
