This is my explanation of where I think you saw as wrong

My SLM/USDT PREP had two sells even with my order set. The order was set such that it would be executed when the price is ≤3.0380. the order details can be seen below

As you can see the sell was split into two and so I had two sells orders for that trade. I indicated this in my post.

Because of this, I made the input for that trade :
SLM/USDT PREP, Buy, 3.0220, 3.0340, 3.0330, +0.1680, +0.0.495

This was to show that the profits and sells were two.

This has happened with not just this week's trading contest. @pelon53 and @abdu.navi03 can testify.
