I can only close orders via market pricing, and it is incredibly frustrating to see that I will close in profit (to the tune of $250ish) then close the order at market pricing (CSGO at $88 with an entry at $90.28) only to have it close at $93+ and my PnL reflect a loss of $300+

And +1 of having the earned funding reflected in the PnL / total account value. I closed a short on GAVIN with $500+ in profit but also had over $3100 in funding for being paid to take the short side only to have $0 of that value transferred over to my account.
