Complaining needing clarity

Good evening

I will like to ask, I’m experiencing bad situation I placed a trade on boom 1000 as sell and I made little only to realize that the more my profit goes up my balance is reducing so I decided to close because I don’t understand what’s wrong. I have attached the picture below it tells me about swap so I don’t understand can you please clarify me here

I have a problem here,i placed a buy order and you guys placed sell and I’m on minus 37$ and there was no spike. Guys stop with the nonsense :rage::rage::rage:
