Re: Please help to understand cash changes

I also met this question,but my question is not this day,it it close the position. on the open day,if you exchange future,you can see it easily.

your value is your cash and your position value.

you sell at 2615,comm is 2.615,close price is 2609,so you profit (2615-2609)10=60,your first cash is 20000000-2353.5-2.615=19997643.885,your end cash is 19997643.885+60=19997703.885 , your position value is 260910*0.09= 2348.1
ok,your value is 20000051.985000003
