Short Stock Profit Calculation

[jackyjacky135]

Hi, I have a problem regarding calculation of short stock profit. I have set max position size per trade is 10% of total equity and the commission percent as 0.2. From the following photo, I calculate the profit as
((35.761 - 36.409) * 2796) - (99987.76 * 0.2%) - (99987.76 * 0.2%) = -2211.75904

But the actual result in the following is -2215.38. Anyone knows where I went wrong? Thanks.

This is my currrent setting for shorting the stock

99987.76 * 0.2%

Why did you calculate two times with 99987.76 * 0.2%? The market value of the open and the close should be different (((35.761 - 36.409) * 2796) - (36.409 *2796 * 0.2%) - (99987.76 * 0.2%)).
