The calculation method of spot crude oil is based on the leverage ratio of your trading variety, and the total profit-price difference-import and export fee = net profit. If there is an extension, the extension fee will be deducted, which is generally around 22 thousand. Profit formula of spot crude oil: profit point * specification * number of lots-handling fee-spread.

I take 100t crude oil as an example. If you buy 100t crude oil now, the current price is 2800, and you close your position at 2850, then your profit on this order is 50 points, that is, (2850-2800)* 100* 1.
