The problem is that the tick value of the Bitmex XBT contract is no a fixed value the orders size to open trades are in $ , but the profit/loss is in XBT A 100.000$ order at a Bitcoin price of 10.000$ = 10 XBT but a 100.000$ order at a bitcoin price of 5000$ = 20 XBT therefor the tickvalue of XBT changes as the price goes up o down the formula is = Contracts * (1/entryPrice - 1/exitPrice) see screenshot for the current tick value ( that's per 1 USD, so you have to devide that value by 2 , since the minimum ticksize of the XBT contract =0.5) one other minor problem to calculate the correct profit/loss is that market orders (takers) suffer a 0.075% fee (on the $ contract value of the order) while limit orders ( makers) get paid 0.025% rebate |
