Example

         You want to take a 100000 position in BTCZ19, 
         when it is trading at $10000.

         Let IM = 5% and MM = 3%

         BTC Value of position in BTCZ19 = 10000/100000 = 0.1 BTC

         IM = 5% of 0.1 = 0.005 BTC
         MM = 3% of 0.1 = 0.003 BTC

         Suppose the price of BTCZ19 when you decide to exit 
         is $12000, then

         PnL = [1/Entry Price - 1/Exit Price] * No. of Contracts 
         = [1/10000 - 1/12000] * 100000 = 1.66666667

         Net Profit = PnL-IM = 1.66666667 - 0.005 = 1.66166667

         Net profit in USD = 1.66166667 * 12000 = $19940
