How to calculate the profit and loss of rebar futures?
The actual profit-loss ratio of rebar futures is the market fluctuation multiplied by the leverage ratio, in which the leverage ratio is the reciprocal of the margin ratio. For example, if investors open more orders, the margin ratio is 5%, and rebar futures rise by 2% at some time after opening positions, then the investor's profit will account for 2%×20=40% of the opening funds at this time. If it falls by 2%, it will lose 40%. If the decline is equal to the margin ratio, investors will lose all the funds for opening positions.
The above is the calculation method of profit and loss of rebar futures. In fact, all futures can be calculated according to this method. Therefore, futures is an asset with relatively high investment risk, and the margin ratio is one of the keys to determine the futures risk.
