Gaining from the stock market can be achieved by understanding the percentage gain formula. This formula is used to calculate the amount of money gained when trading in the Forex market. The formula is based on the price of an asset multiplied by the percentage of gain and then subtracting the initial purchase price. The result then shows the exact gain for a successful trade and the total sum of profit when subtracting the costs of the trade. To understand how this formula works and to successfully make a profit from the stock market, traders should get familiarized with the formula and practice with it.
