The FV formula is a widely-used tool in the Forex trading world. It was developed by the Chinese mathematician Zhao Junfu to help traders calculate how much money they can earn given a certain investment. This formula takes into account the current exchange rate between two currencies, as well as the rate of change in the exchange rate over time. The formula is quite simple, and helps traders maximize their returns while minimizing their risks. Since its emergence, the FV formula has become an integral part of the Forex trading world, helping traders analyze and capitalize on Forex market movements.
