Market Facilitation Index

he Market Facilitation Index (MFI) is a technical indicator that is used to measure the strength of a market’s trend. It calculates the change in price and volume, and is intended to indicate the amount of buying and selling pressure in the market. The MFI is calculated by taking the difference between the high and low price for a given period, and dividing it by the volume for the same period. It is typically used in conjunction with other indicators to help traders identify potential trading opportunities
