The Market Facilitation Index, also known as MFI, is a popular MetaTrader 4 indicator developed by Bill Williams, the author of Trading Chaos. This tool measures the relationship between price movement and trading volume, helping traders evaluate the strength of a trend and potential reversals.
Unlike traditional volume indicators, the MFI shows whether price movement is supported by strong participation or if momentum is fading. By using a simple histogram with color-coded bars, it makes trend analysis faster and easier. The MFI Indicator for MT4 is free to download and can be applied across different trading styles, from scalping to swing trading.
How the Market Facilitation Index MT4 Indicator Works
The Market Facilitation Index is calculated using the following formula:
MFI = (High – Low) / Volume
-
High: The highest price of the candle
-
Low: The lowest price of the candle
-
Volume: The tick trading volume
This formula measures how much price moves compared to the volume traded. The results are displayed as histogram bars, with colors that signal the current market condition.
MFI Color Signals in MT4
-
Green Bar: Volume is rising and the trend is gaining strength. This often confirms that the current move will continue, but it is not always an entry point since the trend may already be established.
-
Brown Bar: Momentum is fading and interest is decreasing. This suggests sideways conditions or a pause in the trend.
-
Blue Bar: Price is moving but without strong trading activity. This creates uncertainty and increases the chance of sudden changes.
-
Pink Bar: Both buyers and sellers are active, which often signals a potential reversal. Many traders consider pink bars the most important MFI signals.
Trading Strategies with the MFI MT4 Indicator
The Market Facilitation Index is especially useful for detecting reversals and validating strong moves. Traders often use the pink bar as a primary setup for breakout or reversal strategies.

Target a profit 2 to 3 times greater than the stop-loss or near the next resistance level.
Sell Setup with the MFI

Wait for a pink bar to appear.

Place a pending sell stop order a few pips below the most recent low.
