Market Facilitation Index
creator: Bill Williams
It's from MT4 built-in indicators.
Market Facilitation Index technical indicator (BW MFI) is the indicator which shows the change of price for one tick.
Absolute values of the indicator do not mean anything as they are, only indicator changes have sense. Bill Williams emphasizes the interchanging of MFI and volume:
Market Facilitation Index increases and volume increases - this points out that:
a) the number of players coming into the market increases (volume increases);
b) the new coming players open positions in the direction of bar development, i.e., the movement has begun and picks up speed.
Market Facilitation Index falls and volume falls. It means the market participants are not interested anymore;
Market Facilitation Index increases, but the volume falls. It is most likely, that the market is not supported with the volume from clients, and the price is changing due to traders (brokers and dealers) "on the floor" speculations;
Market Facilitation Index falls, but the volume increases. There is a battle between bulls and bears, characterized by a large sell and buy volume, but the price is not changing significantly since the forces are equal. One of the contending parties (buyers vs. sellers) will eventually win the battle. Usually, the break of such a bar lets you know if this bar determines the continuation of the trend or annuls the trend. Bill Williams calls such bar "curtsying".

Calculation:
To calculate Market Facilitation Index you need to subtract the lowest bar price from the highest bar price and divide it by the volume.
BW MFI = (HIGH - LOW) / VOLUME
where:
HIGH - maximum price of the current bar;
LOW - minimum price of the current bar;
VOLUME - volume of the current bar.
The four possible groupings of MFI and volume were termed Green, Fade, Fake and Squat by Williams.
Green: The MFI increases and the volume increases. This means that the number of participants entering the market increases, therefore the volume increases and the fresh incoming players align their positions in the direction of candlestick growth. Notice the long solid candles in the candlestick chart which indicates that the trend has begun and is picking up speed.
Brown Fade: The MFI falls and volume falls. It means that the market participants are indifferent and the price movement is small on small volumes. This usually happens at the end of a trend.
Blue Fake: The MFI increases, but the volume falls. It is highly likely that the market is being supported by broker speculation and not any significant client volume.
Pink Squat: The MFI falls, but the volume increases. In this particular situation bulls and bears are fighting between themselves to see who will dominate the next trend. These battles are noticeable by the large sell and buy volumes. However, the price does not change appreciably since the strengths are equal. One of the competing parties either the buyers or the sellers will ultimately triumph in the battle. Usually, the fracture of a candle at such a point indicates either the continuation or termination of the trend.
