Parameters

s

The financial series where the first element is the traded price on the most recent period, the second element is the traded price of the previous periods and so on, for the asset under consideration.

Evaluation

The formula for the calculation of MFI is:
MFI = (high - low)/volume
where high is the highest traded price during the period, low is the lowest traded price during the period and, volume is the overall volume traded on that period.

Interpretation

There are four types of trading sessions called:

1. Fakes - volume is low but MFI is rising
2. Fades - both volume and MFI is down (the price might move in the opposite direction)
3. Squats - the volume is up, MFI is down
4. Greens - when the MFI and volume are up which represent a strong signal to follow the trendline
