It is simply your traditional MFI, except that your 50 line became the actual price.
Why and how could it be useful? This indicator helps to spot more easily and efficiently divergences.
You could also use it for trend reversals as you usually do with your 50 line, but I would suggest to set a higher length for the MFI, like 155 or something like that.
