FORCE INDEX - how to rank

Unfortunately, Force Index is not a "normalized" indicator, meaning indicator values across different stocks cannot be compared in a meaningful way.

Possibly you could normalize values by expressing the current reading as a per cent of a moving average of Force, for instance

rank by [Force(21)/sma(21, Force(21))]

But, I'm not sure how that would work because Force can generate positive and negative values. Dividing a negative by a negative gives you a positive, but you wouldn't want to rank a symbol with extreme negative Force and MA next to a symbol with extreme positive Force and MA. You would want those at opposite ends of the ranking.


So, another possibility is Force divided by average volume.

rank by [Force(21)/sma(21, volume)]

This does seem to rank symbols in a more meaningful way - big positive Force values are near the top of the ranking and negative near the bottom. But, you can get symbols with high positive values where Force is falling from even higher Force values ranking next to symbols with high positive values where Force is climbing from lower values, and those are different technical situations.

But, maybe you can deal with that in the scan by requiring current Force to be greater than x days ago Force, etc., or whatever other characteristics you are looking for. For instance:

[group is sp100]

and [Force(21) > 0]

and [Force(21) = max(5, Force(21))]

// or you could do something like
// and [Force(21) > 5 days ago Force(21)]

rank by [Force(21)/sma(21, volume)]
