Hello -

Has anyone created an indicator that calculates Upside/Downside Deviation?

i.e. Stdev of days(bars) when the market is up?
i.e. Stdev of days(bars) when the market is down?

It seems to me I recall a function that could be used with StDev what would only use bars given a certain criteria. Can someone help point this out or give suggestions?

Thanks,
