Scanning for RSI (9) Interval Quarterly

tempestlight

I know you can do monthly RSI scans ([monthly rsi(9) < 30]) as an example, however i really want to do quarterly interval scans but the quarterly option is not available in stockcharts. Is there any sort of code i can do that could replicate and find RSI (9) that are signalling say 30 on a quarterly interval instead of a monthly interval?

I'm just guessing, but quarterly is 3 times monthly, so you could try monthly rsi(27).

It won't be the same because quarterly rsi(9) would use only 9 periods of data (the quarterly closes), and so would be comparing different values, but the rsi(27) incorporates some of the same data and the differences month to month over 3 months might cancel themselves out so they acceptably approximate the quarterly.

You just have to try it and see. The rsi(27) line will be smoother (because the increments month to month are likely to be smaller than quarter to quarter, most of the time), and might be more 'accurate'.

There was a similar question posed a while back on the forum with a couple ideas. It's tough to be exact with alternate periods not supported by the scan engine but there are usually ways to get in the ballpark.
