i'm looking to perform screens in different time periods for RSI. every software tool has RSI 14; however, i'm looking to do some testing for other lengths of time, and have a screen for that. ie. RSI(2)>75 or RSI(7)<25 i have tradestation, but can't find it intuitively there (i might have missed it). i know it is in realtick, but that's not a screening system. anyone have any suggestions / alternatives? thanks.
i am not sure a) what you're testing b) why and c) how familiar you are with rsi. all i can tell you is that there's been exhaustive testing done on the issue of choice of periods and 14 has always come up as the "optimal" number of periods. obviously one is free to "test" and use what they like.
