Hello,
I used same data source in IB platform (TWS), Multicharts.NET 8.7 and latest SC. Apparently the problem is with SC. RSI (14) looks same in Multichart and TWS. In SC it is too fast moving for such long period.
Sorry for my mistake. TWS showed who is doing correct RSI

Multicharts.NET RSI(7) is equivalent to RSI(14) in other software like SC. Something wrong with code?

I have changed a bit RSI code, so it now draws not just RSI line but also exp. moving average of RSI line. You can specify EMA period in length2 setting. Default is 3. I think that many users will like it.

OK, I managed to do myself. I will try to attach .pln file here or to Contribution area. Indicator shows RSI and EMA3 from RSI. You can change EMA period to something else.

Why Multicharts.NET doesn't contain also average line of RSI calculated as EMA/SMA from RSI line? Most software has this average RSI line. How can I get it on my graph? NET version is totally different language than I was used to. Any help please?
