How to calculate n days ago RSI(3)?
It should be RSI( ? , 3) , but I have to create a numericseries from Low[3] to Low[5]. Am I right? But how to calculate that numericseries?
Thanks,
Raymond

the correct answer will depend on the time frame you are working on.
In general you can back reference variables or functions similar to what you can do with some reserved words for accessing previous bar's values.
Having said that you could store the value of the RSI function in a variable and use the variable for accessing previous bar's values.
Now vRSI[3] would provide the value of the RSI three bars ago.
Alternative you can back reference the function directly or use it with Close[3] as price, but the above appears to be more versatile especially when you intend to use multiple different lock backs within the same code.
