RSI Calculation – Need to Match My Results with Yours

[Oleg Folz]

Hello,

I’ve been working on integrating your RSI values into my analysis, and I’d like to make sure my own Excel calculations match what your service produces.

Could you please share:

1. The exact calculation method you use for RSI (e.g., Wilder’s smoothing method, SMA-based, or another variant).

2. The default lookback period (number of periods) your calculation is based on.

This will help me align my formulas with yours and ensure that the results are consistent across both sources. I appreciate your help in getting this right.

BR, Oleg

Hi Oleg,

We use an open source technical indicator library to provide the calculations: https://dotnet.stockindicators.dev/indicators/Rsi/#content

The code for the RSI calculation is here on GitHub: https://github.com/DaveSkender/Stock.Indicators/blob/v3/src/m-r/Rsi/Rsi.StaticSeries.cs

The default lookback period is 14 days.

Kind Regards,

Andrew Sinclair (Coderun Technologies)
