Compute RSI

[Maxf]

Hi,

I'm trying to compute RSI values using the formula found on the IG website. (RSI = 100 – 100 / (1 + RS)). But I can't get the same result as seen on the IG website chart. For the average gains over x periods / average losses over x periods, I tried simple average, exponential average, and SMMA (simple or modified moving average). Using SMMA I was able to get the most approximative values, but still not the values seen on the IG website chart.

Does anyone have the solution to this problem?

Thank you in advance for your answers.

Reminder:

RSI = 100 – 100 / (1 + RS)

Where RS is the average gains over x periods / average losses over x periods

Hi everyone,

I am attempting to achieve the same results, but consistently encounter a 5 to 10% discrepancy compared to what IG calculates.

I would appreciate any assistance or insights on this matter.

Best wishes,
