Comment on Introducing screener by Tickertape
Hemant, Check this link: https://kite.trade/docs/kite/#studies-indicators, takes you to the chartiq (international charting vendor for Kite) documentation on how all indicators are calculated. For RSI, I can see:
RSI = 100 – 100/(1 + RS)
RS = Average of the up closes over n-periods
Average of the down closes over n-periods
Vasanth, can maybe tell you the formula used on Screener. Btw, smallcase screener is an end of day screener, which means it updates only once every night. Kite indicators are live.
