We have looked into this issue extensively and have found the reason for the difference between trading view Stochastic RSI and ours.
The K value on trading view is by default 3, while our default is 20. We have this default based on past performance and professional trading advice. Another reason why the number might be off is that the MA for SRSI is not configurable on trading view, but it is configurable on Cryptohopper.
The difference between the values in these parameters and the parameters on trading view cause the difference in the final value. We have extensively checked if our numbers and tradingview's numbers are the same if we set these parameters to be the same, and we have been able to confirm this.
