Hello, I'm new in this forum and I would like learn and try to help other people.

I have a qüestion about stoch RSI because usually investing in actions I'm using 14, 14, 3, 3 periods but I think with bitcoins (or similar) the periods should be shorter.
 
A lot of times the Stoch RSI indicates overbought early and reduces a big quantity of profits if I close the position.

Which periods recomends use with this indicator investing in bitcoins or other altcoins?

Thanks!
