This is a different version of Stochastic RSI . the only difference is the use of variable moving average by Lazybear instead of regular sma for K smoothing.

Its purely an experiment. I am not a professional trader but an enthusiastic programmer trying different indicator combination to see different results.

Criticizing and negative comments will be gracefully accepted. :)
Appreciation will be even more. :)
