Longest Sequences

I was interested in the below questions from long time

1. If Nifty falls or goes up for how many days it keeps on moving in the same direction. What kind of distribution that data follows?
2. What is the %age change which happens in one move?

I was interested in this because if we are buying or selling options it can help us to know for how long to keep the position open from time and %age move perspective.

So i did some analysis and below are the findings for the same at the weekly and daily level.
