Pl. help me in calculating the profit/loss and stop loss of my strategy.

I have derived a formula which works 90% of time in nifty.

I calculate 2 levels everyday in which if the 1st hits then the 2nd hits 90% of time.

But my concern is the remaining 10% of miss should not eat my 90% profit.

My per day profit is 10 points.

Senior members pl. guide me whether this strategy shall give any profit at the end of 100th day.

Thanks
