Fibonacci Levels
Sorry for the delay. I was busy at work and I do not have access to traderji at office.
It is not tried and tested, but I sometimes use this technique to see where this price goes.
For your question on how I started at 2281, that is the nearest deep correction that has happened in nifty on its trend upward.
For your question on how I arrived at 8169, I use the Fibonacci tool and drag the tool where the levels are closely considering all the consolidation candles. If you notice when I consider one consolidation level at 4850, the other level got automatically adjusted at 6920. So I stopped dragging and the last level I see at 100% is 8169.
