Nifty: 15 months. Weekly virgin CPRs. Price reacted.Nifty 50 IndexNSE:NIFTYVishwajeeth_JKWeekly CPR, plotted only where it stayed virgin. Untouched in the week it formed, so each box runs forward until price finally comes back and reaches it. The circles are the touches. Fifteen months on one chart, and the pattern holds throughout. September, 24,450. Price came down into the wide band and turned. That low is where the October to December advance started. October, 24,650. Reached, rejected, and price went from there to 26,250 without a meaningful pullback. December, 25,850. Price ran up into the box and stalled. That is where the advance topped out and started rolling over. February is the cleanest cluster on the chart. The long upper wick pushed into the 25,850 zone and got rejected. On the way down price stopped at 24,650 and bounced. Then it reached the wide 24,250 band and paused there before March broke it. Three CPRs, three reactions, one month. April, 24,550. The rally off the low ran straight into the box and reversed. That high held for two months. June and August, 24,250 again. Two more touches, two more turns lower. The August one is the swing high that started this current leg down. Seven zones, seven reactions. That is the whole reason to keep these on the chart. Now the right edge. The box that formed in early July around 23,500 stayed virgin through all the July and August chop. Price walked into it this week and is at 23,490. First CPR test since August, and the only open level below. Two untested ones sit overhead near 24,250 and 24,400 from the last fortnight. And the big March zone at 25,450 has now gone six months without a touch, still the largest unfinished magnet on the board. So the read is straightforward. Price is on a level that has produced a turn every other time one has been reached. Hold it and the first targets are those two small boxes at 24,250 to 24,400. Lose it and there is nothing open underneath until the March lows near 23,150 and then the April low at 22,150. I do not need a forecast. The levels were drawn weeks and months ago, price has come to this one, and the reaction here is the trade. Stop goes just under the zone. Not a recommendation, just sharing what I am watching.
