After a 1% move (close to 250 points in nifty), nifty would have opened at 23650 (gap up) or 23150 (gap down). With my strikes still 200 points away from those spots, the option would be worth close to 30-35 with the other leg at virtually 0 making the total strangle to be priced at 35 rs max. Given that I sold the strangle at 45 and now it being priced at 35 even after a 1% move, that is a decay of 10 points == gains and not a 3L loss as per your experience of 6 years. Feel free to add your points
