I need a coded trading strategy that spots a classic Bollinger Band squeeze on a 1-day chart for stocks and then triggers a long or short entry the moment price breaks outside the bands. Here is how I picture it working: • During consolidation the upper and lower bands converge to a user-defined percentage width, confirming the squeeze. • Once price closes outside the band, the system generates an immediate buy (if above) or sell (if below) signal, with optional stop-loss at the opposite band and a trailing take-profit. • I’d like clear visual markers on the chart plus pop-up/email/push alerts. • Please include parameters so I can adjust band length, standard deviations, squeeze threshold, and alert style, as well as back-test results that show historical win rate, drawdown, and basic performance metrics on a broad stock watch-list. I’m flexible on the exact coding environment; choose whichever platform lets you deliver a reliable, easy-to-tweak solution and provide the finished script with brief usage instructions. Scan would be for entire NSE stocks I want the system to be on pc and run the triggers which i can see on my pc and mobile
