Do big institutions make candlestick patterns to trap retail investors?

I feel this many times, especially while seeing stock recommendations from firms like Motilal Oswal or ICICI Securities. Like recently, they entered Cipla at ₹1529, and then it fell to ₹1450 levels, they suddenly gave buy recommendation. It looks like these patterns are made to tempt retail investors to enter, especially when DIIs are sitting on losses because their moves went wrong. Are retail traders being fooled into predictable entries and exits so big players can recover their losses? What you all think?
