Why pin bar doesn't give results sometimes?

Asalam-o-alikum! Dear members aksar ap nay note kia ho ga kay market 1H ya 4H main pin baar bnaati hay aur phir us kay baad us kay mutabik move nahi karti. Balkay us kay ulat bht zayda move kar jaati ha. Esa kun hota ha?

Bhai yeah forex market hai yahan per market kisi indicator ya kisi order ko follow ker ky move nehi kerti yeah just candle stick pattern main patterns banty rehty hain ky kabhi koi pattern tou kabhi koi aur yeah hoty bhi post movement per banty hain lekin koi aik pattern next movement ko indicate nehi ker sakta just kuch candle aesi banti hain ky market ki next movement aik hi direction main hoti hai lekin all the time aesa hota bhi nehi hai
