My observation
BankNifty (spot levels)
BN if crosses and sustains (each level), then can move in following levels
12535/40 -> 12570/80
12585/90 -> 12620/25 ->
12650/60
And if crosses this level also, then
Celebrate a party
Initial SL should be 12460/80, that can be trailed as per ones risk
Take care
