Personal opinion. I think BN is close to a big fall as it has almost touched the 0.618 fib level of the complete down move from ATH. Expiry is also close. Let's see what happens. Expecting BN to come down to 37000 area within the next 3 sessions.
Personal opinion for 11/01 . BN is expected to open slight gap down to flat. Chart shows 38100 as a good intraday support supported by trendline and key moving averages. Even if BN opens down, it is good to stay bullish as long as 37800 is not breached. I expect BN to go above 38600.
My personal view on banknifty. I don't think banknifty is likely to close above 38800 to 38900 within a couple of weeks instead my speculation is that it is going to trade in between 34900 to 38900 for a few upcoming sessions.
