Bank Nifty: Harmonic Pattern

I think BNF should not sustain below 28800, in any case, if it will sustain then another 800-1000 points downside will open.
On the upside, supply zones are 29500-29550 \ 29750 \ 29900-29950.
VIX trading above 24 so both sides moment is possible. Its difficult trade with small stop loss.
