Important Levels for 30-12-2021. An uneventful day although fast execution in the morning did give us our entry and our targets. Tomorrow being the expiry, and the index still in range we can expect wild movements in either side. Will avoid to trade inside the range of last couple of sessions (17160-17280) and take trades once this range is broken. If we open flat or with a small gap down, and start trading below 17170, we can take shorts for targets of 17125,17065 and 17040. Option data indicates bearishness.
