Important Levels for 12-10-2021. If we open flat and cross 18015 levels, we can take longs for targets of 18038,18058 and 18090. SL can be kept at 17995. If we see a massive gap down, the next support zone will be from 17920-17940 and we can expect a bounce from these levels, we can enter longs if we see good +ve price action with volumes for targets of 17960,18000 and 18015 levels. SL should be of 20 points and trailed aggressively. Will avoid shorting the index unless we see levels below 17835. Option data shows good put addition at 18000 but still calls are dominating at 18000, so we cannot be extremely sure how the index is going to behave, but sustaining above 18000 for sometime and we can see another ATH tomorrow itself.
