Nifty Important Level's.

If the Nifty opens with a gap down of 100 points, the immediate support level is likely to be 17430. A support level is a level in the market where there is a significant amount of buying pressure, which can make it difficult for prices to fall further. If the price reaches 17430 and stays there or bounces back up, it is likely to be a good buying opportunity.

However, if the Nifty cannot sustain 17430, the next support level is likely to be 17300. This means that if the price falls below 17430 and continues to drop, it is likely to find some support at 17300.
