While Yesterday the 5500Ce, 5600CE and 5700CE had more or less the same OI. Today you can see the 5500CE being added the Positions and is slowly standing out. If you see the market moving down you will see more positions being added to 5500CE and so 5500 would act as the Strong Resistance for any Longs. Same case with 5300. 5300 Will not be broken easily. As told in the beginning of the series, Market will only play this 5300-5500 See Saw for some time before breaking out. That also means there would be some volatility.
