The market reached very close to 21-day EMA (exponential moving average placed at 21,947) after more than one percent correction seen on February 28. Hence, all eyes are on the monthly expiry day for futures and options contracts on February 29. If the index manages to defend 21,950, then it may face resistance at 22,000-22,100, but in case of a breakdown, the index may correct up to 21,800.
