1. MACD negative crossover on daily and weekly time frame which is going towards zero line.
2. RSI is at 47 which can be considered week.
3. Small support at 21860.
So keeping in veiw of above mentioned factors, watch levels 21860 closely, if these levels broken then sharp fall can be expected towards next support which is 21400. In next two weeks, strong posibility that these two support can be broken and nifty can go upto 21000 and 20300 levels.
So, one can trade 22000 put option Mar or Apr series or one can look for 21000 put option Apr expiry for hedging of holding stocks.
