Yesterday couldnot sustain above 20018 Today's opening is improtant:
If open above 20969-20900 and after taking support able to break and sustain above 21018-21025 with 15 minute goood closing, then intraday upside move can be seen to 21096/21106.
If open gap up above 21018-21025 will wait for buying setup if sustain above 21018-21025
Downside support remains 20940-20900, 20827-20830(can act as major support) have to wait for price action for long opportunity ,if price approaches downside to 20827/20830
