This one is Ascending Broadening Wedge
here in Banknifty
and time is not ripe for its breakout yet, probably up side trendline needs to redrawn depending on todays close ( if positive ) but this is not yet ready for breakout. So go on 15mins in Banknifty
and find trade setups to take trading decisions.
For expiry, will post out range by 2mrw, yet to do that part !
I will post it out or update when its on verge of breakout !
