The Flag pattern as seen is generally considered to be a continuation trend. So a Buy will only be triggered post breakout of the trendline.
Looks like a downward movement. I have initiated trade at 71.1075 Mar futures. Let's see how this one goes. Mar futures since the feb expiry is near and i don't think the downside tgt will be reached in coming few days.
So i closed my shorts at cost. And entered new lomgs post breaking 72.25 for the next target of 74.5.
