stock has given weekly close exactly around dynamic support area, 149-150. In the past it has faced resistance at this area for weeks long, so in the downturn it must give support. Short position to be taken only after a daily close below 148, even in that condition we must remember that a weekly close necessary for further down move. As this is the expiry week it might confuse. But pattern saying that it must complete 5th wave to complete ABCDE pattern at the support trendline after which a nice uptrend can be obtained. Right now more chances are that to make a profit sell below 148 daily close for a target of 140.
