Gangadharan,
First of all, good work on spotting the pattern.
Now coming to trades. It is one thing to spot a pattern and another thing to trade it profitably. The neckline according to your chart is 344. DLF now has sold off nearly 12% in two days and markets have corrected 800 points. Now given the fact that we are still in Bull market, the chances of markets bouncing back are far more. Hence, DLF could bounce 3-4% in the next 1-2 sessions. This would take the counter to 337 - 338 price levels following which you could have initiated fresh shorts with the neckline level as stop loss. This would have given you a better risk to reward to trade with.
