nifty weekly technicals

just have a look at the nifty weekly chart. red and pink lines are resistance lines and green and blue lines are acting as support lines. it is very clear that earlier, the shorting opportunities were available on break on downside from these lines and shorts covered on the strong blue support line at bottom(approx 4000) and nifty bounced on short covering and some buying there. now it is above the green line(approx 4230) and upmove is now resisted by the pink resistance line which comes in the region of 4525-4534 in the coming week. If the pink line is also taken off then the red line provides resistance above 4600. chartically, the support can be provided at/near 4300(not shown) and also by the green line. a nice short strangle strategy can be worked out here.
