Nifty - Over bought for a while now

NIFTY has been making new highs everyday. How ever its over bought for a while now. A rally from 10800-13500 has been phenominal. with almost all Nifty stocks above 200 DMA. How ever its not a very comfortable position to be in with a daily high. I would now look to book profits, keep trailing stop loss in all my positions. A fall upto 13000-12800 would be good (can be more). Look at selling below 13300-13350. Upside the market can get stretched as long FII buying continues.
