Why not use TD setup for trend trading in direction of 100 sma ?
Currently it's sloping down. You get a TD setup. Short the market and put a stop at the high plus the range of the biggest bar in the setup.
I had a visual look at NIFTY chart and found some setups like that which worked very well.
I don't think absolute levels of spot open matter, the move is already priced in the futures, and hence in the NF. IMO, what spot does after open is relevant.
Here just for educational purpose a little update on this. If some one would have implemented a "Long Straddle" at the black horizontal line with for example 7500 put and call, he could protect around the down trend line his call leg by adding a short 7600 call and now wait for confirmation until a new move up will come. Until then the call leg is safe and the put leg can work.
Nifty is very reluctant to go up. FTSE has spiked 50 points while Nifty around 30. Usually it's the other way around, small movement in FTSE makes Nifty crazy.
