Nifty holds on to 2860 & gains too, keeping the uptrend intact.

Now "2860" becomes 5 Day Low too & need to be protected by Bulls. Upside resistances are at 3050, 3075. Supports below 2860 are 2780, 2750.

I have reproduced the Nifty intra chart of today with critical levels we had in mind & the possible trades based on the SAR & also the "15 minute range break out" that helped in the trade.
You need to use different strategies at different times and diff. styles suits for individuals.
You need to take in various views while trading which might help you in avoiding whipsaws like the one in today's at 1.30 PM. As market has consolidated for two days near 2860 & today it made a higher base at 2880, after a rise till 1.30PM, it corrected in a flag like fashion and then again broke out & went up.If you believed in the strength of the market at that time holding 2860-2880 & trying to climb 5 day ema(2946), you will look at that fall as a consolidation flag and wait out.

Even if you lose in those whipsaws, you still end up in profits.

Regarding the buy & sell signals:

I keep watching the red dots as they come down & forsee the next dot by their gaps and see the corresponding levels and close the shorts if the level is breached & initiate a long trade knowing well the green dot will appear once that certain level is breached. And vice versa for green dots.

For eg. At 11.45 AM the red dot was at 2910. I initiate a buy the moment 2910 is cleared, not waiting for the green dot to appear because the basis of SAR is "Stop And Reverse". So the green dot will come if Nifty crosses the previous red dot & vice versa.If you wait for a green dot, that particular candle can be so big, you will miss buying low.

You can minimise your trades by initiating only those which give a buy when stochastics is reversing from below 20 & rsi from below 20 - 30 mark.And a sell when stochastics is reversing down from above 80 & Rsi from above 70-80.

And for todays trading the key levels were 2860(Previous days low) & the 5 day ema (2946) and markets behaviour around these levels helped in making trade judgements.

I hope it clarifies some of your doubts. Go in with your own preparations based on informations collected from so many blogs, forums but filter it down to simple basic data & tradeable plans.
