NSE:NIFTY   Nifty 50 Index
I normally divide my intraday trading in to three phases. It not only helps me to stay out of unnecessary risk but also to book profits at right moments.

I don't say that the stock does not go higher after I book profit but most of the time it protects my profits before the market takes it back.

The three phases I am talking about are:

Opening-Continuation Phase
Mid-Trap phase
End-Decisive phase

Opening-Continuation Phase
In this phase, I look for continuation of the previous trend. Suppose a stock has been trending higher but pulls back in the very first candle of the day. I would wait for the sellers to get exhausted before buying near the lows. In the morning, relatively smaller time frames do help to take correct entries. So this phase is to take entries.
This phase starts at 9:15 and ends at 11:00
Most of the time I do take entries by 9:30 and kill the trades at 10:00-11:00 because stocks print day highs by this time.

Mid-Trap phase
This phase is silent, where most of the traders who made some money in the morning give it back to the market. There is lot of fuming and fretting in this phase. Traders take trades out of boredom or have guilt of not taking profits. Eighty percent stops are hit in this phase. Most of the low volume trading happens in this phase.
I personally prefer to look for fake moves to fool the newbies. Once again, I don't say that I am always right.
I just look for small scalps.
This phase begins after 11:00 and ends at 1:00-2:00

End-Decisive phase
I call this decisive phase because many times the final direction of the trend is decided in this phase.
This phase is killing. Why I say so? Let's say a stock is in strong uptrend today. At the beginning of this phase you will notice a sharp dip which will wash out weak buyers. Once the weak hands are out stock zooms back to make new highs.
This one starts near 2:00 and ends at 3:30

I hope it makes sense to most who like to trade for real.
