Though the question is for Nifty, these are applicable to any market. This is not exhaustive list but good one to start with. Do keep in mind for as many successful breakouts, there could be equal number of failed ones.
Most important. Do not get bogged down by missing breakouts and fast moving stocks. Do not feel bad and do not get frustrated. Decide on the goal - is it to make money consistently over a period of time or is it to catch each and every breakout. I know it is easy to make lot of money by catching fast moving stocks but over a period of time it gets averaged out due to
-most of these successful intra day breakouts move quickly due to HFT and algo trading, making the risk-reward ratio less favorable.
-number of failed breakouts are also high.
Here is what I would suggest
-What you are doing is completely fine, continue doing it. I know some might feel analyzing 50 stocks is too much. But when you see 50 charts every day, you training your eyes. Over a period of time it becomes easy to detect patterns, identify stocks about to breakout, differentiate between strong and weak stocks etc.
-You are planning the trades. Ensure you trade only your plans. Do not let these distractions make you divert from your plan.
-As for trading, continue if you are comfortable with these many stocks else you may try to bring it down to your comfort level.
-Develop some Volatility Breakout systems (channel breakouts for e.g.) and Trend Following Systems (like Super Trend crossover). These will help in early entry in a breakout and remain in the trade for higher profits.
-Concentrate on relatively strong stocks.
Remember volatility expansion and contractions are cyclical. Stocks that have moved may cool off while sleeping stocks may all of a sudden breakout. If you continue to do what you are doing and follow the above, sooner or later you will be able to identify breakouts, catch them early and profit considerably.
