Ankit, RKK you are right in your belief and thats what we trade in the market.
My belief is slightly different, When I look at the chart, I try to read the price action. If I remove the date and time data from X-axis of chart, then at mkt open, I will have a Long Bar and nothing more then that. So at a chart, with blank time axis, my interpretation to long bar will always remain the same irrespective of the time of the day.
If the price levels of that action are accepted by market i.e.
- mkt trades above that then it is same as any other breakout,
- retraces partially and then moves in the same direction then it is same as any other breakout + retracement + continuation case
- or mkt rejects this price and reverses then it is same as false breakout
My usual reaction to such unsual price action is to use extra filters like wait for 2 bars, or wait for first 30 mins on my strategies before taking action. Even if it comes at 2.30 pm or 10.00 am.
This approach has given me more consistency in interpretation of chart.
In future (I am dreaming now..), when NIFTY goes for 24hrs trading, we will see more such events. This is very common in other mkt that are traded 24*7 like forex, S&P 500 or Dow futures.
If we draw the indicators over 5 days price action, then they generally show spike due to this unusual movement. As a system developer, we need to devise some method to handle this abnormal calculation. One of the shortcoming of MA category indicators is that it is sensitive to such unsual bar size and becomes unstable for next few bars. When such long bar becomes part of calculation period, or drops from calculation period, MAs show a spike. Shorter the calcuation timeframe, more prominent is the impact.
Hope this gives you different perspective to the reader. As I always say, backtest the sytem before trading so don't jump and start putting money on new perspective.
All the best with your approach and Happy Trading.
