The setback of using this "Opening Strategy" is that if the market opens not within one of the suggested forecasts, then a day of trading would be wasted. If this happens for several days, it would mean more days would be wasted. So it is suggested that a person should have multiple of strategies so that if one strategy does not work, he still has other methodologies to follow.
As for today and a few days next week, I am going for a short days off for my Hari Raya, so I would rather feel not to do any forecast for today. Further more I could see that lately the volatility of the market has not been very encouraging.
Have a nice trading day guys.....
Selamat Hari Raya
