It is a good idea to confirm this information and update to the after hours trading. In the morning watch CNBC to see if there is high activity on any stocks as that will kick the price. This is purely a matter of subjective judgment based on experience that we have not yet quantified. The overall price change is hard to guage because of the very short time, but we like to see a one percent change in either direction.
Huge moves are warnings as they often change direction very quickly.
This is a prime indicator of direction change. No, but it gives you an indication of the potential. We may apply a correction factor if the average trading volume is significantly different or the stock is reacting to good or bad headline news. If you saw these issues moving up, or down, with these parameters we felt it would clearly indicate a trend and should be traded. If they do not hit all the marks we stay out.
