Trading Range Open so mostly a limit order market and Breakout Mode. The bulls will look for a double bottom or wedge bottom and then a swing up. The bears want a double top or wedge top and then a swing down.

When the day opens with a clear trading range presented by multiple legs, there is a very good chance that any trend attempt away from it will at least attempt to turn back into the range due to the magnetic effect of the consolidation, this is similar to the case that market tends to test the apex of the triangle at certain time after the BO, if there is a BO. Often, the trend will reverse exactly at the measured move of the opening range as shown on 20230206.

If the reversal is successful, market will attempt to take out the other extreme of the day. On this example https://ninetrans.blogspot.com/2012/01/measured-move-of-opening-range.html, a successful reversal attempt to take out the other extreme of the day (b29) and can result in a trend in the new direction. When the breakout attempt is during lunch hour, the pullback could be complex and drawn out (b29-46). The fewer the bars the pullback has, the higher the chances of a successful reversal.

When the opening range is relative small, traders will expect a MM up or down breakout of the OR at certain time, for e.g. 20230523.
