On my chart I have been noticing a red square next to the bar. What is this for? Is this the same as the blue box that shows orders?
The little square will be red on top if the current price is higher than the bar open point (midway) and turn blue if the price drops below that point. Opposite is true for a box on the bottom of the bar, meaning that it will be red until the price moves up past the midpoint. Your example shows the price above the midpoint, so the lower one is blue and the upper one is red. If the price moves down below that middle point, that will reverse. The box represents trapped orders. Review the videos on trapped xboxes for more info.
its a leading volume indicator it will become a trapped order if it reverses
