A box will start to draw an hour after the market open and continue being drawn for the next two hours. This is being done due to the theory of it being the time where small investors and institutions are moving the price with less than the first hour.
Once the Box has been closed of the day will be drawn. Price should try remaining between t his two.
There are alerts for the breakthrough of the box to either upside or downside. This should be followed by a corresponding direction candle pattern, in order to expect a higher/lower break.
