prediction value.... take your last swing down draw a rectangle connecting the high and low of upper or lower wall .... then draw a trend line diagonally across the rectangle going up this time ... use that to draw a channel of the same approximate width the of one which went down before .... use this for prediction value.... ... until you have the actual points
In reference to the chart you posted prior to this post, would the upper wall be the 1101 point and the lower wall be the 1029 point?
