"By looking at the chart we'll have big rise very soon,

Morning zansaxon,

This quote from here may be of interest to you. Notice that "followed by a sharp price movement" is mentioned, not the direction of that movement...

"Contracting bands warn that the market is about to trend: the bands first converge into a narrow neck, followed by a sharp price movement. The first breakout is often a false move, preceding a strong trend in the opposite direction.
