Why Bubbles&Drops? The indicator involves association of simultaneous drops falling (Open < Close) and bubbles rising to the liquid surface (Open > Close). Each of these environment "disturbances" causes waves which fade after some time. Using this "consequences", we can try to forecast future price movement.

The indicator uses the simplest fading calculation - f ( x ) = a / x * sin ( x * a ), where a is an amplitude (in this case, Open - Close)

The first history bar (Open[ historyDeep ] ) is used as a start point. Values of the fading caused by each successive bar are sequentially added to the initial value.
