[KA] Rate of Change

Rate of Change (ROC)

Given a source series, calculates a running Rate of Change -- simply the percentage difference between the current value of said source to the value N bars back.

One nicety here, compared to the stock tradingview indicator is allowance to force plot certain bounds. This allows more visibility on the relative movement of the series within the plotted bounds.

For example, you know the particular bounds for a timeframe, and can visibly see when those bounds are violated.
