This indicator was built to visually demonstrate the significance of major, untouched pivots. With traders commonly placing orders at or near significant pivots, these areas are commonly referred to as Resting Liquidity. If we attribute some factor of growth over time, we can quickly visualize that certain pivots originated much further away than others, if their channels appear larger.
A pivot in this case is validated by the Liquidity Strength parameter. If set to 50 for example, then a pivot high is validated if its high is greater than the high of the 50 bars to the left and right of itself. This also implies a delay in finding pivots, as the drawings won't actually appear until validation, which would occur 50 bars after the original high has formed in this case. This is typical of indicators using swing highs and lows, as one must wait some period of time to validate the pivots in question.
The Channel Growth parameter dictates how much the Liquidity Channels will expand over time. The following chart is an example, where the left-hand side is using a Channel Growth of 1, and the right-hand side is using a Channel Growth of 10.
When price reaches these levels, they become invalidated and will stop extending to the right. The other condition for invalidation is the Delete After (Bars) parameter which, when enabled, declares that untouched levels will be deleted if the distance from their origin exceeds this many bars.
This indicator also offers an option to Hide Expanding Channels for those who just want the actual levels on their chart, without the extra visuals, which would look something like the below chart.
