Price Legs: Average Heights; 'Smart ATR'

Price Legs: Average Heights; 'Smart ATR'. Consol Range Gauge
~~ Indicator to show small and large price legs (based on short and long input pivot lengths), and calculating the average heights of these price legs; counting legs from user-input start time ~~

//Premise: Wanted to use this as something like a 'Smart ATR': where the average/typical range of a distinct & dynamic price leg could be calculated based on a user-input time interval (as opposed to standard ATR, which is simply the average range over a consistent repeating period, with no regard to market structure). My instinct is that this would be most useful for consolidated periods & range trading: giving the trader an idea of what the typical size of a price leg might be in the current market state (hence in the title, Consol Range gauge)

//Features & User inputs:
-Start time: confirm input when loading indicator by clicking on the chart. Then drag the vertical line to change start time easily.
-Large Legs (toggle on/off) and user-input pivot lookback/lookforward length (larger => larger legs)
-Small Legs (toggle on/off) and user-input pivot lookback/lookforward length (smaller => smaller legs)
-Display Stats table: toggle on/off: simple view- shows the averages of large (up & down), small (up & down), and combined (for each).
-Extended stats table: toggle on/off option to show the averages of the last 3 legs of each category (up/down/large/small/combined)
-Toggle on/off Time & Price chart text labels of price legs (time in mins/hours/days; price in $ or pips; auto assigned based on asset)
-Table position: user choice.

//Notes & tips:
-Using custom start time along with replay mode, you can select any arbitrary chunk of price for the purpose of backtesting.
-Play around with the pivot lookback lengths to find price legs most suitable to the current market regime (consolidating/trending; high volatility/ low volatility)
-Single bar price legs will never be counted: they must be at least 2 bars from H>>L or L>>H.

//Credits: Thanks to @crypto_juju for the idea of applying statistics to this simple price leg indicator.

Simple View: showing only the full averages (counting from Start time):

View showing ONLY the large legs, with Time & Price labels toggled ON:

Release Notes:

-Added total number of price legs in the display table (from start time; from which averages are derived). Visual legs/boxes painting on chart are limited to 500, but the actual number of legs processed by the script can be much larger than this. I wanted to clear up any possible confusion, as well as giving the user an idea of the dataset size.
-Added option to toggle on/off the visual vertical start time marker, as well as color/thickness options. Occasionally the script can glitch in realtime and this line briefly flips horizontal =>> option to turn off this visual aid if it annoys. User input start time would be unaffected.
