wick CE; plot candle wick and tail midpoint lines

-Simple little tool to plot the wick CE: an ICT concept, consequent encroachment i.e. the midpoint line of a wick or tail; it being a potentially sensitive level (depending on context).
-Wrote this to save me time drawing out fib retracement to locate the precise level of the wick CE. Example usage: show indicator, add horizontal ray over favored wick CE level, hide indicator.

~choose how many consecutive bars back to plot wick CE lines.
~choose how many bars forward to extend the wick CE lines.

Versionshinweise:

-increased max_bars_back and max_lines_count to allow for much larger lookback

Versionshinweise:

-added option to show candle body midlines too ('MT' = mean threshold)

Versionshinweise:

-added optional retracement levels (75% and 25% of high-low range); default is off.
-added minimum wick size input (based on multiples of chart symbols mintick value) to filter out small wicks; (default = 1; i.e. will only filter out wick CEs where the wick is tiny or non-existent).
-added option to show chart symbol's mintick value in top right corner of chart (default off).

Versionshinweise:

-change show current bar to default true
