Show Extended Hours (Futures & Crypto)

OVERVIEW
This indicator mimics TradingViews "Extended trading hours" background color settings. It is most useful on symbols that do not conventionally have extended hours, but are available to trade during those hours (ie. Futures and Crypto). Because market participation (ie. volatility) in a given symbol can change dramatically at or near these transitions, seeing conventional market open / closures expedites price action context around these transitions.
