NY Exchanges Trading Hours Shading

This indicator shades 24-hour charts (e.g. crypto), similar to how TradingView can shade NYSE and NASDAQ traded securities for after-hours and pre-market trading hours.

But unlike standard securities charts, it doesn't also hide fully-closed hours - it shades them a third color.

Why?

- Even when trading crypto or non-Yew York market securities, you need to be aware of when the New York markets open and close. The whole world, including crypto price action, is often strongly affected by the New York stock markets. (Especially just after opening, and just before closing.)

- "After-hours" trading hours (4:OOPM to 8:00PM) are shaded with a subtle blue background, by default.

- "Pre-market" trading hours (4:00AM to 9:30 AM) are shaded a subtle orange background, by default.

- Completely closed hours in between - and weekends - are shaded a subtle dark green, by default.

This has no awareness of trading holidays - only weekends.

By default it disables itself on day view and higher.

Regular trading hours are from 9:30AM to 4:00PM Eastern time, Monday through Friday. Those may be different times in your time zone, which this takes into account, including daylight savings time. (Obviously if you aren't in US Eastern time, you don't want it shaded based on 9:30 to 4:00 your local time - you want it based on whatever New York time is for you.)
