feat: Add YesterWap indicator

[JGronholz]

This is a screenshot of my TradingView indicator YesterWAP, a posh daily-anchored VWAP that remembers what happened yesterday.
VWAP, mean-reversion, and volatility bands are all tried-and-true, so this integration of them should be the same.
Daily-anchored VWAP requires an intraday timeframe.

Asian Monday morning sets the mood for the whole week.
NY Monday morning has different ideas... FOMC meetings... Mid-week reversals...
If yesterday's support/resistance is going to hold, it will prove it at/near the YesterWAP.
Will this trend continue? We don't know until we test the YesterWAP.

1. The white centerline is the daily-anchored VWAP.
2. The other white lines are volatility bands centered on the VWAP.
3. The YesterWAP is gray.

At daily open, YesterWAP resets to VWAP (bands too).
Then, VWAP resets to LastPrice. (typical VWAP)
Where the white ends, the gray begins.

The yellow lines show retests of the YesterWAP. Open today, close tomorrow.
The yellow circles show where we closed near/beyond the top of the YesterWAP bands.

Testing the YesterWAP resets the market for today.
Watch the reaction here. 👀
A bounce from high in the bands means pump incoming.
Rejection from low in the bands means sale incoming.
