✔ Four anchors in one indicator — Asia, London, New York and Daily — shown together or one at a time.
✔ On-chart control panel with one button per anchor plus a Band button, so any line can be switched on or off without opening the settings.
✔ The panel can be dragged anywhere, minimized to a small bar, and keeps its position and button states when you switch timeframe.
✔ Standard deviation bands, up to three levels per side, with an adjustable multiplier for each level.
✔ Session hours are set in UTC and the broker time offset is detected automatically, with a manual override for unusual servers.
✔ Sessions that run across midnight are handled, so the Asian session can be defined however your plan requires.
✔ The VWAP is computed on a lower timeframe of your choice, one minute by default, and mapped onto the chart bars.
✔ The line for the session in progress updates on every tick, not only when a new bar opens.
✔ Past sessions can be shown for a chosen number of days back, for reviewing how price behaved around earlier session VWAPs.
For every bar of the calculation timeframe the indicator takes the typical price — high plus low plus close divided by three — and weights it by the volume of that bar. Inside a session it keeps a running sum of price times volume and a running sum of volume; the VWAP at any point is the first divided by the second, so the line is the average price actually traded since the anchor rather than a simple moving average. The bands come from the volume weighted variance of the same prices, so they open wide right after the anchor, when only a few bars have been counted, and tighten as the session fills out. Each anchor keeps its own running sums and resets when its session starts again.
