Rob's Session Highs and Lows

This indicator plots key intraday structure levels for index and futures traders who track the Asia, London, and New York sessions, plus overnight H1 and H4 levels, without breaking the chart autoscale.

It automatically tracks and draws:

Asia session high and low

London session high and low

Previous New York session high and low (PDH and PDL)

Overnight session H1 and H4 highs and lows

All sessions are interpreted in New York time, and the Asia, London, New York, and Overnight windows are fully configurable so you can match your own session definitions.

Features:

Separate color, style, and width controls for Asia, London, Previous Day, H1, and H4 levels

Optional labels on the chart, with the choice to pin them to the right edge or offset them into the past

Clean vertical session dividers that stay within the current daily range so they do not crush the autoscale

Price scale markers (AH, AL, LH, LL, PDH, PDL, H1H, H1L, H4H, H4L) for quick reference even when levels are off screen

Optional alert conditions for when price crosses any session high or low, as well as Overnight H1 and H4 levels

Use it on your intraday charts to quickly see which session ranges have been taken out, where the prior New York range sits, and which overnight H1 or H4 levels are in play.
