Lineshotkey RTwo clicks — it extends to the right edge on its own

A trend line that keeps going — through your second click and on to the right edge of the chart. For reading a trend forward instead of admiring it backward.

The same two-point line as the Line tool, extended automatically through the second anchor to the right edge of the chart, projection gutter included. Where a Line documents the past, a Ray asks the forward question: if this trend holds, where is price allowed to be next week?

Arm it (R), click two points on the trend. The segment you defined draws solid and the extension carries it to the right edge. Everything else — selection, removal, persistence — works like any other drawing.

Universal mechanics: every tool is single-shot (it disarms after each drawing — the pin beside ✏ Draw re-arms it in one click), Esc cancels mid-drawing, clicking a finished drawing selects it for the ✕ Remove chip, and drawings persist per symbol, anchored to their candles.

The extended portion is a hypothesis, not data. Its value is the intersection: where the ray crosses next Friday, next month, the expiry you are looking at — that is the price the trend "predicts" for that date, and watching price against it tells you daily whether the trend is keeping its promise.

Sellers use rays to project a support trend forward to an expiry date: where will the trend line be when this contract expires? A strike below that projected point is behind the trend at the date that matters, not just behind it today. The Expected Move cone asks the options market the same question — drawing both shows where the trend's answer and the market's answer disagree.

Like everything in this guide, these are descriptions of conditions and reference levels — context for your own decisions, not instructions to trade.
