Horizontal ray

A horizontal ray starts at a chosen point and extends to the right at a constant price. It marks a level from the moment it was created, so the chart shows both the level and where it comes from, without crossing older prices.

What it's for
  • Mark a level from the swing or the gap that created it.
  • Keep track of levels that price has not revisited yet, without crossing older price action.

Why start a level at its origin

A level exists because of an event: a swing high where sellers took control, a low where buyers stepped in, the close before a gap. Starting the line at that event documents why the level matters and makes it obvious whether price has been back to it since. A level that has not been revisited is often called untested; the first return to it is usually the most significant one.

Horizontal ray starting at a swing high, untouched for weeks, then retested once before a pullback
The ray starts at the swing high that created the level. Price does not come back to it for weeks; the first return reaches it almost exactly and sellers react, sending the price lower.

How to draw it

  1. Choose Lines → Horizontal ray.
  2. Click the candle where the level originates. With the magnet on, the ray snaps to that candle's high, low, open or close.
  3. The ray extends to the right edge with its price shown on the axis side.

Limits

  • As with any level, the first test is the most reliable; repeated tests consume the orders resting there.
  • Use a full horizontal line when the level also mattered before its origin (an old range boundary revisited).

Charts in this guide use simulated prices generated for illustration; levels and outcomes shown are examples, not observations of a real market. Educational content only, not investment advice.
