Line
Lineshotkey LTwo clicks — one at each end
A straight line between two points — the most-used drawing in all of charting. Connect two lows and you have drawn what buyers have been willing to pay over time.
What it is
A trend line: a straight segment between two points you pick, usually two swing lows in a rising market or two swing highs in a falling one. It is the diagonal cousin of the horizontal level — support or resistance that moves with time.
How to draw it
Arm it (L), click the first point, click the second. Anchors snap to bars, so a line drawn off two lows lands exactly on those candles — and stays on them when you change range or interval, because drawings are anchored by timestamp, not screen position.
The tool disarms after each line. The pin beside the ✏ Draw button re-arms it in one click for the next one.
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.
How to read it
The more times price touches a trend line and turns, the more information the line carries — two touches draw it, the third starts to validate it. Steep lines break sooner than shallow ones; a broken steep line often just means the trend found a more sustainable slope.
A close through a well-tested trend line is the diagonal version of losing a level, and is often where trend-following buyers step aside.
Using it on the wheel
An uptrend line under price describes where the dip-buyers have been living. Put strikes below a rising, multi-touch trend line sit behind that behavior; the pullback-toward-the-line moment is when the screener's timing signals and richer premiums tend to coincide.
On a bag in Recovery Mode, a downtrend line over price marks what the repair has to break before optimism is a description rather than a hope.
Like everything in this guide, these are descriptions of conditions and reference levels — context for your own decisions, not instructions to trade.
