Lineshotkey GTwo clicks — start and end of the span; the channel fits itself

A regression channel: click the start and end of a move and the midline fits itself through the closes, with bands two standard deviations either side. The math draws the channel your eye wanted to.

A least-squares regression over the bars between your two clicks: the midline is the straight line that best fits every close in the span, and the bands sit two standard deviations of the residuals above and below it. Unlike the freehand Channel, nothing about it is judgment — same clicks, same channel, every time.

Arm it (G), click the bar where the move starts and the bar where it ends (or today's bar for a live read). The midline and ±2σ bands draw across the span, with a fainter dashed extension carrying them to the right edge.

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 midline's slope is the span's actual trend, with the eyeballing removed. The bands answer "is price stretched?" statistically: near +2σ price is expensive relative to its own recent trend, near −2σ cheap — with roughly 95% of closes inside the bands if the move resembles a trend with noise.

The extension is the same hypothesis a Ray makes, with error bars attached.

The −2σ band in a rising regression channel is a statistical description of "stretched to the downside within an uptrend" — the condition the Pullback screener lens looks for, drawn on one name. Premium tends to be richer at exactly those moments, which is why sellers watch for them.

On a name already held, the channel of the whole position's span shows whether the stock is still in the regime it was entered in, or has left it — useful context when the weekly review asks whether a covered-call strike still makes sense.

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