Building the chart
Price scale, grid and snapping
The price step everything snaps to, when to lock the range by hand, and how to override snapping mid-drag.
The price scale decides two things: what prices the chart covers, and what increment everything snaps to.
The price step
Leave it at 0 and a sensible step is chosen from the range of your candles. Set a number
and every candle handle and every level snaps to that increment.
Setting it explicitly is worth doing whenever the chart represents a real instrument, so your levels land on round numbers instead of near them.
Hold Ctrl while dragging for a 10× finer step on a candle, or for free placement when drawing a zone or a line.
Zone edges snap between candles
A zone's edges snap to the gaps between columns rather than to a column's centre, so a zone reads as covering whole bars instead of slicing two in half. Turn that off in the same section to place edges anywhere.
The visible price range
By default the range grows to fit whatever is on the chart — it expands outward and never shrinks. That is also what backs the camera's guarantee that a zoom shot always contains what it points at.
Locked price range pins it to numbers you choose instead. Use it when:
- The automatic range keeps shifting as you edit and you want the composition to stay put.
- You are building something where the framing itself must not reveal anything — this is how the quiz generator keeps the answer out of the picture.
Grid and price labels
These are two switches, not one.
- Grid draws the lines.
Bleedruns them to the edge of the canvas and drops the min/max emphasis, for a cleaner background. Candle spacing and margins are unaffected either way. - Price scale draws the numbers. Grid off with prices on is a valid and common combination.
These two DO reach the export
Most of what is under Appearance is your working view only. Grid and price labels are not: they are part of the composition. The things that stay in the editor — crosshair, snap markers, candle numbers, safe-area outlines — are covered under themes and styles.
Candle numbers
Settings → Appearance → Theme → Candle numbers prints the column index above every fifth candle, thinned further when labels would collide.
It is a counting aid, not a time axis — which is why it lives on the canvas and not in the timeline dock, and why it is editor-only. When you need to know when something happens rather than which column it sits on, read the timeline, which speaks seconds and nothing else.
