Chart Drawings

Reference for chart drawings in Tradeways — available drawing tools, how they are persisted, and how they appear on trade charts.

What Are Chart Drawings?

Chart drawings are technical analysis overlays that you place on a trade's price chart. They are saved per trade and sync in real time, so drawings persist across sessions and devices.

Available Drawing Tools

Tool	Description
Horizontal Line	An infinite horizontal line at a specific price level.
Segment	A straight line between two points (time + price).
Horizontal Ray	A horizontal line that extends from a point to the right edge of the chart.
Price Line	A labeled horizontal line showing the exact price value.
Rectangle	A rectangular zone defined by two corner points (time + price).

A Cursor tool is always available to switch back from drawing mode to normal chart interaction.

Delete All

A dedicated "Delete All" button removes every user-created drawing from the current trade chart in a single action.

Persistence

Each drawing is stored as a separate record linked to a specific trade. The stored data includes:

Field	Description
Overlay name	The drawing tool type (e.g. Horizontal Line, Segment, Rectangle)
Points	Array of anchor points, each with an optional timestamp and price value
Styles	Optional JSON string containing custom visual styling
Extended data	Optional JSON string for tool-specific metadata
Locked	Whether the drawing is locked against accidental moves

Limits

Each trade supports a maximum of 50 drawings. Attempting to add more will result in an error.

Sync Behavior

Creating a drawing — saved to the backend immediately when the drawing gesture completes.
Moving a drawing — changes save automatically after you finish moving the drawing.
Deleting a drawing — removed from the backend immediately.
Cross-device sync — drawings load automatically when the trade chart opens. Changes made on one device appear on others in real time.

How Drawings Differ from Trade Markers

Drawings are user-created overlays for analysis. They are distinct from the system-generated trade markers (entry/exit arrows, stop-loss/take-profit lines, risk/reward zones) that Tradeways places automatically based on execution data and trade levels.
