Add strategy visuals¶
The framework collects plotting declarations and exports their data. It does not include a chart renderer. The complete plotting example adds an EMA, an RSI pane, a level, and candle colors.
Choose a phase¶
- In
init(), create panes and static lines/histograms/levels/fills using registered single-channel handles. - In
next(), place event markers and apply current-bar background/candle colors. - After
run(), callopenbacktesting.plotting.export_result(result)to obtain a plain dictionary for your renderer or JSON file.
References belong to one run. A line needs an indicator/data handle, a fill needs two compatible plot references, and a marker at position="price" needs a price. See all plotting parameters.
Color values and strings¶
Import Color or colors from openbacktesting. Color.rgb(30, 120, 220) creates a color; .with_transparency(80) makes it 80% transparent. Six/eight-digit hex strings are also accepted. Color inputs produce Color values; call .to_hex() when you need text.
self.plotting.bar_color(color) colors the current candle, and bg_color(color, pane=...) colors the current background. None clears an override. The last write for a bar/target wins, and a new bar does not inherit the previous color automatically.
