Plotting

Plotting indicators

Indicators and associated signals can be easily plotted using the plot_indicator(ctx, name, x, y, signals) keyword.

Where:

• name: name of the indicator on the chart
• x: values to use for the x axis
• y: values to use for the y axis
• signal: (optional) x values for which a signal is fired

Example where the goal is to plot the value of the rsi indicator from the example script.

await op.plot_indicator(ctx, "RSI", time_values, indicator_values, signal_times)

Plotting anything

Anything can be plotted using the plot(ctx, name, ...) keyword. The plot arguments are converted into plotly charts parameters.

Where:

• name: name of the indicator on the chart

Optional arguments:

• x: values to use for the x axis
• y: values to use for the y axis
• z: values to use for the z axis
• text: point labels
• mode: plotly mode ("lines", "markers", "lines+markers", "lines+markers+text", "none")
• chart: "main-chart" or "sub-chart" (default is "sub-chart")
• own_yaxis: when True, uses an independent y axis for this plot (default is False)
• color: color the of plot
• open: open values for a candlestick chart
• high: high values for a candlestick chart
• low: low values for a candlestick chart
• close: close values for a candlestick chart
• volume: volume values for a candlestick chart
• low: low values for a candlestick chart

Example:

await op.plot(ctx, "RSI", x=time_values, y=indicator_values, mode="markers")
