Chart Indicator

You create visual checks. Charts do not replace validation or audit.

Current Tool Signature

oxq.tools.chart.chart_indicator plots indicator columns from a stored RunResult in the tool session:

from oxq.tools.chart import chart_indicator
result = chart_indicator(
    run_id="run_1",
    symbol="SPY",
    columns=["sma_fast", "sma_slow"],
    overlay=True,
)
print(result)

It does not accept raw data=..., indicators=..., or output=... arguments. If you need a chart from raw bars, either run the strategy through the tool/session flow first or write a one-off exploratory script and label it as non-standard.

Dependency

Install chart dependencies before rendering:

uv sync --extra chart

If using pip:

python -m pip install -e ".[chart]"

What To Check

• requested columns exist in the run's symbol data
• NaN warmup regions are expected
• indicator scale matches overlay choice
• signal events line up with intended dates
• chart output path exists

Red Lines

• Do not use charts as proof of profitability.
• Do not hide missing indicator columns by plotting a different column.
• Do not infer causality from visual overlap alone.
