Use your own Bitstamp-format data

How to point the pipeline at your own capture instead of the bundled sample, and tune the configuration for other instruments. For non-Bitstamp, non-LOBSTER sources, see Custom components.

Custom Bitstamp-format CSV

Place orders.csv and trades.csv in the same directory (a capture made with ob-analytics capture bitstamp shows the expected trades.csv schema). Point the pipeline at the orders path; it resolves sibling trades.csv automatically.

from ob_analytics import Pipeline, PipelineConfig

config = PipelineConfig(
    tick_size=0.01,
    price_decimals=2,
    lot_size=1e-8,
    volume_decimals=8,
)
result = Pipeline(config=config).run("my_run/orders.csv")

Configuration presets

Set the instrument's price step (tick_size) and size step (lot_size), with the decimals that show one step (price_decimals, volume_decimals). A lot_size finer than volume_decimals can show is refused, because sizes would be shown rounded.

config = PipelineConfig(
    tick_size=0.01,
    price_decimals=2,
    lot_size=1e-8,
    volume_decimals=8,
)

config = PipelineConfig(
    tick_size=0.01,
    price_decimals=2,
    lot_size=1e-6,
    volume_decimals=6,
)

config = PipelineConfig(
    tick_size=0.0001,
    price_decimals=4,
    lot_size=0.01,
    volume_decimals=2,
    depth_bps=5,
    depth_bins=100,
)

config = PipelineConfig(
    tick_size=0.01,
    price_decimals=2,
    lot_size=1.0,
    volume_decimals=0,
)
