TradePose Models
Shared Pydantic contracts, enums, indicator calculations, and Polars schemas for TradePose packages.
Installation
pip install tradepose-models
Python 3.13 or newer is required.
Indicator specification
Indicator is the public calculation factory. IndicatorSpec adds canonical source
provenance and resolved wire identity.
from tradepose_models.enums import Freq
from tradepose_models.indicators import Indicator
from tradepose_models.strategy import IndicatorSpec, SourceDescriptor
source = SourceDescriptor(instrument="NAS100", freq=Freq.DAY_1)
atr_spec = IndicatorSpec(
source=source,
shift=1,
indicator=Indicator.atr(period=14, shift=1).config,
)
assert atr_spec.instrument == "NAS100"
assert atr_spec.indicator_id.startswith("sha256:")
assert atr_spec.column_id.startswith("ind_v1_")
assert atr_spec.public_name.startswith("NAS100@1D:ATR(period=14)")
assert atr_spec.output_ref().indicator_id == atr_spec.indicator_id
public_name is presentation metadata for logs and friendly artifact views.
column_id is the only physical DataFrame column name; col() selects that struct
column and callers then select a declared field such as .struct.field("value").
short_name and display_name() are not part of the indicator API.
Typed authoring dependencies
Authoring dependencies use IndicatorRef; resolved IndicatorOutputRef values belong
only to compiled IndicatorSpec wire data. Do not substitute readable labels or
physical ind_v1_* column identities for typed references.
from tradepose_models.indicators import Indicator
from tradepose_models.strategy import IndicatorRef
atr = Indicator.atr(period=14, shift=1)
atr_quantile = Indicator.atr_quantile(
IndicatorRef(name="atr"),
window=252,
quantile=0.5,
shift=0,
)
supertrend = Indicator.supertrend(
3.0,
IndicatorRef(name="atr"),
shift=1,
)
For open-driven decisions, indicators reading high, low, close, or volume
require shift >= 1. A literal current-bar column="open" may use shift=0.
Core modules
tradepose_models.strategy: strategy, graph, authoring, manifest, and portfolio data contracts.tradepose_models.indicators: calculation models and theIndicatorfactory.tradepose_models.enums: shared frequencies and trading enums.tradepose_models.schemas: trades and timezone-aware OHLCV schemas.tradepose_models.export: typed export request and response contracts.
Experiment catalogs, workspace lifecycle, execution, and portfolio promotion are
owned by tradepose-client; Models does not provide a Python strategy registry.
