A written reference on seasonality decomposition — how it works, how to configure it, and where it breaks under load.
How It Works
At the core of seasonality decomposition sits a chain of transformations that turns raw market data into decisions an engine can act on.
Configuration
Parameter choices in seasonality decomposition shape both signal quality and operational load. Record every change and the reason for it.
Failure Modes
The failure record for seasonality decomposition includes regime changes, missed heartbeats, and positions that could not be closed gracefully.
Evaluation
An honest evaluation of seasonality decomposition weighs quantitative metrics alongside code quality and how much attention it demands in production.
Configuration Reference

Parameter Impact
| Parameter | Effect | Trade-off |
|---|---|---|
| timeframe | Signal frequency | Higher means fewer but more reliable signals |
| risk_limit | Maximum exposure | Lower means safer but slower returns |
| lookback | Indicator sensitivity | Longer means smoother but lagging |
