Field notes on time series forecasting in automated trading: mechanics, configuration, and the pitfalls that surface in production.
How It Works
time series forecasting operates as a pipeline: ingest, compute, decide, route. Each stage has its own ways to break.
Configuration
Configuring time series forecasting comes down to a handful of parameters. Vendor defaults suit demos; production deserves its own tuning pass.
Failure Modes
The failure record for time series forecasting includes regime changes, missed heartbeats, and positions that could not be closed gracefully.
Evaluation
Assess time series forecasting with fixed look-ahead-free tests, then stress the operational side before calling it production-ready.

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 |
