Trading Model Post-Training Workflow FAQs

Question 1

What is walk-forward validation in this workflow?

Accepted Answer

It is a method of testing a model's out-of-sample performance across multiple sequential time periods to ensure performance is consistent and not a result of overfitting.

Question 2

How do I know if a model is ready for live deployment?

Accepted Answer

A model is considered ready for live deployment if it passes gating thresholds and achieves at least 4 out of 5 positive folds with low variance during walk-forward validation.

Question 3

What is the difference between proxy and real Max Drawdown?

Accepted Answer

Training MaxDD often measures reward volatility (proxy), which can be inflated. This workflow uses backtesting to find the real equity drawdown, which is typically much lower.

Question 4

Why does this skill require the Alpaca API?

Accepted Answer

Alpaca is used to provide accurate market data for both stocks and crypto (like UNIUSD), ensuring that backtests reflect real trading conditions better than generic providers.

Question 5

How long does the validation process usually take?

Accepted Answer

A standard 5-fold walk-forward validation for one model takes approximately 35 to 40 minutes, with each fold processing around 250 bars of data.
