How do you use walk-forward optimization?
- Step 1: Get all relevant data.
- Step 2: Break data into multiple pieces.
- Step 3: Run an optimisation to find the best parameters on the first piece of data.
- Step 4: Apply those parameters on the second piece of data.
- Step 5: Run an optimisation to find the best parameters on the next in-sample data.
