A continuous chart joins a series of futures months to show price history. It is not a full order destination. The app still needs a contract that can trade. Read that contract’s month before a test, and check how the app handles a chart rollover.

Step by step
- 1 Identify whether the signal chart uses a continuous series.
- 2 Choose the intended executable expiry in TWS and check Description.
- 3 Review the app’s current symbol and rollover mapping.
- 4 Compare the resolved contract with the intended product, month, and multiplier.
- 5 Keep a separate record of existing positions when changing the mapping.
A practical example
Think of a continuous chart as a way to view a long price history. It is not proof that your order has a specific contract month. The broker still needs a tradable product. Read the app’s resolved contract before a test. If the chart switches from one month to the next, check what happens to new entries and what happens to exits for an old position. Do not treat the chart switch as a trade. A picture can change without any broker order being sent, filled, or closed.

Common questions
Does changing the chart roll my broker position?
No. A chart change is not a broker execution.
Can every app accept a continuous symbol?
Use the specific mapping supported by the app.
