Creating Smart Curves with Fusion AI

Fusion AI can create Smart Curves directly on the platform on your behalf — no ODSL scripting required. You describe the curve you need in plain language, Fusion AI confirms the details, and then creates it for you using its built-in Smart Curve tool.

The Full Curve Creation Workflow​

Describe your curve → Fusion AI confirms details → Creates the curve directly → Ready to use

You stay in control at every stage — Fusion AI explains what it will create and waits for your approval before making any changes.

Step 1: Describe Your Curve​

Start by telling Fusion AI what curve you need. Be as specific or as high-level as you like — it will ask clarifying questions if it needs more detail.

You: I need a daily power forward curve for the UK, blending EEX and broker data. EEX should take priority. Rebuild it automatically whenever the EEX settlement data arrives.

Fusion AI: I'll create a Smart Curve with the following configuration:

  • Base: EEX UK power monthly settlement (EEX.UK_POWER_M:SETTLE)
  • Blend: EEX priority over broker (ICAP_BROKER.UK_POWER_M:MID)
  • Build: Bootstrap then interpolate to daily using cubic spline
  • Caching: OnDependencies — rebuilds automatically when EEX data updates

Shall I go ahead and create it?

Step 2: Confirm and Create​

Once you confirm, Fusion AI creates the Smart Curve directly on the platform — no script to run, no code to copy.

You: Yes, go ahead.

Fusion AI: ✅ Done. The Smart Curve UK_POWER_OBJECT:CURVE has been created and is active in your environment. It will rebuild automatically whenever EEX.UK_POWER_M:SETTLE updates.

tip

You can ask Fusion AI to explain any part of its proposed configuration before you confirm. For example: "Why cubic spline rather than linear interpolation?" or "What happens if the broker data is missing?"

Step 3: Refine Through Conversation​

You can ask Fusion AI to update an existing curve at any time, just by describing the change:

You: Can you change the caching to rebuild on a schedule instead — every weekday at 18:00?

Fusion AI: Updated UK_POWER_OBJECT:CURVE — caching is now set to OnSchedule with a cron of 0 18 * * MON-FRI.

You: Also change the broker source to MAREX.UK_POWER_M:MID.

Fusion AI: Done — the VAR1 input has been updated to MAREX.UK_POWER_M:MID.

note

Each change is applied directly to the platform. You can ask Fusion AI to describe the current configuration of any curve at any time to confirm the state.

Asking Fusion AI About Existing Curves​

Fusion AI can interrogate and explain curves already in your environment:

You: Why hasn't the NBP gas curve rebuilt today?

Fusion AI: The curve is configured with OnDependencies caching. Checking the dependency status — ICE.NBP_M:SETTLE has updated today but ICE.NBP_Q:SETTLE has not yet arrived. The curve will rebuild automatically once the quarterly settlement data lands.

You: Can you change it so it only depends on the monthly settlement?

Fusion AI: Updated — ICE.NBP_Q:SETTLE has been removed as a named variable input. The curve will now rebuild on ICE.NBP_M:SETTLE updates only. Note that the build expression will need to be adjusted too — shall I update it to bootstrap from the monthly series only?

Common Fusion AI Curve Requests​

RequestWhat Fusion AI does
"Build a spark spread curve for CCGT plants in Germany"Creates a spread curve with power minus gas multiplied by heat rate
"Create a Brent crude forward curve from ICE futures"Creates a bootstrapped monthly curve from ICE Brent contract settlements
"Apply a seasonal shape to our base gas curve"Creates a shaped curve using your existing seasonal profile data
"Blend our internal model prices with exchange data for the far curve"Creates a priority blend switching from exchange to model at a specified tenor
"Change the NBP curve to rebuild every hour during the trading day"Updates caching to OnSchedule with the appropriate cron expression

Tips for Getting the Best Results​

tip

Name your data sources. Fusion AI works best when you specify the exact feed you want — exchange name, broker name, or master data ID. If you're unsure of the exact ID, describe it and Fusion AI will search your environment.

tip

Start simple, then iterate. Define the core build logic first, then ask Fusion AI to add caching configuration, additional inputs, or expression changes in follow-up messages.

note

Fusion AI knows your environment. It has access to the data and curves already in your environment, so it can suggest the right source IDs and warn you if a referenced dataset doesn't exist.
