# Actualization

On the **ACTUALIZATION** screen, you can update the quantity of a trade -- but have this updated quantity only apply from a certain date forward. This is typically used for physical deliveries, where the delivered quantity differs from the contracted volume.

**To Actualize:**

1. Go to the **ACTUALIZATION** screen (which can be turned on by Molecule CS)
2. Filter to find the trades (well, legs) you're looking to actualize
3. Update the **ACTUALIZED QUANTITY**
4. (optional) Provide the **ACTUALIZED DATE**. This will default to today.
5. Hit **SAVE** for the relevant trades

From the Actualization Date forward, the Actualized Quantity will be used for valuation calculations -- as opposed to the original quantity.
