To add a formula using spot price series, in formula view:

1. Click on to create a new line.
2. In Formula Name, enter the formula name. For example : Platts Singapore HSFO Visco spread (180-380)
3. In Formula Description, enter applicable description for the formula.
4. In Formula Unit, select the unit to be used for this formula.
5. In Formula Ccy, select the currency to be used for this formula.
6. In Premium Amount, enter a premium amount for the formula if a premium or discount is to be applied to all the Formula Item in the formula. For discount, negative sign is to be used before the amount. For example : -2.00.
7. In Premium Unit, select the unit to be used for the premium amount in this formula.

8. In Item Ccy, select the currency to be used for this item in the formula.
9. In Premium Amount, enter a premium amount for the item in the formula if a premium or discount is to be applied to this item in the formula. For discount, negative sign is to be used before the amount. For example : -2.00.
10. In Premium Unit, select the unit to be used for the premium amount used in this formula item.
11. In Premium Ccy, select the currency to be used for the premium amount used in this formula item..
12. In Apply Calc, if the premium/discount is to be multiply by a price series in the formula item, *Price is to be used.
13. In Apply Calc Price Series, it is associated with "Apply Cal". Select the price series to be used in the multiplication.
14. In Apply Calc Period,, select a period is to be used for price series used in the "Apply Cal Price Series". This is typically used for forward price series.
15. Click to confirm creation.
16. To edit formula item details after creation, Click to edit.

For example, for a Visco Spread, the formula item will be as per below.
