Quote Type refers to List of the possible conventions that the traded price of a CDS is quoted.
Available Quote Type types:
Spread
According to this convention, the fair premium is used to quote the value of a traded CDS
This is in turn defined as the annualized percentage of notional that the protection buyer would have to pay on the predefined dates over the life of the swap in order for the present value of the swap to be exactly zero.
For example, a quote of 0.04 means a 400 basis points premium, whereby an amount equal to 4% of the notional would have to be paid each year (until default or maturity) in order to make the swap having a zero present value.
Up Front
According to this convention, the so called points upfront is used to quote the value of a traded CDS
This is in turn defined as the percentage of notional that the protection buyer must pay once at inception in addition to also paying a fixed coupon rate (referred as running spread) on the predefined dates over the life of the swap.
For example, a quote of 0.1 means that an amount equal to 10% of the notional minus the accrual over the unprotected initial period would have to be paid at inception in order to make the overall cds contract having a zero present value.
