Hi ,
The curve is always using the real spread (upfront+running), so, any bootstrapping should not deal with the upfront trades/quotes.
Remember a financial institution may have a mixture of trades (upfront and not upfront ) for a single name(i.e. the non upfront trades booked year ago and the upfront trades the last few months), they have to MTM all those trades using the same curve.

Just a quick note on this (if anyone is thinking of implementing something) - it is also quite common for a contract to be both... i.e. have an upfront payment plus a running spread. So, incorporating a simple payment at the front of a CDS could be the simplest way of allowing upfront prices.Simon

it would be nice to have the possibility to use directly that upfront
when bootstrapping credit curves and when pricing CDS contracts.
I was wondering if anyone has thought about adding this feature or is
willing to share any ideas.
Thanks,
