It normally turns out to be months... In reality, it's either until it works, gets too close (i.e. a fly that has the front contract as one of the wings isn't really a fly) or something fundamentally changes that makes me reassess the whole thing. That's why one of the most important metrics for me when evaluating these trades is rolldown.Quote from Trader13:
Martin, your ten-year chart inspires a question: What is your average hold time for an ED fly?
