Quote from rallymode:
I see what you are saying but to me it doesnt matter whether you view the vertical as a part of FLY's or any other combo. I am talking from a r/r perspective on that SPECIFIC spread. What i am saying is that you are less likely to get a fill on the 10 pointer vs the 5-pointer unless you give up some credit i.e. reduce your r/r. If you can manage to get a fill on a wider spread for the same r/r, you are in a better trade.
Example:
1340/1345 BCS for $1 credit r/r 1:4
1340/1350 BCS for $2 credit r/r 1:4
Now whether the first spread is really worth the quoted $1 when the 10 pointer is $2, i doubt it. But since things are only worth what you can buy/sell them for, the instant you place your trade if you can manage to get the 10 pointer for $2 when you can only get the 5-pointer for $1, you are in a better position. That's all i was saying.
