I'm in the one-week P605 & P600 CMG calendar. Long July 31, short July 24. CMG reports on July 21.
Entered at different prices between $0.92 - $1.09. Averaging at about $1.00 which I believe is a good entry price.
Spreads are wide - be careful!
A few cycles back I entered at $1.25, exited at $1.30, and watched the price going all the way up to $1.75...
