Quote from bone:
You have to be very careful and really do your scouting in terms of trading flys and condors on a HF basis - the slippage will eat you alive. Look at the actual order books for the individual legs in lieu of the charts (there is a latency artifact in the charts for the last print versus the actual bid and offer in the lower volume legs - makes the trading range appear larger than it really is).
Totally agree - not sure how you do that on an automated basis - but as Foo, I think, said earlier, you do need to be in front of the screen watching the market a lot knowing where you can get filled etc. quite a bit of fly trading in oil boils down to getting into the individual spreads at good levels
