Trying to catch the spikes countertrend is the name of the game, but most likely you won't be filled at the top. You would lose a tick or so, which is pretty much all the profit potential when it comes to condors...Still possible with member fees though IMO...
I don't remember if the actual condor native spread is active on CL. You need to check native quotes to know the profit potential.
We trade CL Condors all the time - but we are holding them for weeks typically not minutes.
Daytrading Flys and Condors makes little to no sense. But it's a great swing trade. The margin on a CL Condor would be just a fraction of the flat price initial margin - no reason at all to get flat at the end of the day unless your goal is to enrich the CME and your broker.
For flys, do you do them via equal-weighted wings? O your do something more sophisticated to make them neutral to the first and second order moves?Natty, Eurodollars, and Sugar Flys have been doing really really well for the boys. Guys are having a lights out 2017 to date.
