Just seeing if anyone is currently actively trading these at prop firms. If so what ratios are you using as a rule of thumb? I have charted up 4-3+1 for both flys. (see attached) I would be very interested if anyone is clearing Advantage or similar and what round trip costs are possible compared to prop. The brokerage would need to be less than 1 tick in the fly to make it viable imo. I am aware you can get the fly on via uk prop firms for around 0.6 ticks which is workable however I am more interested in the treasuries. Thanks
