This article says executions should occur at 0.29% above treasury yields. Is anyone able to consistently get executions at that rate?
A few weeks ago I was filled at about 0.51% above treasury yield, which is definitely worse than the 0.29-0.35% I previously got. Both were using IBKR smart routing and there weren’t any obvious differences, so I’m guessing box spread rates are driven by supply and demand, and there’s just relatively more supply now than in mid-2020.
After having an order entered for about 3 days, I got an execution today (Jan 22 2021) on a SPX 1000/2000 15DEC23 box for 0.65%, which is 0.46% above the 3 year treasury yield. This was using IB’s smart routing (manual routing not available).
