Was reading a 2011 forum post about crude oil futures slippage and someone wrote that the slippage was as high as 30 - 50 ticks intraday earlier that year. I would guess it was much worse during 2008. can I rely on nadex spreads consistently giving me a 1 - 3 tick spread with no slippage even when CL is moving fast and there are large spreads on cl futures?
