I have a current trade in SPX. I noticed today that, when OV modeling is set to Variable, the current price is well below the T+0 line. When I use EIOIO as the modeling framework, the Graham dot is spot on the T+0 line. I have experienced this any number of times in other trades as well. Does this mean that the EIOIO is actually doing a better job of modeling how the market is pricing my overall position in this trade? I have attached two screenshots to show the difference.
