Not until I resolve the last issue that has been chronicled here. It _could_ be used now since the parameter inverted back correctly, and the tracking "error" is totally within historical norms, but hacking always leaves a bad taste in my mouth. I can hack, but I would rather get it right.
FWIW: SPX 1298.36. 1306.52. There was an error in todays FV numbers. Subtract about 9 and that is the proper value. I am in the process of automating this new feature so that I don't have to do this particular chore by hand, and it caused an error.
So the long would have been 98 or so ES. Although the position fluctuated between -5 and +6, we are now again at -5, so I say this call also failed.... Maybe you should introduce a -1 multiplier to make it work...
