BoH if Steel can't explain it any clearer for you I doubt anyone can . It's simple why it's flawed . If it's something you can benefit from then I'm sure you would like to have it and defend . May have even helped promote them the idea like Cat did with trading years ago but who knows . It benefits a very few and isn't needed . Already have a bugs thread where someone bought sitting and is complaining he can't cancel it after 3 hours .
