That the trader returns to the market for a different reason(s) is unrelated, isn't it? <br /><br />It would not be sufficient when the utility becomes negative, but for some strategy a trader would *not* return to the market.<br /><br />Are you saying that such a strategy would exist and be sensible?Vivek Nallurhttps://www.blogger.com/profile/08225787758046567554noreply@blogger.comtag:blogger.com,1999:blog-4609531859468647096.post-24990507765114534842009-10-02T08:27:23.561+01:002009-10-02T08:27:23.561+01:00Incidentally this blogger interface isn't very...Incidentally this blogger interface isn't very nice.
