With most mutual funds, it doesn't matter what time of day you place the order, you still get the EOD price.... as a consequence, most wait until near EOD to place their orders. Let's say there was overnight news and a big market reaction... and you'd LIKE buy/sell early in the day... but you can't... and by the end of the day, the price has moved 5-10% (sometimes even bigger moves lately)... so your risk-reward is damaged by having to wait for the slippage of EOD fills. Futures... no problem at all.
This is the whole reason i thought the outside prices would be legit..... i would have thought the outside bid/ask would be arbed to the spot price of the underlying commodity, that is probably why the scam works so well for them.....
