Down 7000 USD on 200K shares.
I have been suspicious something ws wrong since yesterday that I received too many fills on the long side and also significantly higher fills than normal. I think I found out that I put the fair value as -3.1 as supposed to + 3.1.
OPG's are much more of a gamble than ever before, and they're addictive and deceptive....
addictive because ....
1) you think that by preparing the excel spreadsheet with fair value estimates are the same values that the specialist is thinking or using....
2) by doing all those premarket activities, you are pretty much assured (guaranteed) of a decent gain or break even
3) all those prepatory activities brings you closer to where the markets will be opening...and there's no guarantee that all the interest in stocks will be displayed or represented by the S&P values that are used
deceptive because ...
1) you can't get yourself off the practice of these huge dual sided (hedged) "poof" orders that dissapear after the OPG round
2) you think that by just varying the range of stocks you can pretty much get and edge or start off with a nice gain
3) won't get creamed on a huge losing day, like so many others who have sworn off of these methods...
One usually learns the detrimental effect of OPG's when one crashes with a huge loss that's uncontrollable and is forced upon you as YOU put the orders in, and hoped that the specialist was wearing kid gloves that day...
sorry for the losses, but this downside has been discussed many times on these threads....
snake oil, well, that's a conclusion you'll have to draw...
