Improvements to Trading System
We’ve launched a significant improvement to our trading system today that makes trading on UpDown even more realistic: partial fills.
So far, all orders were executed in one batch regardless of their volume, allowing for substantial volume trades of even lower volume stocks in seconds. Now, orders will get executed based on the volume that is traded in the real stock market.
Small orders of high volume stocks (i.e. 1,000 shares of Apple (AAPL)), will still be executed immediately. However, the execution of a large order of a low volume stock will happen over time as the volume becomes available.
For more info, check out the new paragraph on partial fills in our help section.
Looking forward to your feedback!

you change the view of the page and now trading is complicated as they do not work

Nice touch re partial fills
Next improvement needed: Change order, especially on limit orders, where one wants to merely change the price or quantity.
Urgent Fix required: In my account, SwingUp, somehow your system executed a single order twice: buy 270 APOL@74.40 causing my account to be on margin call. No-one is looking at emails sent to contact@updown.com. I have not been able to trade in the account for 3 days, due to this. In addition, one of the APOL buys got charged a $200 commisssion. Weird!! PLEASE FIX THIS ASAP, and contact me to let me know when I can expect my account to be back to normal. EmbleA@aol.com.
Thanks, Anne

I like the realism, but I have a sell limit order in at 19.60 on a stock that is at 19.69 currently, so shouldn’t I be getting the better price as I wait for these five hundred partial fills to go through. I mean, realistically I would be getting partial fill sales through on a limit order at my limit or higher and buys at my limit or lower. Please explain. Also, why didn’t I get my dividend on SSS this morning like I usually do. It was .64 cents a share payout and should have been a bundle of cash considering 20% of my portfolio was in the stock.

Are we not allowed to cancel a limit buy order after a partial fill? I have a limit order on F, but after it was half filled, I tried to cancel since the price shot up. It says it is canceled, but on my Port. page it still says pending. ??

Never mind. I see the partials going through on the way up. Thanks, but I still want to know what’s up with my dividend on SSS.

If you are going to make this more life like, please add the ALL or NOTHING options to high volume trades. I was “sick” the past two days of not being able to purchase stocks at Limits because I think you were implementing this new feature. There were several stocks that I could not earn money on because of this. Also, we need to know rather clearly if there are multiple fill commissions for purchases that take time with volume. This is very important because commissions do effect overall success for day-traders. Please make the features more world-like by using an ALL or NOTHING designation along with a buy that is executed at asked limit price which would only wait on volume - not a NO BUY situation if the volume at that particular price does not going on simultaneously on the exchange. I really enjoy this system and would appreciate you taking this into consideration. Thank you, Robert

Will accounts be charged the $100 commission each time a partial is executed. So say I had an order for 100K shares of XYZ but it took 10 partials to fill, is that a $1000 commission, or $100 when the full order is filled?
Thanks

So basically, its making high volume stock your best bet for larger orders?

What about commissions ?
Are partial fills still 100 USD in total or more, ie. 100 USD for each fill ?
April 6th, 2009 at 11:06 am
And see you are charging full commissions.
April 6th, 2009 at 1:20 pm
I hate it. thanks

I hate it

The Facebook app needs some work, it probably should not have been released yet.
One, the Invite Friends page loads a blank page.
Two, why is it that the Facebook portfolio and UpDown portfolio are not connected? That makes no sense.
You should force people to visit UpDown to make their trades, etc. and then simply integrate the UpDown portfolio information into Facebook. You are losing out on hits and revenue the way it is set up now and its a pain to do both, so I’m choosing to do the Facebook app, which means I won’t be viewing any of your adds anymore. Should def think about integrating the two.

I have noticed that ever since this enhancement was installed my portfolio screen does not list all data is listed for my short positions (i.e. missing “price paid” and “total gain”)
April 8th, 2009 at 4:39 pm
@Everyone: Sorry for not replying during the last couple of days. Regarding the commissions: you’ll be charged only once for a trade, not for each partial fill.
@Anne: I hope your portfolio issue is resolved, if not, please send me an email to michael@updown.com and I’ll look into it. Thanks also for the “change order” idea.
@ Christopher: did you get your dividend by now, if not, please send me an email to michael@updown.com and I’ll look into it.
@greenvan: Thanks for the “all or nothing” idea.
@Ted: we have not launched the facebook app officially, we’re still testing it. Thanks for letting me know that the invite does not work anymore. We’ll fix it asap. When you signed up, you actually had the option to login with your existing UpDown account. If you want to, we can manually get that done - please send me an email to michael@updown.com if you like us to do that.
@Hal: We did not change the portfolio view - you can still see the price paid and the total gain by clicking “total gain/loss” on the top of the portfolio page.
Let me know if you have any other issues and feedback.
Michael

ya a little notice i lost 60 grand b/c of it they should of told use a day a head
April 9th, 2009 at 12:09 pm
My reply: Awful. Makes you have to pay even more attention to everything, spend more time, get less out of it. Good grief.
April 9th, 2009 at 12:12 pm
This is a dumb feature - half of my trades on this site don’t get filled as it is. Now I’ll get half of the partial trades completed = roughly 25% will get completed then, right?
Then you have ridiculous margin calls and additional commissions based on your site’s errors. My patience is wearing thin…
April 9th, 2009 at 1:01 pm
totally hate it, slows down the trading further. In “real life like”, I wouldnt be willing to pay commission up to 4 times.
April 9th, 2009 at 1:59 pm
@avie: commissions are charged only once for each trade whether partially executed or fully executed. I don’t understand why you would be charged 4 times.
April 9th, 2009 at 2:12 pm
Why did u changed!!!!!!!!!!!!!!!!!!!!!!!
April 9th, 2009 at 2:14 pm
We’ve changed it to make the site more realistic.
If you try to trade 5% of the daily volume in the real stock market, your trade will either be executed at a bad price OR take a long time to fill.
Our goal is to make UpDown as realistic as possible.
April 9th, 2009 at 4:24 pm
This is a great idea! To all those that don’t understand it, too bad! You’ll figure it out over time. It evens out some of the unbalance in account liquidity, which is fantastic. Significant differences still exist between this and the real markets, but this is a step in the right direction for sure.
May 3rd, 2009 at 4:57 am
Great change to make Updown more realistic.
I wonder: What large differences still exist between Updown and real markets ?
I know it’s sometimes hard to be able to find stocks to short. This is easier on Updown than real life. Aside from that, I don’t see any differences.
Would like to hear ideas and inputs..
June 10th, 2009 at 3:02 am
Actually wats the main difference between these systems…? i wonder the differences. Anyway Nice info to share with..Thanks
July 12th, 2009 at 6:13 pm
I guess I agree with you but maybe if you explained it just a little more I could learn more. Thanks in advance.
August 30th, 2009 at 8:20 pm
I never ever post but this time I will,Thanks alot for the great blog.
September 11th, 2009 at 11:29 pm
Wow, good to know that, I’m happy for that! Nice post, very informative, but can you post another one regarding this topic? Thanks a lot, keep up the good work. Nice site.
