I saw this on Interactivebrokers TWS screen. I checked margin, it seems only 25% of the 30 shares of the stock is needed to fund this trade, so I think it is not truncated number of shares there. Is IB TWS an ECN ? Sorry I have almost no idea of NYSE mechanisms.

Hi, I usually only trade futures, but just now I tried to buy 30 shares of certian NYSE stock as I saw it was offered on the screen, but the trading platform feedbacked that "NYSE dosn not accept odd lot order" . Does it mean I should buy at least 100 shares of stocks at NYSE ? Then how could...

You can always plot your own, if you can do some basic coding.

I wonder why IB keeps releasing new version while some old versions can get the job done perfectly.

Maybe Ib can just release the stand-alone TWS v876, and leave the choice to the clients, just same as what they dealt with v873/4/5.

I also have been waiting for the release of stand-alone version of TWS v876 for a long time. I cannot use v873, v874, v875 due to the same reason as Kiwitrader mentioned.

The point of kelly's formula is not about risk management, the point of kelly formula is about maximization of the profit. Though in practice I have been very conservative , but I still have to point out that in mathematical terms, there is only right kelly f% for the maximal output of any...

I would say it is more like the pricing of a binary option

Are you in lack of cash ? :-) Keep the deal, it's USD10 at the end of this year.

I read that paper of J Kelly years ago. I noticed that most authors ( including J Kelly ) on money management prefer to use gambling as an anolog to trading. It is OK with that . But traders must bear in mind that : trading is different with gambling . In gambling if you lose a specifit bet...

what is f in the original post? Accroding to Ralph Vince ,f should be the percentage of the account to be risked in every trade, rather than the percentage of the account to be put into a trade .

How to judge "volatility is back to normal "?

Seriously, so it means auto login is impossible with this hardware encription introduced ?

Recently I got password card from IB, which I think is a good method for protecting client's account. But I have one problem now : I used to use a program called "IBController" to auto login to TWS, but with this new plastic card, it seems impossible to auto login any more . Does anyone...

Nifty looks to be a great instrument, look forward to its debut in TWS.

I see, thx Def.

Fair enough. But Def could you advise how frequently you will change the margin. This morning I check margin and found it is now 78% of the HKFE margin requirement again. ( Yesterday it was of less percentage, and HKFE margin for HSI is same for today and yesterday.) Hopefully you only...

Hi, guys So what have you done or what will you do in this summer vacation. For me, the prolonged super volatility has prevented me from getting out, though I have been looking forward to this summer vacation for a long time. Anyway as the summer is leaving, I decided I should let go my...

One or two weeks ago I called IB HK office when I found discrepancy between the margin requirement indicated by IB website and TWS "check margin" function, they told me on that day that HSI margin was set to 78% of the HKFE margin requirement ( normally only 50% for intraday trade) But when did...
