Do you mean that Penson follows exactly the TIMS requirements and does not require higher margin? Are there any brokers except for Penson that use exactly the TIMS requirements? There are rumors about Penson's stability...

Thanks for the link, but I am searching for brokers that don't follow TIMS pretty closely but exactly follow TIMS. And I saw in a TOS paper PM account that the required margin may be much higher than TIMS.

Are there any brokers that follow exactly the TIMS margin requirements used by the OCC regarding US index options (such as the SPX) in a portfolio margin account, as shown in the OCC website (https://cpm.theocc.com/tims_online.htm)? I understand that regarding a PM account the brokers will...

Actually my trades may involve also SPX. Why can a floor broker improve my results regarding the SPX? Is it connected to the SPX being traded only on CBOE in which the trade is not fully electronic? Also, you mentioned that I'm not going to do any better than a firm like IB -- do you think...

The reason I asked about prime brokers is because they say they can get my orders filled even when such orders are not filled through the electronic markets and the complex order book on the exchanges; in such circumstances, they say they can make other parties interested in filling these orders...

Hello, I would like to trade a large amount of spreads of a relatively illiquid long-term options and I encounter problems in getting my order filled. It should be noted that such options have open interest of tens of thousands contracts but the volume is pretty slight. I currently trade...

See the following link (regarding SMART guaranteed orders): http://ibkb.interactivebrokers.com/node/1683 Please let me know if I didn't understand it correctly, thanks.

You raised important points and indeed only IB may have answers. However, I understand from IB website that in smart routing they take the risk of execution problems, so it may mitigate substantially any risk of partial or double execution.

You mentioned IB -- in their website it is stated that their smart routing represents each leg of a spread order independently and enters each leg at the best possible venue (http://individuals.interactivebrokers.com/en/p.php?f=smartRouting). So I understand that when I enter a spread order...

Thanks for the answers. Just to clarify -- if "smart route" may only send the order to a single mm and therefore the order may not be executed unless the mm sees value, what is so "smart" about a "smart route"? According to the nature of its name "smart route" should imporove the chances of...

Hello, I have two questions related to order execution: 1. If I submit a spread order (say, put vertical credit spread with two legs) does the order will be filled only if there is an exact opposite spread order that fits the spread limit (that is, put vertical debit spread with the same...
