Etrade Portfolio Margin

Does anyone have any experience with Etrade's portfolio margin? Do they track the TIMS margin closely? Thanks for any info.

 

Are there any others (besides IB and now E-trade) that offer portfolio margin?

 

We offer Customer Portfolio Margin through our relationships with Penson Financial and ML Pro.

 

So we have IB, etrade, and Victor.

According to theMargininvestor (dot) com:

ThinkorSwim offers portfolio margin (I'm not sure if it does for new customers post-TD merger).

OptionsXpress (now Charles Schwab) apparently offers it as well.

Optionshouse offers it (but apparently not to retail clients)

Lightspeed

NewEdge

I also read on a forum post here that Vtrader offered CPM.

Any others to add?
