So in short, if you are looking to trade US futures, assuming you qualify for margin permission, you will be able to do so utilizing margin.
We were having two parallel conversations. The first is that I looked at the wrong section and other than Investment was Margin Portfolio as an account type. I went back and then saw Leveraged Trading as an option. Leveraged Trading is what you are talking about, and you are correct in your statements.
The issue as I mentioned above is that when I was paper trading ES I was having the full $ 160k taken out of my balance. I sold and then when trying to buy back I got a warning of insufficient funds in my AUD 380K paper account to close the deal. I had this issue with FX in my paper account (see image), where I could get into a trade and not get out due to 'insufficient cash'.
So from my perspective ES was full price unless I had a margin account, which when I checked gave me Margin Portfolio as an option in account types, which the requirements are as stated accurately by me, but also indicated correctly as not necessary by you.
So my entrenched irrational fear is that I get into a trade and can't get out, as it has happened in my paper trading account numerous times with FX and futures. I think it is a AUD and USD cash balance issue, but surely this should be documented somewhere.
So it would have been nice as a rep of IB for you to have taken the time and interest to not just make short contrary statements but said:
"you don't need a margin account for futures you can have a cash account and trade at the listed price of 14K as there is margin already built in to the contracts, if you want a margin account you can apply for a Leveraged Trading account which requires 40K+ per year income only. The 100K you refer to is for Margin Portfolio which is a different type of account in a different account management option".
As for the full price being taken out of the account, we could have moved on to that.
