Thanks @AndrewAMD.

*sigh* So, not only no simple answer, but one must also pry information out of the broker, and trust it as well...

Thanks.

Yes. With IB, leveraged ETFs have special margin requirements that basically compensate their leverage. Some info here: https://ibkr.info/article/1124

Thanks @jcl.

Clarification: It appears from IB's write-up that this/these is/are government/exchange rule/s. And so not IB's sole decision, but all brokers must follow, correct?

Thanks.

Yes. The brokerage also has the right to employ even stricter rules than the exchange rules.

Thanks @AndrewAMD.

Let's assume for the sake of argument that I'm human. Meaning 2 things: lazy, and (even when not lazy) make mistakes. Since Zorro is not set-and-forget, I regularly monitor. Within that framework, for trading stocks, ETFs, etc. is there a better choice amongst:

- Expend the (on-going) effort to research & set each & every Asset at the correct Margin, expect that Results will match Test, and risk mistakes
- Be lazy and pick a Margin value (1, 2, whatever) and just use it for all Assets, accepting that Results will not match Test, and possibly Trading with Capital less than CR for added safety

Thanks.

I have a different lazy option: Set the leveraged ETFs to 1:1, and the ordinary ETFs and stocks to 2:1.

Thanks @AndrewAMD.

Given that I'll sooner or later accumulate some # of mistakes, how bad will the risks and/or results be with leverageds at 2:1 and/or ordinaries at 1:1?

Thanks.
