I think the issue is that the shares are currently your collateral for your margin. If you sell CCs against them, the CCs are using the shares, leaving no/less collateral for your margin. (You can't use the same share value to cover two different positions.)
yep
The only orders I had open were for closing some long positions, so those would not have margin requirement either.
This explanation makes sense. I have very little cash so my margin all comes from shares owned and I do have some put spreads which require margin. Removing the shares to cover the CC would reduce that base. Thanks for clearing this up. The message I got from IBKR did not make this connection, it was claiming my "Initial Margin" would go up.
are you using Reg-T or Portfolio Margin?
you can sign up for PM and will probably loosen up the requirement a bit. although the concentration of composition of your acct still holds a lot of weight in the buying power and margin calc’s (for example, if you have a handful of positions and all of them are TSLA stock and TSLA options, vs. a more “diversified” portfolio.
Are these shares bought in the last couple days that haven't settled yet?
Edit: Actually, seems like a bug in IBs trading platform. Lots of Reddit threads on IB sometimes needing margin for CCs. This thread mentions trying to put the order in through TWS instead of the app:
im unsure if it’s a bug…one would have to examine the exact use case to figure that out. meaning look at all the positions and values in the acct and the credit profiling output, etc.
the first answer in that reddit string you pasted explains loosely how it works, in theory, although in reality it’s much more complicated than that…and automated at IB.
and it doesn’t surprise me the IB may increase the requirement for meme stocks (as someone mentioned).
although i’m not sure what’s the current requirement is on TSLA, i’m pretty sure it’s not elevated at the moment (i haven’t received an email on this in a while — which probably means it’s around ~30% day to day)
i also find it hard to believe that orders from mobile don’t work, while orders from desktop TWS do. sounds fishy. IBs automated credit manager system, by design, overlays all trading platforms. it has to, because that’s what determines all the critical values (pos value, buying power, net liquidation value, margin requirement, excess liquidity, etc, in real time). it can’t be different set of calcs just because i’m placing order from my phone.
i’ve never seen this in many years of trading at IB (and Fidelity), which of course, doesn’t make it untrue either.
but that would be a big bug in my opinion, and one that would be fixed very quickly due to the severity of outcomes if true.
