Mike,
My prime account is with Bear Stearns, and here's their cash flow of the
example position, which is different to what OptionVue seems to indicate.
Buy 1000 QQQ @$40.00 $40,000
Sell 10 QQQ FJ @$6.60 ($6,600)
Margin amount 50% of QQQ ($20,000)
The debit balance of the account is therefore $13,400 or just under 35% of
the value of the stock.
Presumably OptionVue is using Reg T rules, but they're perhaps misunderstood
or erroneously calculated, or both.
I don't think your calculation of margin for short puts is "real-world."
Using Bear Stearns again as a guide, they'd want about twice the amount of
the credit as collateral for the trade, and would not allow any of the
credit to offset that collateral requirement. That's probably not atypical
for a naked trade.
Considering the above, I still think that the margin requirements would be
around the same for naked puts or leveraged covered calls. And if there was
a way in OptionVue to override it's interpretation of margin requirements,
the profit graphs should be about the same.

Colin,
I fed your position into Option-Vue with yesterday's closing prices.
According to Option-Vue, you'd pay $34,805 (stock price minus call premium).
This is the simple part. The software further indicates an initial margin of
$18,000 (gross) or $16,805 (net). My reading is that the customer would have
to put up this sum, too, but I may be wrong here. Perhaps Mr. Lothian can
help?
In any case, the equivalent naked put position only requires a margin of
$5,000 at current prices which I hope you will agree is considerably less
than the stock price even without the margin for the calls, if any.
Best wishes,
Michael Suesserott
