To update, Friday Tsla 799.50 about 1 min before the close. Bought the expiring 800 calls for .15. Tsla closed at 800.03. Sold short stock after the close at 800.35 bought back at 799.50, then added a few more scalps. Had to leave at 430et, so I then filed a "do not exercise" on my calls as they were .03 in the money and finished with no position.
I think there is an additional risk here, if for some reason there is a mistake in filing the "do not exercise" I would end up coming in with 1000 shares. I did go over it 10x but there is always that risk.
Did you not also have to have 800k buying power for 10 calls, or did IB let you swing them with less?
I thought the 800 puts at 3pm were priced very cheaply at <$2 , went as low as $1, before spiking to $7 when tsla took a dump late.
More money in that kind of gamble with less hassle.
And you're right, theres a lot of execution risk in your trade.
