streetsmart edge will be discontinued as far as I can tell streetsmart edge was nice because it was easy to use. thinkorswim is more robust but it is not as intuitive and takes a little more time to learn (as there are more features)

Now that thinkorswim is on Schwab, the level 2 quotes only display ARCA, NSDQ, EDGX. Is there a setting to get the other exchanges and market makers? similar to how it was before when it was on Ameritrade. ... nevermind, the quotes appear correctly after 7am EST

Their website says $0.65 per contract. Anyway to lower this? I also figured out the lower priced contracts below 0.13 get a discount of 0.05 for each 0.01 lower ie. 0.12 is $0.60 0.11 $0.55 etc.

I had this issue with IBKR in 2003, I bought 200 shares of something that was not traded much in the premarket session that was offered in the order book, which was currently $10 below the current market price ($2000 instant winner). They called me and broke the trade and refunded the commissions.

There is little risk in selling those, but it "wastes" all your margin until they expire.

each naked straddle uses approximately 260k of day trading buying power. so 12 straddles is about 3.1M of DTBP DTBP is 4x, so need ~780k of margin.

I currently just enter straddles at my discretion, when I think it is a sideways day. (mostly selling strangles) I was just wondering what would the results be if it was done every day for a long time.

I sit in front of the computer all day :) nothing is automated
