Correct. Even though Sterling Trader Pro offers a short locate tool (we currently offer 3 premium locates on that and Lightspeed Trader), STT never added the ability to query that through their Api or the Lightspeed Api. The function was never built in. We have a new Api we call The Lightspeed...

Well, you are entitled to your opinion. Unless option markets are penny wide, I see a large number of prints in-between the bid/ask spread and the cost savings can be material with or without rebates. I wonder is @ORATS has done any studies to show the percent of executions done between the bid/ask?

I can only tell you what fits my trading and extensive experience in options. This does not mean it is best for you. While trading volatile symbols, my buy entry price would typically be 25% of my planned size at the mid-point. Then I would enter 25% on the bid. I would allow time to pass, the...

konkhra- Your profile says "Romania" We have both individual and OU accounts from Romania. My contact information is below. Just email me any questions I can help with.

Buying on the ASK and selling on the BID is NOT slippage. You are also talking about a symbol with a notional value of $281,700. The bid/ask spread is VERY low.

It was common to have that strategy. The specialist in front of me once told me, "If I sell an option at 1/16 (yes, a long a time ago) and it goes to $1.00 and expires worthless, it was a good trade". That worked better in the 70s, 80's and 90's when options were typical over priced, as most...

There was a saying on the AMEX floor, "whoever dies with the most toys wins". I do not live by that. Your friend passed away rich at 62, that is horrible. I do not want other traders here to feel like they need to trade large to do well. Make money every week and every month. Have fun when not...

I’m sorry he died so young. I’m not that familiar with the Chicago traders. Interesting you described him as the “largest” Option trader, not the most profitable. At his peak, how much AUM was he managing and was his forte options on what futures?

Know I did not. And who was that?

May I ask, does it matter what exchange short selling occurred at? I would think end of day data of short interest offers more information, as those shares require a borrow.

This file does not provide that?

My other comment was when you buy a 1 year T-bill, you lock in a discounted rate for that term. When you put on an option position with stock, your long/short rates can change, so when you price a conversion going out 1 year, you have to use what you expect not only what that blended rate will...

I have said that Rolex is never my first choice. However, I think this is hot. 1908 https://www.rolex.com/en-us/watches/new-watches/1908

I agree. In addition I rarely see back testing match real trading and "oddly" real trading is never a higher profit and almost always lower. And 10 years to study trading with no income sound like getting a PHD with loans to carry you over, only to work a job making $30K per year. Except maybe...

At NYU, I took BASIC, Fortran & Cobol programming. This was from 1979 until about 1982. I liked and picked up BASIC & Fortran very quickly. Got "A"s in both. Cobol and I did not get along. To be fair, I was on the Tennis team at the same time and missed some classes. I had to change the course...

Well, that made me feel oddly dumb.........

No. It is equivalent to shorting the Put on the same strike as the Call for risk and reward purpose except you get to keep any dividends. In essence, the same as a cash secured put.

Skipping the very expensive service Databento can provide, which is not for a retail trader with a trading platform, depth of market is not available on any display I have ever seen for OPRA feeds. And your premise of the value you get from seeing option bid/ask outside the current NBBO, I would...

OPRA only refers to this as Non-Pro or Pro Device. I thought to get real depth of market with OPRA, you need a raw feed.
