Watch out, world. Now I'm apparently an options expert.

Forgot to mention that the above graphs are for a 50 delta call. Similar trends would presumably hold for other deltas and probably also for puts.

presumably if I "pass" the quiz, they will give me level 4. Of the 150 questions that I finished, I only got 5 wrong, so hopefully I will be good.

now feel free to beat me over the head with it

I moved all my "test" money to TD Ameritrade. It's a good platform, but I'm having trouble getting access to "advanced" options (e.g., undefined risk). They are making me take an options course with 180-question quiz. I finished 150 questions yesterday, stepped out to eat dinner, and find...

I got access to ORATS (yay!) and finally have some historical options data to wrap my head around. I have been studying the slope of the IV curve versus DTE. For the SPY, the average curve over a year looks like this. Rather than do a curve fit, I just define "slope" as IV(40DTE) -...

And I was trying to trade about 15 securities while working a day job. I was overwhelmed trying to "think" about each exit & entry. That's a lesson unto itself (trade less if you can't fully understand each trade)

You give me far too much credit. :D No backtesting, but I should, because I've started using the ORATS API. Love it. Many of my choices were related to liquidity. A 120 DTE, 75 delta long call is easier to roll than a 500 DTE, 90 delta call...and vastly more capital-efficient. And still I...

I traded the poor man's covered call (substitute 1 long-dated, deep ITM call option for every 100 shares of long stock) extensively for about a year, on multiple securities. I was not pleased with the results (not that I went off the rails). It was a hell of a lot of work to end up a couple...

Thanks for the info. If you feel comfortable answering...are you typically looking at anomalies that persist for minutes, hours, or days? Or all of the above?

Thanks for adding some color to your method. And huge congratulations - it's cool to see someone who knows what they're doing, having success. Are the hedgers the "dumb money" here? e.g., they buy puts at any price. Do you have some special method for determining where the dumb money is...

Check out guru's journal. Holy crap, he is getting like 20 percent annualized with almost no volatlity!

wow, this beats the hell out of a money market account!

Hey, didn't know you are in the Springs! I'm up in Greenwood Village. Balmy November we are having. ;-)

haha, I bought 50 shares of Rivian (RIVN) at $99. Sitting at $165 now. I should have bought 100 shares, so I can sell covered calls against it. To delta hedge, I sold a Dec 17 call credit spread (165 short/210 long) for $12.80. Takes my net delta down to ~25.

To use the apps scripts, go to Extensions->Apps Script. Then you write your code in javascript. Here's the Black-Scholes code. This function just returns the option price, greeks, and IV for one day. It pushes those values into a column. You wouldn't want your spreadsheet to call the...

I am just using an old windows 7 desktop with 4 GB of RAM. These google sheets are memory hogs. Might be tough on a machine without sufficient memory.

Trade #6: SPY call diagonal debit spread, slightly bullish bias. Profitability range at 6 DTE: $463-$482. SPY $467 at open. Delta neutral. Slightly vega positive, which is OK with me, as it will cushion the downside, should stock move against me. theta/gamma ratio flat over life of trade...

Exit trade #3, (1 lot) diagonal SPY call debit spread opened on November 2. Cost: $7.18. Sale: $8.17. $0.99 profit. Trade had a slightly bullish expectation Volatility and SPY stayed pretty flat over the trade period, so the trade worked more or less as expected. Trade was positive...

Thanks. It's too bad that the trader who developed these google sheets tools (me) doesn't have a clue about real trading! :D To solve the Black-Scholes equation, I actually use google apps script, which is akin to visual basic for excel, but more user friendly (javascript) I'm actually...
