😄 At least you froze. I wet my pants.

I had a couple of calls with them. Unfortunately they are not very willing to arrange a special offer for SO members. They feel they're relatively cheap and have the idea that their content is highly valuable to their customers and therefore justifies their pricing. After a few back and forths we got nowhere, they were very welcoming to signing a referral agreement. I send their offer to Kim but, not surprisingly, he wasn't willing to work with them on that basis.

@QuickNick I've never tried. I suspect my current level of trading wouldn't pull much weight...I'm basically taking a pause at the moment.

Thanks for the prompt feedback, @Djtux! Yes, a separate page on RV charts would be fine, or you can just add an advanced options for how many day to plot after earnings. And, Thank you for the advanced options tip, I hadn't realized that was the actual function of that list. Should have played with it.

Yes clicking the line in the chart only hides it, but does not trigger the average/median RV line. It's a technical limitation that i have for now, you need to go to the "Advanced Options" to select the cycles you want to ignore.

Thanks for taking the time to report the bug. The IV chart x-axis is bugged. That's new, i will have to investigate, probably something changed in the library i use to display the charts. In the RV chart page, if you click on the "Advanced Options", you can select the cycles you want to ignore then click "Run backtest" and the average RV line will be recalculated : Would it be ok if it's a separate page for the RV chart ? I would prefer not to make the RV chart pages more complicated than it is right now. For the return matrix, that could be done with a flag to display "before earnings" or "after earnings". I prefer that to avoid having a giant unreadable matrix. I can add all that to my very long todo list, so please be patient.

I guess it happened to most of us at some point in our career.. Happened to me over 10 years ago but I still remember that sound... tiktok tiktok tiktok tiktok You know what that sound is? That is the sound of IB liquidating your positions.. one by one. You hear that Mr. Anderson?... That is the sound of inevitability...

To explain, here's what happened. Your short 122.50 call was a promise to sell someone the stock at a price of 122.50. Someone decided to take you up on it, and "bought" the stock from you. So they paid you money in exchange. Since you didn't really have the stock, the brokerage fulfilled that purchase on your behalf. You now owe the brokerage that stock, since you've technically "borrowed" it from them. As @Yowster advised above, in order to make sure that the market doesn't swing against you, make sure to do the following as one step - as a "combo" order - or, at worst very quickly and close together.: You'll have to buy the stock from the open market (at a higher price now) to give back the stock you "borrowed". To do this, you will be using the payment you received to fund part of the purchase. There's obviously a gap, since the current price is higher than the 122.50 price. To make up the difference, the rest can be mostly paid for by selling the Long call you hold. The remaining balance you'll have to pay from your own pocket. In other words, sell the Long call, and pool that money with the money you were paid for the stock to buy the same quantity of stock from the open market.

Im all for this as it would be interesting to see but I think @Djtux has about a dozen more urgent things going on right now (like changing average returns to median returns in the scanner hint hint I wish we had the data to be able to run these tests on our own. I think there is even a pattern between the day of the week a stock reports. Especially for some of my strategies where we hold through earnings. For example, trades opened on a Thursday with an expiration the next day on Friday behave a lot differently then trades opened on Monday and closed on Tuesday. I am sure some hedge funds and MMs have all this data and use it against me

Just as another data point I pay 55c per contract at ToS.

I dont know the others - with few exceptions I have the feeling execution on TW is really very good. Never perfect but that is not expected.

I would add fees to the list of drawdowns. In the past 2 months I accumulated around 1,100 USD in commissions and fees on tastyworks. That is almost 50% of my profit. Until now I have not been aware on how huge of a drag commissions and fees are.
