Maybe you all would like to join a live streaming session where we use TOS analyze tab to show you how I stress the account. It's all about keeping the size small. You can never think you've found the holy grail. If 1987 happens again, I'm still in business.
I'd join too cause I don't think I'd share that view - I think there's a good chance the account would be toast.
Here's a quick summary where I get lost in the math how you would survive. Feel free to point out wrong assumptions on this calculation - it's a back of a napkin but it still illustrates the constraints.
Let's say you've 15k in your account. (multiply with the real number - the ratio is the same)
Let's say you sell 1 SPY 20 delta straddle - to stick with the analyze tab that would be aug/18 expiration 252 calls 239 puts. On 15k a 1 lot seems pretty small on SPY the initial margin without portfolio margin is about 2k. So realistically you'd sell more than a one lot but let's carry that example through.
This produces a theta of 4 bucks ~ so with 250 trading days you're looking at a potential profit of ~ 1k/year depending when you're rolling (and I realize that theta accelerates as you get closer but so does gamma and that non trading days also slightly contribute to theta) - so let's stay with this example. That's less than 10% annual return. The way to increase that return is closer to expiration options or more leverage - both increase the risk - so let's ignore that for now.
Now let's stress this 1 lot on the analyze tab and simulate a 22% drop and a volatility spike to 152 (I grabbed those numbers from here
https://www.tradingview.com/chart/SPX/WwN6HHVe-Revisiting-October-1987-Stock-Market-Crash/)
So I adjust volatility on the Analyze tab to 150 and the stock price to 191.
Here's what happens:
The P&L loss is 8644. The margin requirement goes from 2k to 9420.
So your 15k account would be down roughly 3k (as in 15k at the end of the previous day -18k that you'd be responsible for the end of that trading day). You'd be pushed out of your positions at the worst price/spread and you'd hate your brokerage forever. Here's what happened to the ES spread (look at the bid/ask of the e minis)

I traded through this (listening to it now still gives me goose bumps) and got lucky. Hear him quote the spread at 4.40 so in the middle of the video) - when the e minis had a 10 point (not 10 tick) spread the option bid/ask was about 50 points. You don't see the option spread but you hear him quote the pit spread. At that time also TOS was completely overwhelmed and my platform shut down - IB handled it ok since they don't work with tick data but sample the quotes. Without IB i'd have lost six figures - with IB and mostly luck I managed to contain the loss to less than 20k. Anyway - that day slightly traumatized me but going back to the spread - That's about 25 ES points per side (or another 2bucks 50 per SPY contract) that you'll pay off the mid price when you're eliminated that isn't factored into the above calculation.
Bottom line is I like your spirit and I don't care much for your money (I don't share profits or losses with you) but just be aware that the analyze tab isn't as mighty as it may seem and this is a systemic risk with tastyworks as a brokerage cause you and many other followers will either bring the firm down or all be liquidated around a similar time since their styles are very similar and most of the risk algos run across all accounts.)
