I said 10-14 delta. Here are all the trades, that's better than the previous one
You do realize, that when you sold 8 options and with current value, you sold like 1.300.000 USD worth of SP500 on your 50k account. And I dont think you need to ask if this is sustainable ok or anything else. You were lucky times and times again. We do not need to have 2008 to wipe you out. Flash crash or something similar can do that. Margins increase, VIX spikes, but not to your desired 25 level, but imagine something like 50.. If you think this is a strech, VIX went up to 80 in 2008... When you open up a chart, please do not open it for 1, 3, 5 or even 10 years. this is all latest bull market. Open it up for at least 15, better yet 20 years.. And its not delta that is going to kill you, but vega + margin increase on IB + margin increase on exchange when shit hits the fan.. With your account I would not sell more than 1 ES put option, 2 max. Selling 8?!?! I see this all the time on various FB groups too. Most people with 10k or 20k accounts sell options on SPX, which is twice the ES.. Mostly 0DTE trades. And then they brag on 180% returns. Sure, when FED just pumps the money into the system, selling puts can really make you look smart. But I still cannot believe how undercapitalized most people are. I have 100k account and would not touch SPX...
All in all, you were extremely lucky. You can be happy you survived, doubled your account, but now just scale down and maybe you will keep some of it. If you continue with that kind of leverage, I can guarantee you you will not survive….
Sure, when you sold it was worth that much, but greeks are not static.. By the time shit hits the fan, your short 10 delta is now 40 delta. Your short 15 vega is now 35 vega.. Now calculate it again.. Even if you take only delta into account.. What if SP500 falls all the way down to 2.400, like it did (actualy to 2.300) and expiration is there. Your short 10 delta is now 100 delta, because your OTM option is suddenly ITM. And now you must fork 960.000 USD because… Before expiration you also have to worry about vega, which will increase the value of your short option a lot..
