@draft730 , ignore the haters, and the most sensible responses you've had so far are from drcruz and SweetBobby.
I'm an option seller myself (over 10 years) but I also trade a lot of other things.
Firstly, congrats on your returns - you've more than doubled your account in 3 years.
Secondly, if you can survive Oct-Dec 2018, then you're better placed to handle future meltdowns. That pre-Chirstmas fall was the heaviest for like 90 years and Christmas Eve 2018 was the worst Christmas Eve since the beginning of the time for the SPX.
You admit that you escaped that period somewhat due to luck as opposed to any skill, but luck helps in the game.
Going forward, here's what I would suggest :
- as previously mentioned, limit your exposure (reduce lots sizes). This is THE biggest reason for traders blowing up.
- diversify using countries - sell puts on different countries indexes. Sure, worldwide equities are heavily correlated, but the London based FTSE and Germany's DAX can often diverge from the SPX.
- diversify using asset classes - sell options on currencies, commodities, treasuries, metals etc. However - be VERY careful with commodities, as some can be very volatile (eg NG as mentioned earlier in thread).
- reduce risk using variety of short strategies. You don't just need to sell naked puts - you can do credit put spreads, ratio spreads, diagonals etc. They offer controlled risk.
Tread small, tread carefully and your returns may not be what you have emotionally become accustomed to, but you will make slow and steady gains. And be able to sleep better at night.
Good luck.
