Selling OTM put options. It's like catching falling knives
Basic difference: OP sells cash secured puts, Karen naked with margins.It's precisely what it is. OP will end up in an all-or-nothing position just like playing martingale in the casinos. He's not factoring in the leveraging effect though, that if he's reasonably far out of the money and the option gets within 1 point of his position the IV has likely spiked way beyond the model he has (if he has any) and is likely bleeding out.
Karen the SuperFraud's strategy relied on fraud. Then volatility striked and wiped out 100 million in paper. For reference she basically followed this exact strategy, fraudulently rolling losses to the next month on the HOPE that they'll improve next month. OP is not a fraud (most likely) but is making the same fundamental mistake.
Selling premium in this way is just deferring a bad trade over and over. Sometimes it'll work, sometime's you'll be remortgaging your house. OP is far too confident.
Fine. Just keep in mind that your ultimate success will require a change in strategy when the market peaks and we get into a recession and a bear market. How prescient you are in foreseeing changes in market trend, and how nimble in adjusting, are going to determine your long term net. Your strategy is by no means foolproof. At least by cash securing your trades you won't be forced to sell the Picasso's when things go badly wrong.I would like to add that there is a widespread misconception that selling premium entails some kind of wild risk that only a fool would undertake. I have made the case that selling puts is less risky than an equivalent stock position - it's just simple math really. The important thing is that I have the position cash-covered, I'm not leveraging with margin.
A stock owner loses dollar for dollar with every drop in stock price. What do I, the put seller lose? Perhaps nothing. The time value I collected (the premium) may be enough to cover the drop in stock price while still returning me a profit.
Let's say the premium doesn't cover it. The stock has dropped so far that it's 1 point under my strike, the time value is gone. So I trade the intrinsic value for time value by rolling. I buy back my put for 1.05 and sell one strike lower for next week for 1.20. I now have my original premium plus 15 cents. I have gotten paid to lower my entry point. The stock owner is where he always was. I'm now 50 cents lower with a large premium that is about to pay off, either this week or some weeks down the road, at which point I will have an even larger premium to collect.
It should at least be clear that I have far more control over my position than a simple stock owner. And that means a lot less risk.
What if I sell a credit where max loss is 5% of my liquidity and when I am right I make 1% to 1.5%
So I have 70% chances to be right and make 1.5% or 30% chances to be wrong and lose 5%.

Thanks for presenting your strategy. Here are a few comments and questions.
It's been mostly a bull market. If every time you sold an option contract you instead bought 50 shares of the underlying stock, would your results have been better or worse?
What has been your beta to the SPY, and how does your Sharpe ratio compare to that of SPY? Is something like QQQ a better benchmark?
Maybe your strategy has an edge. If it does, great. Answering the questions above could help you determine how big it is.
Great results, keep it up.SP500 CAGR is about 13.7% for the last 4 years, you are doing about 5% better.
