Good one,
But I'm being serious, back in the day (decades ago) I wrote a market simulator using GBM and prevalent realized volatility values to simulate 1 minute intraday moves. Then I applied my complex algorithm (coin toss) with a few more parameters (like closing and stop criteria) and I watched my system achieve returns in excess of 40% some simulated days, other days I got like 120% return!
Of course over a full 1000 simulated days run, I was at break even
But I always wondered if you could do something like that, get a few series of winners and then retire
