As a retail knowing many fellow retails doing "buy and hold", we don't ride it out, we tend to capitulate and get out at the bottom. Otherwise, there would be a lot more millionaires next door.
Here's the problem with that solution. What do you do if you stand down and the next trade would have been a masive winner? When do you get back in the game? You can't possibly know what the outcome of the next trade will be. FWIW my solution to a losing streak is to reduce my risk and scale into winning trades. Capital preservation is my #1 priority. If you don't bet you can't win If you lose all your capital you can't bet.
So what is the number of losses in a row you can take without being considered a gambler? What is the maximum number of losses in a row you have taken? And isn't a gambler with an edge a winner?
So you've had 17 losses in a row? I'm sorry but if you have 17 losses in a row you need to scrap that strategy. Period. Which sounds like what the guy in the article did. I'm a swing trader but I've NEVER had more than 4 losses in a row. If I had 17 losses in a row my account would be toast and it would be the end of my trading career.
I'm not sure he scrapped the strategy which is to day trade penny stocks, I think he adjusted his risk control, stopped revenge trading and took only trades that fit the original strategy. I'm also a swing trader (stocks; long only) and 20 losses in a row would result in less than a 15% drawdown in my account.
I suppose, Taking 1% risk per trade gives me a position size of around 14% of my account. If that's piker size then that's me.
