I guess I envisioned a "non-structured" trader as someone with a lot of small wins and a lot more small losers or a lot of big losses. When you say "non-traders" with big gains I may agree with that. I know people who didn't know jack shit about the markets, but they bought Facebook or Tesla at a lucky time...only cause they've heard of these stocks being mentioned a lot...no other reason!
Here goes my two cents worth,The lucky guy that bot Tesla was lucky he didn't have a trading plan. If he had it would not have permitted him to purchase Tesla.When you develop your trading plans you are developing a plan that really limits your ability to see most opportunities the market provides.When the hunter gatherer set out to kill his dinner he didn't tell himself I'm gonna kill a rabbet he more likely said to himself " I gotta kill somethin to eat tonite. When hunting in the market stay open to whatever the market indicates might be available and take it. If it does as you expect. Keep it a while.If it doesn't dump it.
