$BTC What is the most important principle for trading?

Everyone can rattle off a bunch of correct answers: cut losses, trade with small position sizing, follow the trend, be patient, don’t hold onto a losing position, don’t be greedy, don’t trade too frequently……
Every single one is a standard answer.

But even if they’re all right, you’ll still lose if you do them—because these are outcomes, not the process.

Loss cutting is correct, but how do you cut, where do you place the stop, and what do you do if you’re wrong? Small position sizing is correct, but how small is “small,” how much risk is acceptable, when can you increase size, and do you add during big market moves? Following the trend is correct, but how do you judge the trend, when do you take profit, and if you exit and it keeps rising, do you chase?
—These are the paths you need to walk.

From “understanding it” to “truly doing it,” there’s an entire road in between—and this road is the dividing line between making money and losing money!
