Most people fail in trading not because they don't know how to read the market, but because their positions are too heavy, overwhelming their judgment. You clearly know the trend is still there, but you become restless after holding a 10-point loss; you clearly plan to cut losses, yet when the time comes, you still think about holding on a bit longer.
Why? Because you are betting too heavily; you are no longer executing a strategy, but trying to "save yourself."
The traders who can survive long-term are not necessarily smarter than you, but they know what position size allows them to sleep at night. If you can tolerate a 3% fluctuation, don't set a 10% stop loss; if your mindset can only handle small losses, don't go all in.
Trading is not about making a quick profit on one trade; it's about enduring countless times of "being able to afford losses." The more you want to make money quickly, the more the market will teach you a lesson first.
