No matter how skilled you are technically, if your position gets thrown off, you may be wiped out to zero in an instant.

Many traders, when they’re just starting out, are most obsessed with researching techniques—indicators, patterns, entry and exit points—because it seems like once you find the perfect method, you can keep profiting.
But after you’ve experienced it more, you’ll understand: what truly keeps you alive in this market and helps you go farther was never the technology—it was position sizing.
Many people don’t fail because they get the direction wrong; they get it right, but can’t hold onto their trades—while others get it wrong, but can’t stomach the losses.
Where is the problem?
It’s often because the position is too large.
When the position is heavy, drawdowns become bigger;
when drawdowns are big, your mindset is likely to fall apart;
when your mindset falls apart, any technical system will fail.
So, position management, at the end of the day, is not just about “how much to buy,”
it’s about doing two things:
First, not letting any mistake take away your eligibility to keep trading;
Second, always leaving yourself the opportunity to enter again next time.
A light position isn’t cowardice,
it’s so that when your judgment is wrong, you can still stay clear-headed;
when your capital is in drawdown, you can still adjust calmly;
and when opportunities show up again, you still have ammunition.
Truly mature traders don’t just research how to make more money,
they also understand how to research how to survive first in the face of risk.
By the time you reach the end, you’ll realize:
technology determines how much you can earn in a single round,
position sizing determines how far you can go in this market
