Your Entry Price Is the Worst Advisor You Have

You bought BTC at $48,000. It's now $41,000. A friend asks whether you'd buy it today, fresh, with no position — and you say no. The trend's broken, momentum's gone, you'd wait for a better setup. Then they point out you already own it, at that exact price, and you won't sell.

That's anchoring. It might be the most expensive thing your brain does to you in a trade.

In 1974, Amos Tversky and Daniel Kahneman ran an experiment that should bother every trader. They rigged a wheel of fortune to land only on 10 or 65, had people spin it, then asked what percentage of UN member states were African nations. Those who landed on 10 guessed 25%; those who landed on 65 guessed 45%. A random number they'd just watched get generated moved their answer by twenty points.

Your entry price is that random number. The market doesn't know you paid $48,000, and it doesn't care. Your cost basis is information about your past, not about where the asset goes next. But it sits in your head as the "real" price — the one every move gets measured against.

So when price drops, you stop asking the useful question. Instead of "is this still a position I'd want?" you ask "when does it get back to what I paid?" Those aren't the same question — one is about the market, the other is about your ego.

Here's what most traders miss: anchoring doesn't feel like a bias. It feels like patience. It feels like conviction.

You tell yourself you're holding through the noise, staying disciplined. But discipline means following a rule you set. Refusing to sell because you're underwater is the opposite — you're letting a number that has nothing to do with current conditions make the call for you.

You sell winners fast because the gain feels real and good. You hold losers because selling means admitting the entry was wrong.

That last move is the cruelest one. Price drops, your anchor stays fixed, so you "average down" to lower your cost basis. Now you've doubled your exposure to a position the market is actively telling you is wrong — all to defend a number that exists only on your statement.

The fix isn't willpower. You can't out-discipline a bias you can't even feel working. The fix is to make the decision before you hold anything, while you're still not anchored to a price.

Before you enter, write down the level where you're wrong. Not "I'll see how it feels" — an actual number. When price reaches it, you're out, no matter what you paid. The whole trick is making that call while your head is clear, before the sting of being down real money ever shows up.

I stopped trusting myself to do this by hand years ago. Every time I'm in a position, the anchor creeps back in; it's wired too deep to argue with mid-trade. A system doesn't have a cost basis. It doesn't know what I paid and it doesn't care, which is exactly why it can close a loser without flinching.

If you've ever held a bag back toward break-even and called it patience, that's worth sitting with. Getting your entry price out of the decision is most of the battle.
