Using a bull market strategy in a bear market is like slow suicide.

In a bull market, opening long positions and holding through dips works—everything can come back, and even adding to your position can earn you more. That experience turns into muscle memory in your head. Then the trend changes, and you keep holding until liquidation.
This isn’t a technical analysis problem—it's that the environment has changed, while your strategy hasn’t. In a bull market, what matters is the trend; in a bear market, what matters is position sizing. When the trend is right, going all-in feels like it’s still not enough. When the trend is wrong by 20%, even half your position feels excessive. But the most deadly part is this— the trend has already changed, and you’re still using last month’s logic to convince yourself that it’s “just a correction.”
Many people lose money not because they got the direction wrong, but because they used the right tools at the wrong time. It’s like wearing summer clothes in winter—your clothes are fine, but the season is wrong.
Rule of thumb: if your position makes you wake up in the middle of the night to check the market, then it’s too large. Reduce it to a level where you can fall asleep peacefully, and only then talk about trading strategies. Being able to sleep is a hundred times more important than being perfectly right about the market.
