I used to think that ATH was just a number on the chart. But the more I trade, the more I see that it’s much more—it's the moment when the market reaches its peak, and emotions hit their climax.

ATH, that is, All Time High, is the highest price level that a cryptocurrency has ever reached. It sounds simple, but the consequences of this moment for your portfolio can be serious. We all know the theory: buy low, sell high. The problem starts when the price actually reaches what is an ATH—then most investors lose their minds.

When an ATH appears, it usually means the market has absorbed the available supply and the bulls are in control. But the problem begins here. Many traders rely on intuition instead of real technical analysis. Decisions become irrational, and actions impulsive.

What should you do when you see an ATH? First, measure the price momentum. Imagine the market as a spring—before it can reach new highs, it has to first compress. If the price rises without a correction, that’s a warning sign.

Fibonacciego is a tool that actually works. Indicators like 23.6%, 38.2%, 50%, 61.8%, 78.6% aren’t random—that’s where the market tests its strength. The moving average (MA) shows the trend: if the price is below the line, you’re in a downtrend. If above, it’s an uptrend.

But here’s the catch. When an ATH is reached, it doesn’t mean the move is over. Sometimes the market tests this level for weeks or months. It’s a period when inexperienced investors lose money.

A price breakthrough goes through three phases. First comes “action”—the price breaks through resistance and attracts huge volume. Then “reaction”—momentum weakens, and buyers lose strength. Finally “resolution”—it’s decided whether the trend will hold or reverse.

I definitely pay attention to the price structure right below the breakout. Rounded or square bottoms are confirmation. Then I use Fibonacciego from the lowest point to the breakout to find new resistance levels: 1.270, 1.618, 2.000, 2.618. These are levels worth watching.

Set a profit-protection level before you even enter a position. Know how much you want to make and where you’ll exit. Increase your position only when the risk-to-reward ratio is favorable and the price is at MA support.

Now that you have a position at the ATH, what’s next? It depends on your goals. If you’re a long-term investor and you believe in the project, you can hold everything. But it should be a conscious decision, not an emotion.

Most traders choose the middle option—selling part of their position. Fibonacciego extensions come in handy again here. If Fibonacciego extensions line up with the ATH, that’s a signal that the trend may soon be over. In that case, selling the entire position might be reasonable.

ATH in cryptocurrencies isn’t an enemy—it’s an opportunity to learn. Every time it appears, you have a chance to practice and improve your skills. Have you already had experience trading at an ATH? What happened then? Share your stories—we learn best together.
