Recently, I was thinking about something every trader should know better – what is an ATH and why do so many people make bad decisions when it appears. Many of us know that buying low and selling high is the way to profits, but when a cryptocurrency reaches its all-time high, everything changes.

What exactly is an ATH? It stands for All Time High – the highest price that a given asset has ever reached. It sounds simple, but the psychology behind this term is complicated. When you see an ATH on a chart, it’s not just a number – it’s a moment full of emotions, FOMO, and often irrational decisions.

What has always struck me in such moments is the fact that investors rely on intuition instead of technical analysis. That’s a recipe for disaster. Experienced traders know that before the market reaches an ATH, it must go through a correction and gain momentum. It’s like a spring – it needs to be compressed to jump higher.

When an ATH appears, it’s worth applying specific tools. Fibonacci is my favorite – these levels 23.6%, 38.2%, 61.8% are no coincidence; they are points where the market often tests support and resistance. Moving averages (MA) are also useful – if the price is below the MA line, the trend is downward; above it – upward.

But what is an ATH in trading practice? It’s a moment when you need to be especially cautious. The price breakout process occurs in three phases: action, when the price breaks resistance; reaction, when momentum weakens; and finally, the resolution, which confirms or negates the trend. If you don’t understand these stages, it’s easy to lose money.

It’s also important to identify new resistance levels after a breakout – Fibonacci extensions such as 1.270, 1.618, or 2.618 are critical points to watch. Always set a stop-loss and determine how much profit you want to take before entering a position.

Once you’re in an ATH position, you need to make a decision: sell everything, part of it, or nothing? If you believe in the long-term value, you can hold. If you want to secure profits, sell part. If Fibonacci extensions align with the ATH price, it’s a signal that the trend may soon end – then selling the entire position makes sense.

What is an ATH ultimately? It’s a test of your skills, discipline, and emotional stability. Every trader should know how to behave in such moments. Share your experiences – how do you handle ATH situations?
