Terms that inevitably come up when trading cryptocurrencies include ATH. Short for All Time High, which basically refers to the highest price point in history, and this concept is quite important in the trading world.

Simply put, ATH is the highest price an asset has ever reached in its history. This applies to cryptocurrencies like BTC or any other asset. For example, the current ATH for BTC is around $126,000. Reaching this number means that the market participants collectively judged “this price is worth buying.”

Reaching an ATH is an interesting phase. Usually, buying low and selling high yields profits, but trading near ATH is a different story. Buying at this point can lead to significant unrealized losses during subsequent corrections. Many traders fall into this trap.

When an ATH is formed, bullish traders often exert strong buying pressure. There’s a supply shortage, and selling pressure is relatively weak. That’s why prices keep breaking new highs. However, misjudging this situation can lead to painful losses.

In reality, how you act during an ATH depends on your investment style. Long-term holders who genuinely believe in the asset’s future may choose to hold through ATHs as part of their strategy. But if you see it as a temporary overheating, it’s safer to sell some. Many investors prefer this approach—taking partial profits to secure gains while preparing for further upward movement.

In technical analysis, Fibonacci levels and moving averages (MA) are crucial. Fibonacci levels (23.6%, 38.2%, 50%, 61.8%, 78.6%) serve as support and resistance indicators. Moving averages show the trend direction. If the price drops below the MA, it’s likely entering a downtrend.

When aiming for a breakout near ATH, three stages should be considered. The first stage is “Action,” where the price breaks resistance and trading volume increases. The second stage is “Reaction,” where the upward momentum weakens and a correction occurs. The third stage is “Resolution,” where the trend confirmation is finalized.

After reaching ATH, managing your position size is key. Deciding whether to sell everything or just take profits on part of your holdings can be guided by Fibonacci extension analysis. Comparing the previous bottom that formed the ATH with the current ATH helps predict the next target level.

Pre-setting profit-taking points is essential. Set a target profit rate and establish a rule to sell once it’s reached. When increasing your position, ensure the risk-reward ratio is favorable and that the price is supported by the MA. Emotional decisions should be avoided at all costs.

As cryptocurrency prices approach ATH, many traders tend to rely on intuition. This often leads to irrational buying or selling. Therefore, calm and disciplined technical analysis is necessary. Understanding what ATH truly means and reading market psychology are key to maximizing profits.
