The flashing red numbers on the screen instantly quicken my pulse, but I remain calm — my trading system has already given me the answer. There is opportunity before me, not a trap.

In late December, when Bitcoin attempted for the third time to break through the $86,000 barrier, I made a decision. Go all-in long. To be honest, my students were all holding their breath for me. But this is not a reckless gamble; it’s a clear signal from my trading system.

Today I want to talk about those core technical indicators that saved my life at critical moments. In a market filled with emotion and panic, only data never lies.

**DMI/ADX: The Truth Behind the Trend**

While everyone is still debating "Is it a rebound or a continued decline," my DMI/ADX has already provided a definitive answer.

On December 23rd, I noticed the +DI line starting to approach the -DI line from below, and the ADX (Average Directional Index) dropped below 20 — indicating that the previous decline was losing momentum. This is an early warning sign of a trend reversal.

Three days later, on the 26th, the turning point appeared. The +DI crossed above the -DI, forming a "golden cross," while the ADX started turning upward from a low level. The new trend was confirmed. Why is this signal so reliable? Because it directly reflects the real-time change in the strength of bulls and bears.

A tip: Using DMI crossovers alone can be misleading; they must be combined with ADX. Only when ADX breaks above 25 does it indicate that the trend has genuine explosive power to sustain.

**Bollinger Bands: The Container of Price Fluctuations**

Bollinger Bands are not just an indicator; they are actually a "container" for price movements. When Bitcoin repeatedly tests around $86,000, the middle band (20-day moving average) acts like gravity, repeatedly pulling the price back.

I observed that the lower band kept rising, which usually means the bottom is being gradually lifted — seller strength is waning. When the price approaches the lower band without breaking below, it’s time to consider adding to your position. This time was no exception.

**Why Data Is More Convincing Than "Influencers’ Opinions"**

The market is not short of voices; what’s lacking is rationality. Some shout bearish, others shout bullish, but the trading system does not lie. It only responds to the real reactions of price, volume, and time to tell you what to do next.

That heavy position in December was my trust in data overcoming the fear of uncertainty. And the result? You’ve already seen Bitcoin’s subsequent movement.
