The core logic of trading time levels: observe fluctuations on a small chart, determine the situation on a large chart.

Traders who focus on the 30-second chart often fall into the cognitive trap of "noise equals trend"—what you see as an "extreme crash" in your eyes is merely a healthy correction on the 1-hour timeframe; what appears as a "strong surge" on the 1-hour chart is just a ripple of a rebound when viewed on the weekly scale.

The same set of price data presents completely different trading meanings under different time frames: small-scale candlesticks are dominated by short-term capital speculation, filled with irregular noise, which easily induces emotional follow-the-trend operations; while large-scale charts can better highlight market structure logic, allowing one to see the core direction of the trend through short-term fluctuations.

If stop-loss settings, trading rhythm, and mindset control are all skewed by small-level fluctuations, the market will only be a chaotic manifestation of "violent rises and falls"; only by anchoring to a time level that matches one's own trading system can one escape the emotional trap and truly grasp the initiative in trading, seizing certain opportunities amidst fluctuations.
