The two most common "traps" in supporting and resistance trading are: first, fake breakouts (stop hunting), and second, drawing lines too rigidly. The core principles to avoid these pitfalls are as follows:

Treat it as a "zone" rather than a "line": The market is made up of countless traders, and quotes have deviations. Viewing support/resistance as a price range (e.g., a 10-20 point buffer) rather than an absolute line can prevent missed opportunities and misjudgments.
Be wary of "liquidity hunting": Major players often use false breakouts to trigger retail traders' stop-loss orders just below support or above resistance (to gather liquidity), then reverse. Stop-losses should be placed outside the zone with appropriate buffer distance (e.g., 1x ATR), not too tight.
Wait for confirmation, avoid chasing prices: True breakouts are usually accompanied by increased volume and a close above/below the level. Wait for a pullback confirmation after the breakout (such as retesting the original resistance as support) before entering, which is safer than chasing the breakout directly.
Observe larger timeframes: Small timeframes (like 1-minute, 5-minute) are noisy, and support/resistance levels are more likely to fail. First identify the major trend on 4-hour or daily charts, and only trade retracements within the larger trend, increasing the win rate.
Pay attention to "consumption" and risk-reward ratio: Multiple tests of the same level in a short period weaken it (more prone to break). If the stop-loss is far from support but resistance above is close (poor risk-reward), it’s better to skip the trade.
