Correct Use of Support and Resistance
In an Uptrend: Resistance levels are used to take profits on long positions or spot trading, not to set up short positions; Support levels are used to set up entry points;
In a Downtrend: Resistance levels are used to set up entry points, and support levels are used to take profits on short positions, not to catch the bottom.
Before trading, clarify the overall market situation (monthly, weekly) trend; do not focus on the daily chart's fluctuations below that level.
