Lines
Horizontal lines and rays (support and resistance)
A level line marking a price where the market has turned before and may react again.
用通俗的话解释
Traders remember prices. A level where buyers stepped in before (support) or sellers appeared (resistance) often matters again, because people who missed it last time place orders there.
计算方法
Click once at the price. A horizontal ray starts at your click and runs to the right.
A single price: support below the market, resistance above it如何使用
- Mark recent highs and lows, round numbers and earlier breakout levels.
- Place alerts on the line: select it and press "Alert at this price".
得出结论
- When resistance breaks, it often becomes support (and vice versa).
- The more often a level was tested, the more attention it gets, but each test can weaken it.
示例
GOLD has turned down three times near 2,400. A horizontal line at 2,400 marks resistance; a daily close at 2,420 is a breakout, and the old ceiling then acts as a floor on the pullback.

注意事项
- Levels are zones, not exact prices: allow a little room.
一点历史
Support and resistance are the foundation of chart reading, described in classic texts such as Edwards and Magee's "Technical Analysis of Stock Trends" (1948).
