Lines
Horizontal lines and rays (support and resistance)
A level line marking a price where the market has turned before and may react again.
Идея простыми словами
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.
Как считается
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 itКак использовать
- Mark recent highs and lows, round numbers and earlier breakout levels.
- Place alerts on the line: select it and press "Alert at this price".
Выводы
- 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.
Пример
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.
Цены в примерах приведены для иллюстрации.
На что обратить внимание
- Levels are zones, not exact prices: allow a little room.
Немного истории
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).
