Support and resistance

"Support levels" redirects here. For technical support levels, see Technical support.

In stock market technical analysis, support and resistance are certain predetermined levels of the price of a security at which it is thought that the price will tend to stop and reverse.[1] These levels are denoted by multiple touches of price without a breakthrough of the level.

Support versus resistance

A support level is a level where the price tends to find support as it falls. This means that the price is more likely to "bounce" off this level rather than break through it. However, once the price has breached this level, by an amount exceeding some noise, it is likely to continue falling until meeting another support level.[2]

A resistance level is the opposite of a support level. It is where the price tends to find resistance as it rises. Again, this means that the price is more likely to "bounce" off this level rather than break through it. However, once the price has breached this level, by an amount exceeding some noise, it is likely to continue rising until meeting another resistance level.

Reactive versus proactive support and resistance

Proactive support and resistance methods are "predictive" in that they often outline areas where price has not actually been.[3] They are based upon current price action that, through analysis, has been shown to be predictive of future price action[citation needed]. Proactive support and resistance methods include Measured Moves, Swing Ratio Projection/Confluence (Static (Square of Nine), Dynamic (Fibonacci)), Calculated Pivots, Volatility Based, Trendlines and Moving averages, VWAP, Market Profile (VAH, VAL and POC).[3]

Reactive support and resistance are the opposite: they are formed directly as a result of price action or volume behaviour. They include Volume Profile, Price Swing lows/highs, Initial Balance, Open Gaps, certain Candle Patterns (e.g. Engulfing, Tweezers) and OHLC.[3]

A price histogram is useful in showing at what price a market has spent more relative time. Psychological levels near round numbers often serve as support and resistance.[3]

Identifying support and resistance levels

Support and resistance levels can be identified by trend lines (technical analysis).[4] Some traders believe in using pivot point calculations.[5]

The more often a support/resistance level is "tested" (touched and bounced off by price), the more significance is given to that specific level.[6]

If a price breaks past a support level, that support level often becomes a new resistance level. The opposite is true as well; if price breaks a resistance level, it will often find support at that level in the future.[7]

Psychological Support and Resistance levels form an important part of a trader's technical analysis.[8] As price reaches a value ending in 50 (ex. 1.2050) or 00 (ex. 1.3000), people often see these levels as a strong potential for interruption in the current movement. The price may hit the line and reverse, it could hover around the level as Bulls and Bears fought for supremacy, or it may punch straight through. A trader should always exercise caution when approaching 00 levels in general, and 50 levels if it has previously acted as Support or Resistance.

Using support and resistance levels

This is an example of support switching roles with resistance, and vice versa:

If a stock price is moving between support and resistance levels, then a basic investment strategy commonly used by traders, is to buy a stock at support and sell at resistance, then short at resistance and cover the short at support[9] as per the following example:

지원 또는 저항 수준을 사용하여 투자 입출자 타이밍을 판단할 때는 거래 전략 기간과 일치하는 가격 간격 기간을 기준으로 차트를 선택하는 것이 중요하다. 단기 트레이더는 1분(즉, 1분마다 차트에 보안 가격이 표시됨)과 같은 간격 기간을 기준으로 차트를 사용하는 경향이 있다. 장기 트레이더는 일반적으로 시간별, 일별, 주별 또는 월별 간격 기간을 기준으로 가격 차트를 사용한다. 일반적으로 거래자들은 15분마다 가격이 표시된 1주간의 과거 데이터에 근거한 다음 예와 같이 투자 시기를 최종 결정할 때 단기 간격 차트를 사용한다. 이 사례에서 주가가 하락세에서 벗어나고 있다는 초기 징후는 30.48달러에서 지지세를 형성하기 시작한 뒤 고점, 저점을 형성하기 시작했을 때다. 이것은 부정적인 경향에서 긍정적인 경향으로의 변화를 예고한다.[citation needed]
