What is support and resistance?
什么是支撐位和阻力位？

Support and resistance levels are horizontal price levels that typically connect price bar highs to other price bar highs or lows to lows, forming horizontal levels on a price chart.
支撐位和阻力位是水平價(jià)格水平，通常將價(jià)格條高點(diǎn)與其他價(jià)格條高點(diǎn)或低點(diǎn)與低點(diǎn)連接起來，在價(jià)格圖表上形成水平水平。

A support or resistance level is formed when a market’s?price action?reverses and changes direction, leaving behind a peak or trough (swing point) in the market. Support and resistance levels can carve out trading ranges like we see in the chart below and they also can be seen in trending markets as a market retraces and leaves behind swing points.
當(dāng)市場的價(jià)格行為反轉(zhuǎn)并改變方向，在市場上留下峰值或低谷（波動(dòng)點(diǎn)）時(shí)，就會(huì)形成支撐位或阻力位?。支撐位和阻力位可以劃定交易區(qū)間，如下圖所示，它們也可以在趨勢市場中看到，因?yàn)槭袌龌爻凡⒘粝聰[動(dòng)點(diǎn)。

Price will often respect these support and resistance levels, in other words, they tend to contain price movement, until of course price breaks through them.
價(jià)格通常會(huì)尊重這些支撐位和阻力位，換句話說，它們往往會(huì)遏制價(jià)格波動(dòng)，直到價(jià)格當(dāng)然突破它們。

In the chart below, we see an example of support and resistance levels containing price within a trading range. A trading range is simply an area of price contained between parallel support and resistance levels like we see below (price oscillates between the support and resistance levels in a trading range).
在下圖中，我們看到一個(gè)支撐位和阻力位的示例，其中包含交易區(qū)間內(nèi)的價(jià)格。交易區(qū)間只是包含在平行支撐位和阻力位之間的一個(gè)價(jià)格區(qū)域，如下所示（價(jià)格在交易區(qū)間內(nèi)的支撐位和阻力位之間波動(dòng)）。

Note that in the chart below, price eventually broke up and out of the trading range, moving above the resistance level, then when it came back down and tested the old resistance level, it then held price and acted as support…
請注意，在下圖中，價(jià)格最終跌破并走出交易區(qū)間，移動(dòng)到阻力位上方，然后當(dāng)它回落并測試舊的阻力位時(shí)，它隨后守住價(jià)格并充當(dāng)支撐位……

The other primary way support and resistance levels are created in a market, is from swing points in a trend.
在市場上創(chuàng)建支撐位和阻力位的另一種主要方式是從趨勢中的擺動(dòng)點(diǎn)開始。

As a market trends, it retraces back on the trend and this retracement leaves a ‘swing point’ in the market, which in an uptrend looks like a peak and a downtrend looks like a trough.
隨著市場趨勢，它會(huì)沿著趨勢回撤，這種回撤在市場上留下一個(gè)“擺動(dòng)點(diǎn)”，在上升趨勢中看起來像一個(gè)峰值，而下降趨勢看起來像一個(gè)低谷。

In an uptrend, the old peaks will tend to act as support after price breaks up past them and then retraces back down to test them. In a downtrend, the opposite is true; the old troughs will tend to act as resistance after price breaks down through them and then retraces back up to test them.
在上升趨勢中，舊峰值在價(jià)格突破后往往會(huì)充當(dāng)支撐，然后回撤以測試它們。在下降趨勢中，情況恰恰相反;舊低谷在價(jià)格跌破后往往會(huì)充當(dāng)阻力位，然后回撤以測試它們。

Here’s an example of a market testing previous swing points (support) in a downtrend, note that as the market comes back to test the old support, the level then behaves as ‘new’ resistance and will very often hold price. It’s wise to look for an entry point into a trend as it comes back and tests these previous swing points (see pin bar sell signal in chart below), because it’s at these levels that the trend is most likely to resume, creating a low-risk / high-reward potential:
這是一個(gè)市場在下降趨勢中測試先前擺動(dòng)點(diǎn)（支撐位）的示例，請注意，當(dāng)市場回來測試舊支撐位時(shí)，該水平表現(xiàn)為“新”阻力位，并且通常會(huì)保持價(jià)格。明智的做法是在趨勢回歸時(shí)尋找進(jìn)入趨勢的切入點(diǎn)并測試之前的擺動(dòng)點(diǎn)（參見下圖中的柱線賣出信號），因?yàn)檎窃谶@些水平上，趨勢最有可能恢復(fù)，從而產(chǎn)生低風(fēng)險(xiǎn)/高回報(bào)的潛力：

How to trade price action signals from support and resistance levels
如何從支撐位和阻力位交易價(jià)格行動(dòng)信號

Support and resistance levels are a price action trader’s ‘best friend’. When a price action entry signal forms at a?key level of support or resistance, it can be a high-probability entry scenario. The key level gives you a ‘barrier’ to place your stop loss beyond and since it has a strong chance of being a turning point in the market, there’s usually a good?risk reward ratio?formed at key levels of support and resistance in a market.
支撐位和阻力位是價(jià)格行為交易者的“最好的朋友”。當(dāng)價(jià)格行為入場信號在支撐位或阻力位的關(guān)鍵水平形成時(shí)，這可能是一個(gè)高概率的入場場景。關(guān)鍵水平為您提供了一個(gè)“障礙”，可以設(shè)置您的止損，并且由于它很有可能成為市場的轉(zhuǎn)折點(diǎn)，因此通常在市場的支撐和阻力關(guān)鍵水平上形成良好的風(fēng)險(xiǎn)回報(bào)率。

The price action entry signal, such as a?pin bar signal?or other, provides us with some ‘confirmation’ that price may indeed move away from the key level of support or resistance.
價(jià)格行為入場信號，例如針桿信號或其他信號，為我們提供了一些“確認(rèn)”，即價(jià)格確實(shí)可能遠(yuǎn)離關(guān)鍵支撐位或阻力位。

In the example chart below, we see a key level of resistance and a bearish?fakey strategy?that formed at it. Since this fakey showed such aggressive reversal and a false-break of the key resistance, there was a high-probability that price would continue lower following the signal…
在下面的示例圖表中，我們看到了一個(gè)關(guān)鍵的阻力位和一個(gè)在其上形成的看跌?fakey 策略。由于這個(gè)騙局顯示了如此激進(jìn)的反轉(zhuǎn)和關(guān)鍵阻力位的假突破，因此價(jià)格很有可能在信號發(fā)出后繼續(xù)走低……

The next example chart shows us how to trade price action from a support level in an uptrend. Note that once we got a clear pin bar buy signal, actually two pin bar signals in this case, the uptrend was ready to resume and pushed significantly higher from the key support level.
下一個(gè)示例圖表向我們展示了如何在上升趨勢中從支撐位交易價(jià)格走勢。請注意，一旦我們獲得明確的 pin bar 買入信號，在本例中實(shí)際上是兩個(gè) pin bar 信號，上升趨勢就準(zhǔn)備好恢復(fù)并從關(guān)鍵支撐位顯著推高。

The next chart example show us how sometimes in trending markets a previous swing level will act as a new support or resistance level and provide a good level to focus our attention on for price action entry signals.
下一個(gè)圖表示例向我們展示了在趨勢市場中，前一個(gè)擺動(dòng)水平有時(shí)如何充當(dāng)新的支撐位或阻力位，并為我們將注意力集中在價(jià)格行為入場信號上的良好水平。

In this case, the trend was up and a previous swing high in the uptrend eventually ‘flipped’ into a support level after price broke up above it. We can see that when price came back to retest that level the second time, it formed a nice pin bar entry signal to buy the market and re-enter the uptrend from a?confluent level?in the market.
在這種情況下，趨勢是上升的，并且在價(jià)格跌破后，上升趨勢中的先前擺動(dòng)高點(diǎn)最終“翻轉(zhuǎn)”為支撐位。我們可以看到，當(dāng)價(jià)格第二次返回重新測試該水平時(shí)，它形成了一個(gè)很好的 pin bar 入場信號，買入市場并從市場的匯合水平重新進(jìn)入上升趨勢。

Finally, the last chart we are looking at is an interesting one. Note the swing low that occurred in the down trend on the left side of the chart. You can see how this level stayed relevant months later, even after the trend changed from down to up. It first acted as a resistance level after price broke down through it, but once that resistance was broken, we had an uptrend form and then after that, that same level acted as support, and that’s where we see the?fakey pin bar combo signal?in the chart below:
最后，我們正在查看的最后一張圖表是一個(gè)有趣的圖表。請注意圖表左側(cè)下降趨勢中出現(xiàn)的擺動(dòng)低點(diǎn)。您可以看到該水平在幾個(gè)月后如何保持相關(guān)性，即使在趨勢從下降變?yōu)樯仙笠彩侨绱?。在價(jià)格跌破后，它首先充當(dāng)阻力位，但一旦突破阻力位，我們就會(huì)形成上升趨勢，然后，同一水平充當(dāng)支撐位，這就是我們在下圖中看到?fakey pin bar 組合信號的地方：

Tips on Support and Resistance
關(guān)于支撐位和阻力位的提示

• Don’t get too carried away with trying to draw every little level on your charts. Aim to find the key daily chart levels, like we showed in the examples above, as these are the most important ones.
  不要太得意忘形地嘗試在圖表上繪制每一個(gè)小級別。旨在找到關(guān)鍵的日線圖水平，就像我們在上面的例子中展示的那樣，因?yàn)檫@些是最重要的水平。
• The horizontal lines of support or resistance that you draw won’t always touch the ‘exact’ high or low of the bars it connects. Sometimes, it’s OK if the line connects bars slightly down from the high or up from the low. The important thing to realize is that this is not an exact science, instead it is both a skill and an art that you’ll improve at through training, experience and time.
  您繪制的支撐或阻力水平線并不總是觸及它所連接的柱線的“確切”高點(diǎn)或低點(diǎn)。有時(shí)，如果這條線連接的條形從高點(diǎn)略微向下或從低點(diǎn)略微向上，那也是可以的。重要的是要意識(shí)到，這不是一門精確的科學(xué)，它既是一種技能，也是一門藝術(shù)，您將通過培訓(xùn)、經(jīng)驗(yàn)和時(shí)間來提高。
• When in doubt about whether to take a particular price action entry signal or not, ask yourself if it’s at a key level of support or resistance. If it’s not at a key level of support or resistance, it might be better to pass on the signal.
  當(dāng)不確定是否采取特定的價(jià)格行為入場信號時(shí)，問問自己它是否處于關(guān)鍵支撐位或阻力位。如果它不在關(guān)鍵支撐位或阻力位，最好傳遞信號。
• A?price trading strategy, such as a pin bar, fakey, or?inside bar strategy?has a significantly better chance of working out if it forms from a confluent level of support or resistance in a market.
  價(jià)格交易策略，例如 pin bar、fakey 或?inside bar 策略，如果它從市場的支撐或阻力匯合水平形成，則成功的機(jī)會(huì)要大得多。
