KDJ, A Short-Term Trading Tool
Here are the basics on KDJ, plus a few more helpful tips on how to use KDJ properly.
KDJ can be used to find potential overbought and oversold areas and potential reversals in price action. The basics of KDJ that you need to know are its overbought and oversold areas. A KDJ reading of 80 or above is overbought, and a reading of 20 or under is an oversold reading. Typically, an overbought reading is bearish, and an oversold reading is bullish.

More basic aspects of KDJ are its bullish and bearish crosses. A bullish cross is indicative of short-term upside. A bearish cross shows a short-term downside. These crosses are not 100% dependable all of the time because KDJ is a lagging indicator. But sometimes It can work beautifully with a high success rate.
Here is an example with TSM's chart with daily candles. If you took a long position at almost every bullish cross, then you would have been profitable. Conversely, if you took a short position at every bearish cross, then you would have been profitable. Of course there are always false signals and things dont always work out so perfectly like you see here.
Here is a helpful tip about KDJ during a rally. KDJ value will typically stay above 50 in a sustained rally. You will see bearish crosses in overbought territory where it would have been a bad idea to take profit or go short like KDJ would typically call for. Conversly, in a sharp downtrend KDJ value stays below 50.
Here you can see a chart with the stock $特斯拉 (TSLA.US)$ , which was in a strong rally. The KDJ value during this time stayed above 50 furing the rally. Seemingly bouncing off of the 50 value as if it was a support level.
As seen above and below, bullish and bearish crosses are not always correct. Sometimes you will break even or take a loss off of KDJ trading. Other times you will see false crosses that indicate false reversals in price action.
How would you know if it is a false bullish or bearish cross before its too late? You can use the KDJ 50 value as a sort of confirmation to provide you with more confidence in your trade. Usually you want to look for bullish crosses in oversold territory, and bearish crosses in overbought territory.
When you get a bullish crossover in oversold territory then you can watch for KDJ to cross above the 50 value for confirmation. In a bearish crossover KDJ can confirm the downtrend when it crosses below the 50 value. Here is an example below with $蘋果 (AAPL.US)$
To be more successful with KDJ you could pair it with other indicators such as MACD and RSI to get more confirmation in your trading. I like to think of KDJ as a faster paced indicator rather than a short term indicator as it works in any time frame but at a faster pace as compared to RSI and MACD. So typically you would get a reversal reading on KDJ before other indicators.
For example with $Meta Platforms (FB.US)$ on the weekly candles you can see how KDJ gives a bullish or bearish signals before RSI and then MACD typically follows last. Occasionally, you can use RSI and MACD’s reversal signals as confirmation of KDJ’s reversal reading.
Always remember that KDJ is a lagging indicator as it is dependent on price action before it is calculated. So it does not predict the future. It only indicates past price action. So don't use it as a crystal ball. And in a bull market you should mostly search for bullish signals. And in a bear market you should look for bearish signals to be more successful. I hope this provides a little more insight on how to use KDJ properly.

solo invest : 我從來沒有真正理解過KDJ背後的含義和如何使用它，每個人都把它弄得如此複雜和難以理解，但我可以清楚地理解你在這裏解釋它的方式，謝謝，我很欣賞。
SpyderCall 樓主 solo invest : 見鬼，沒問題。我一直把KDJ放在我的屏幕上。它特別適合於日內交易和短期波動交易。
solo invest : 我喜歡這個例子，比如$Taiwan Semiconductor (TSM.US)$。KDJ在這些每日蠟燭上的交易將會非常有利可圖
feng yongdie SpyderCall 樓主 : 請問一下，日內看5分鐘，還是看10分鐘好？
SpyderCall 樓主 : 在5支和10支蠟燭上交易KDJ將是非常快的交易節奏。這些時間框架肯定只適用於日間交易。但最重要的是。有一件事要知道，當交易在非常小的時間框架，KDJ必須看起來很好的每日蠟燭，然後你應該考慮日內交易或擺動交易任何東西在5分鐘或10分鐘的時間框架
icezzz : 謝謝你的分享，非常清楚

Ben Albright : 謝謝
Nblaze : 在這個指標上，你認為什麼時間段最適合做黃牛和日內交易。？太棒了
順便説一句，這是如何工作的細目。
SpyderCall 樓主 : 謝謝。我總是先看看日常的蠟燭。如果你是短線交易，如日間交易和搖擺交易，每日蠟燭顯示整體趨勢。你可以預測哪裏可能會出現額外的波動性或成交量。通常，這些感興趣的區域將在日均蠟燭的主要支撐位或阻力位附近。然後，我通常會等待日線蠟燭接近可能發生突破或逆轉的支撐位或阻力位。之後，我會放大到4小時蠟燭或1小時蠟燭，以跟蹤這些短期趨勢，並找到一個擺動交易的入口。我總是注意一分鐘的蠟燭，看看成交量是否有其他投資者在做出和我一樣的決定。但對於非常短的交易日交易，我仍然關注1小時和4小時的蠟燭和指標。但我會把3分鐘、5分鐘或15分鐘的蠟燭換成非常快的進場和退場，我仍然會一直看着一分鐘的蠟燭音量
