RSI指標(Relative Strength Index)是什麼？ RSI指標計算公式？ RSI指標運用：​趨勢、背離、死亡交叉、黃金交叉、鈍化問題 ...Mr.Market市場先生技術分析中最廣為人知的指標有KD、MACD、RSI指標，其中RSI指標(RelativeStrengthIndex,RSI)又稱為相對強弱指標，這個指標主要是透過市場近期漲跌的變化量，衡量近期一段時間內的買盤與賣盤，雙方的相對力量強弱程度。

這篇文章市場先生介紹RSI指標，共分為以下幾個部分：RSI指標(RelativeStrengthIndex)是什麼？RSI指標計算公式？RSI指標運用：趨勢、背離、死亡交叉、黃金交叉、鈍化問題台股RSI指標查詢方式美股RSI指標查詢方式市場先生對技術分析的小提示：我認為所有技術分析方法，真正功能都是在幫我們「簡化過去資訊」，而不是直接能用在未來選股與時機預測。

透過簡化後的資訊判讀，用來當成判斷未來狀況的分析依據，提高可信度，在開始了解之前，務必要記得，並沒有什麼技術指標是能百分之百預測未來的。

何謂RSI相對強弱指標？RSI指標(英文:RelativeStrengthIndex,RSI)又稱為相對強弱指標，主要是用來評估股市中「買賣盤雙方力道的強弱」，這是一種技術分析的動量指標，衡量近期價格變化的幅度，來評估股價超買或超賣情況。

這個技術指標是由WellsWilder於1978年發明，主要用來計算價格的漲跌，將股價易變動的幾個因素考量進來(上漲和下跌的天數、上漲和下跌的幅度)，因此許多投資人會用這個技術分析指標評估進退場的時機點。

RSI指標的買賣雙方強弱有什麼影響？當賣盤力道較強勢，預期股價就有向下會跌的比較多；若買盤力道較強勢，預期股價上漲相對比較多。

但如果只看目前相較過去一段時間的漲跌幅度，就會忽略掉過程的變化。

例如：同樣在10天上漲2%，不同的時間點，過程的走勢可以是完全不一樣的(例如：走勢可以是緩緩上漲，或是先大跌再大漲再下跌等等)，透過RSI指標，不只是看出漲跌，還可以反應出不同過程中買賣雙方產生的力量。

或者只從價格上來看，也可以說是：上漲下跌走勢的趨勢乾淨程度。

多方或空方力量越強，走勢就越乾淨、指標數值也越極端。

KD指標、RSI指標有什麼不同呢？這兩個指標都是技術分析中的動量分析方法，主要差異為：KD指標(隨機指標)：KD指標呈現「最新股價的相對高低位置」，估股價目前處於相對高點或低點。

RSI指標(相對強弱指標)：RSI指標呈現「一段時間內股價買盤與賣盤力量強弱比例」，評估力量是相對平衡還是懸殊。

市場先生建議看公式、動手算算看，比較容易理解它的意思。

RSI指標計算公式？RSI(相對強弱指標)=n日漲幅平均值÷(n日漲幅平均值+n日跌幅平均值)×100其中，n日漲幅平均值=n日內上漲日總上漲幅度加總÷nn日跌幅平均值=n日內下跌日總下跌幅度加總÷n常用的n是14天，不過通常各軟體都可自行設定天數參數。

RSI(相對強弱指標)是用某段時間的股價平均漲幅(只計算上漲時)、平均跌幅(只計算下跌時)來計算的，可以看出股價某段時間內的價格強勢或弱勢，簡單來說就是用買賣雙方拉抬的力道，運算出雙方均衡點，判斷股價在一段期間內的未來走勢。

舉個計算例子：最近14天中，有10天是上漲，累積漲幅加總是14%，平均漲幅就是14%÷14=1%有4天是下跌，累積跌幅是-7%，平均跌幅就是7%÷14=0.5%RSI=1%/(1%+0.5%)×100=66.7RSI指標(相對強弱指標)的區間為0～100，通常數值會以50作為多空的區隔：RSI值>50：代表買方力道較強勁，平均上漲幅度大於平均跌幅。

RSI值<50：代表賣方力道較強勁，平均下跌幅度大於平均漲幅。

如果最近上漲幅度大、下跌程度小，RSI數字通常就會高於50以上，上漲趨勢越強數字越大。

反之如果最近下跌幅度大，上漲漲幅小，RSI數字通常就會在50以下，下跌趨勢越強數字越小。

如果波動劇烈但累積的漲跌程度相當，也無明確多空，那RSI數字就會在50附近。

下一段會談到RSI的運用判斷方式。

RSI使用上要留意的限制從公式中可以看出來RSI的好處與幾個問題。

RSI的優點，在於可以快速的反應出最近漲跌的強弱程度。

但從RSI計算公式中，市場先生建議要留意一些問題，整理RSI的使用限制如下：1.RSI只是整理出過去一段時間的狀況，意思是它並
