How to Use RSI (Relative Strength Index)

Relative Strength Index, or RSI, is similar to the stochastic in that it identifies overbought and oversold conditions in the market. It is also scaled from 0 to 100. Typically, readings below 30 indicate oversold, while readings over 70 indicate overbought.

How to Trade Using RSI

RSI can be used just like the stochastic. We can use it to pick potential tops and bottoms depending on whether the market is overbought or oversold.

Below is a 4-hour chart of EUR/USD.

Using RSI to pick tops and bottoms=

EUR/USD had been dropping the week, falling about 400 pips over the course of two weeks.

On June 7, it was already trading below the 1.2000 handle. However, RSI dropped below 30, signalling that there might be no more sellers left in the market and that the move could be over. Price then reversed and headed back up over the next couple of weeks.

Determining the Trend using RSI

RSI is a very popular tool because it can also be used to confirm trend formations. If you think a trend is forming, take a quick look at the RSI and look at whether it is above or below 50.

If you are looking at a possible uptrend, then make sure the RSI is above 50. If you are looking at a possible downtrend, then make sure the RSI is below 50.

RSI goes below 50 on a downtrend

In the beginning of the chart above, we can see that a possible downtrend was forming. To avoid fake outs, we can wait for RSI to cross below 50 to confirm our trend. Sure enough, as RSI passes below 50, it is a good confirmation that a downtrend has actually formed.


       相对强度指标,简称RSI(Relative Strength Index),与随机振荡指标类似,它同样是用来确认市场,处于 超买 还是 超卖。它的刻度也是从0到100。通常情况下,低于30就是超卖,而超过70就是超买。


       RSI指标可以像随机振荡指标一样使用。我们根据市场是 超买 还是超卖,来寻找潜在的高点和低点。

       以下是 欧元/美元 的4小时图表。

       欧元/美元 已经下跌了整个星期,跌幅在两个星期内已超过约400点。

       在6月7日,价格已经在1.2000形成杯柄形态。然而,RSI 已经跌至30以下,这表明 市场可能没有剩下 太多的卖家,而且趋势可能结束了。价格之后果然反转,调头连续上升了几个星期。


       RSI指标是一个非常受欢迎的工具,因为它也可以用来确认趋势的形成。如果你认为一个趋势正在形成,只需要快速的浏览一下RSI指标,看看它是否高于 或低于50。


       在上面图表的初期,我们可以看到一个潜在的下跌趋势正在形成。为了避免假讯号,我们可以等待 RSI指标向下穿过50后 才确认我们的趋势。果然如此,当RSI 下穿50 后,这是对下跌趋势的形成,最好的确认方法。
