An RSI of 70 indicates that the asset is overbought, suggesting it might be due for a price pullback. fxcm canada review While it’s not necessarily “bad,” it signals caution as the price could reverse soon. It suggests the asset is in an upward trend but isn’t overbought, so it may have room to continue rising. If the RSI is 20, it indicates that the asset is potentially oversold, suggesting that it might be undervalued and could be due for a price correction or reversal to the upside. For example, during an uptrend, the RSI is likely to stay above 30 and should frequently hit 70.
An RSI in the higher range — particularly above 70 — shows that a stock has had strong upward price momentum. However, that momentum can often indicate that the stock is overbought. Investors may be more likely to sell to capitalize on the buying momentum and take some of their profits. Relative Strength Index (RSI) is an indicator of price momentum, and its values range from 0 to 100. broker finexo The number helps gauge whether the price of a stock is on the rise or on the decline.
- If a 10 day lookback period consistently appears to be better than the default 14-day, there is no need to stick with the latter.
- Then, to filter out some bad trades, we also have a filter applied to the strategy.
- Wilder thought that “failure swings” above 50 and below 50 on the RSI are strong indications of market reversals.[6] For example, assume the RSI hits 76, pulls back to 72, then rises to 77.
- It could be that we just need to think a little differently, and turn the logic upside down.
- The most common settings for the RSI indicator is a 14-days lookback period with the oversold threshold set at 30 and the overbought threshold set at 70.
- An RSI reading of 30 or below indicates an oversold or undervalued condition.
Taking mean reversion trades many times is like trying to catch a falling knife. Conversely, if the downtrend cannot reach 30 or below and then rallies above 70, that downtrend has weakened and could be reversing to the upside. Remember, both trend lines and moving averages are helpful technical tools to include when using the RSI in this way.
Wilder posited[1] that when price moves up very rapidly, at some point it is considered overbought. Likewise, when price falls very rapidly, at some point it is considered oversold. The RSI is most typically used on a 14-day timeframe, measured on a scale from 0 to 100, with high and low levels marked at 70 and 30, respectively. Short or longer timeframes are used for alternately shorter or longer outlooks. High and low levels—80 and 20, or 90 and 10—occur less frequently but indicate stronger momentum.
RSI vs. MACD
While much has changed in investing due to technological disruption, RSI has been around since well before anyone could trade on their smartphones — or since anyone even had a smartphone. Welles Wilder, Jr.’s book, “New Concepts in Technical Trading Systems,” with the aim to help understand whether a stock was overbought or oversold. It is important to note that RSI is part of what is known as technical analysis.
RSI Breakouts
Using the RSI in this way is very similar to drawing trend lines on a price chart. It’s quite the same, except that RSI Cutlers version uses a simple moving average rather than an exponential moving average. To understand the difference better, let’s just remind us of the default calculation. As we already mentioned, the RSI often works great for detecting market strength that’s worth acting on. That’s also in line with the main objective of this trading strategy, that attempts to identify those times when the market is strong enough to continue in the direction of the momentum.
Importance of Divergence and Convergence in Signal Validation
When we used the highs and lows of the RSI to set the breakout levels, we effectively made use of support and resistance levels. By noting when the market broke through a resistance level, we ensured that there was no resistance in the way for the market to get stuck at. Upon a visit to some of the greater trading sites online, you will find a lot of “trading strategies” that actually don’t work at all. In most cases, the author has just put together some nice looking indicators or logics, and presents them as working trading strategies. We know from experience, after having backtested many of these strategies, that close to every strategy of this kind is garbage. An RSI of 40 indicates slightly bearish momentum, suggesting the asset is closer to being oversold than overbought.

The RSI is displayed as an oscillator (a line graph) on a scale of zero to 100. Welles Wilder Jr. and introduced in his seminal 1978 book, New Concepts in Technical Trading Systems.
In addition, bearish signals during downward trends are less likely to provoke false alarms. As the relative strength index is mainly used to determine whether a security is overbought or oversold, a high RSI reading can mean that a security is overbought and the price may drop. As with most trading techniques, this signal will be most reliable when it conforms to the prevailing long-term trend. Bearish signals during downward trends are less likely to generate false alarms.
The MACD is calculated by subtracting the 26-period exponential moving average (EMA) from the 12-period EMA. As we’ve already mentioned, RSI is a momentum oscillator that’s used to measure the speed and change of price movements. It fluctuates between 0 and 100, and by reading its value you can get a sense of whether the market is overbought or oversold.
However, you should keep in mind that most traders are unsuccessful, with the corollary that common trading strategies also tend to not work so well. The most common way of doing this is to require the RSI to cross below or above a threshold. Usually, that’s 70 for the overbought threshold, and 30 for the oversold threshold. In the image below you can see what it looks like when the RSI crosses the overbought and oversold thresholds.
Some traders consider it a buy signal if a security’s RSI reading moves below 30. This is based on the idea that the security has been oversold and is therefore poised for a rebound. However, the reliability of this signal will depend in part on the overall context. If the security is caught in a significant downtrend, then it might continue trading at an oversold level for quite some time. Traders in that situation might delay buying until they see other technical indicators confirm their buy signal.
