Oversold, or undervalued, conditions signal that a price increase could be coming. In other words, you should buy a stock when it reaches an RSI of 30 and sell or short when it hits an RSI of 70. The relative strength index is a technical indicator that measures the momentum of a security based on its closing prices. Once calculated, the RSI is displayed as an oscillator, which is a line graph between two extreme values. 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.
Trading indicators have served as useful tools for traders since trading has existed to help them make informed predictions about their positions. The RSI can also be used in combination with these indicators to identify bearish signals when the RSI is above 70 and a bearish crossover is observed in either the MACD or moving averages. Failure swings are a pattern in the RSI itself, independent of price action, that can be used to identify when a reversal is likely to occur. A bullish failure swing occurs when the RSI drops just below 30 briefly and then bounces, before falling back down to hold just above 30. If the RSI bounces again and breaks its prior high, a failure swing is said to have occur and should predict a significant price movement. A bearish failure swing follows the opposite pattern around an RSI of 70, with the RSI bouncing below its previous low indicating a failure swing. As explained in the moving average calculator, the SMA’s purpose will be to show a price trend reversal based on the change of RSI trend.
