One common mistake many traders tend to make is focusing on only one indicator. This could give a false signal, causing you to possibly trade against the trade.
On the other hand, using too many indicators could result in conflicting signals, so combining only two indicators that could correlate with each other might be better.
Below are four different indicators that could be used interchangeably.
Relative Strength Index (RSI)
The Relative Strength Index (RSI) is a popular momentum oscillator indicator determining areas where price could be seen as overbought or oversold. It calculates the ratio between a currency pair’s highest and closing price and lowest closing price over a specific period.
The indicator has a solid line moving between 0 and 100. There are two horizontal lines, one at the 70 level and one at the 30 level.
Theoretically, when the line is at or above the 70 level, the price could be seen as overbought, whereas if it is at the 30 level, it could be seen as oversold.
This suggests that the price could soon reverse when trading at or above the 70 level or at or below the 30 level.
Stochastic Oscillator
The Stochastic Oscillator is also a momentum oscillator indicator used to determine areas where the price could be seen as overbought or oversold. It takes the most recent closing price data and compares it to the previous trading range spanning 14 days.
The difference between this indicator and the RSI is the solid moving line. This indicator has two solid moving lines: the first is called the indicator line, generally presented as a solid white line, and the second is the signal line, generally presented as a solid red line.
These two lines also move between a range from 0-100. However, the two horizontal lines are instead situated at the 80 and 20 mark levels.
As theory suggests, when the price moves at or above the 80 level, it could be seen as overbought, whereas if it moves at or below the 20 level, it could be seen as oversold.
You could also use this indicator to look for a potential price reversal towards the downside when the indicator line crosses below the signal line at or above the 80 level; however, if the indicator line crosses above the signal line at or below the 20 level.
Moving Averages
Moving averages are lagging indicators, which means they are used to confirm the trend, not identify it. They take the closing price data of a currency pair over a certain period and simplify the visual data by presenting it as a solid moving line.
So, if we take the 20-day moving average, it uses the closing price of the last 20 days, adds the prices up, and then divides it by 20 to get an average price range. This data is then presented in a single moving line to provide a better overview of the overall trend movement for the last 20 days.
Theoretically, traders could confirm the trend by looking at the moving average in relation to the price. If the moving average is above the price, it suggests the market is in a downtrend. If it is below the price, it indicates the market is in an uptrend.
Traders could also use the moving average crossover strategy to look for potential reversals in the market. This strategy involves having two or three moving averages cross over above or below each other.
In other words, if the 20-day moving average crosses above the 50-day moving average and the 50 crosses above the 100-day moving average, it’s known as the golden cross. It signals a possible change in trend direction towards the upside.
Conversely, when the 20-day moving average crosses below the 50-day moving average and the 50 crosses below the 100-day moving average, this is known as the death cross and signals a possible change in trend direction towards the downside.
Support and resistance
Support and resistance levels show how market supply and demand play out. These levels form over time as the price starts to enter a ranging market, where it repeatedly fails to break previous highs or lows and instead reverses.
Resistance levels form when the price fails to break above previous high points and instead reverses towards the downside. At the same time, support levels form when the price fails to break below previous low points and instead reverses towards the upside.
You could look for opportunities in the market when the price is trading at one of these levels, looking for a potential reversal or a potential breakout of one of these levels. When the price breaks below support and moves back up to test that level, it becomes future resistance.
Whereas, if the price breaks above a resistance level and moves back down to retest that level, it becomes future support.
