Features and Advantages of The RSI Indicator
As any other oscillator, the RSI indicator is not plotted on the price chart, but in a separate window below. This technical instrument consists of a single line and two levels set by default.
Vertical axis range of the indicator is set to 1 to 100 showing extremality of current price against its previous values.
RSI values calculation
RSI = 100 – (100 / (1 + U/D))
U – average number of positive price changes
D – average number of negative price changes
What the formula means, is that if the price grows against previous values, so does indicator reading; otherwise, oscillator’s value goes down.
The RSI line may reach 0 or 100 only during strong, continuous downward or upward trend, respectively.
Usually standard overbought and oversold levels are 70 and 30. If the indicator’s line goes above the 70 level, it signals that market is overbought and the trend may reverse downwards.
If the indicator’s line goes below the level 30, it signifies that market is oversold and the trend may reverse upwards.
The reference level is 50, and it is the median value. If the indicator chart is ranging between the levels 30 and 70, the market is flat or that the current trend is smooth, steady and there is less of a likelihood for reversal in short-term
Sometimes, overbought and oversold levels are set at 80 and 20 instead of 70 and 30. This setting is used during increased market volatility.
Setting and Adjusting RSI Indicator
There are two ways to set up this indicator. The easiest way is to click the tab ‘List of Indicators’ located on the upper panel of the terminal and select ‘Oscillators’ – ‘Relative Strength Index’.
Another option is to choose ‘Insert’ – ‘Indicators’ – ‘Oscillators’ – ‘Relative Strength Index’.
Instrument configuration window will open before the indicator is set in the chart. This window allows you to configure the indicators parameters.
The main parameter is the period; It defines the number of price values taken into consideration at plotting the main indicator’s line. The shorter the period, the steeper indicator’s chart movements will be.
This parameter is set to 14 by default, and this setting is considered optimal in most cases. You can also adjust the style settings, like line colour and weight.
By using another tab of configuration window, you can change parameters of the levels from 30 and 70 to 20 and 80. You can also add new levels should your trading strategy require so.
Opening Positions on RSI Signals
The main signal the RSI oscillator generates allows defining overbought and oversold price ranges.
Although it is frequently used as a filter in systems where the main indicator is a trend one, it might be possible to try trading using RSI signals only.
When indicator’s line goes above the level 70 or below the level 30, it signals that market is overbought/oversold, and it is necessary to wait for the next signal confirming a trend reversal.
These are the rules for opening positions based on the RSI signals:
- If the indicator’s line crosses the level 70 from above, a short position (Sell) is opened.
- If the indicator’s line crosses the level 30 from below, a long position (Buy) is opened.
There are several conditions for closing a trade:
- Place a Stop Loss to local extremum and Take Profit to the value that is by 2-3 times greater.
- Exit on opposite indicator’s signal.
- Place a Stop Loss and Take Profit to the nearest key levels or Fibonacci (here Take Profit level should be not less than Stop Loss otherwise it is better to hold back and avoid opening a trade).
However, trading using RSI signals only is not the best approach as it has been designed to be used as a filter and not the main instrument.
A trading strategy will be more efficient when using a trend indicator or at least paying attention to the Price Action signals.
Combined Strategy using Stochastic + RSI
In order to boost trading efficiency, it’s best to use the Stochastic Oscillator. The absence of trend indicators in this trading strategy is compensated by simultaneous analysis of two timeframes.
This way the oscillators will filter each other’s signals and trades will be opened only when both indicators give the same signals on different time frames.
This strategy suggests using time frames of Н4 and М15. In Н4, the RSI will have the default settings.
The only difference will be that instead of levels 30 and 70 we will set it at 50. In М15, Stochastic will have default settings.
Short position (Sell) will be opened in the following case:
- In Н4, the RSI line is crossing the level 50 from below.
- In М15, Stochastic lines exit overbought zone and heads down.
Long positions (Buy) will be opened in the opposite case.
Stop Loss and Take Profit are fixed and set at distances 20 and 50 points from the opening price respectively.
Such ratio enables to obtain a positive statistical expectation from trading in the long run.
It is recommended to check the economic calendar before opening positions in this trading system since the release of important news can significantly influence price movement, and technical analysis won’t be relevant at this very moment.
Advanced Strategy RSI + Stochastic + МА
Finally, let’s consider strategy with three classic indicators filtering each other as a single set and giving powerful signals for entering the market.
This strategy fits best for trading on Н1, Н4 and D1.
First, it is necessary to set up the following indicators in the chart:
- A moving average with the period of 10.
- An RSI with standard settings (levels 70 and 30).
- A Stochastic oscillator with standard settings (levels 80 and 20).
According to this strategy, a long position is opened when the following signals are generated:
- Price is crossing МА from below.
- RSI and Stochastic exit oversold zone.
All three signals should be received during three candles, otherwise, they will lose their value.
Short positions (Sell) should be opened in the opposite case.
Exiting an open trade should be done when RSI enters the opposite zone. Sometimes, an opposite position can be opened simultaneously with closing previous position, granting other signals to follow the above mentioned pattern.
How is RSI Used in Day Trading?
When looking at how to use the RSI indicator for day trading, it is important to remember that day trading involves buying or selling underlying assets within the same trading day. Effective day trading is not merely about quantity (taking many trades within a single day) but rather about quality (taking the best high probability short-term trades). RSI trading strategies can help traders to identify and take advantage of the best intraday opportunities in both ranging and trending markets.
When trading with RSI, traders also watch out for overbought and oversold signals. While the default RSI setting is 14-periods, day traders may choose lower periods of between 6 and 9, so that more overbought and oversold signals are generated. Ideally, these levels should correspond with support and resistance levels. Thus, in a ranging market, buy orders will be placed off a support area when the RSI reading is below 30, whereas sell orders will be placed off a resistance area when the RSI reading is above 70.
In trending markets, the RSI setting can be even lower (2-6). In this way, traders can identify the best value areas to enter the market in the direction of the dominant trend. For instance, in an uptrend, traders will look to enter buy trades after a pullback that will be indicated by an oversold RSI reading. Similarly, in a downtrend, sell trades will be placed after a retracement that will be highlighted by an overbought RSI reading. Because a lower setting will generate numerous overbought and oversold signals, it is important to combine RSI and other technical indicators, such as moving averages, in trending markets so as to filter out the best quality signals when day trading. Moving averages will confirm the trend and also provide possible retracement target levels where RSI overbought and oversold signals can confirm solid trading opportunities.
