How to Use Oscillators to Pinpoint Market Extremes


For currency analysis, technical indicators and oscillators are often used by forex traders. Use of forex oscillators can help traders spot market extremes. Turning moments on the chart, often even before the price really reverses.

You can enhance your trading performance by being proficient in the application and analysis of several technical oscillators.

What is Technical Trading Oscillators

Price information on chart is taken into account by mathematical method that is represented visually by a technical oscillator. Oscillator often has two opposing levels that can be utilised to determine the market.

Leading indicators are a category that includes price oscillators. This is because they might provide as an early alert or indication regarding a prospective price event on a chart. For traders attempting to trade price extremes or retracements inside a trend, they are particularly helpful tools in this way.

However, there are several drawbacks to using technical oscillators. Prior to the actual price event, oscillators are prone to sending out a lot of erroneous trade signals. The lagging indicators, such as moving averages, on the other hand, are somewhat more trustworthy, but their signal typically arrives with a longer wait.

Basic Forex Oscillator Strategy

To obtain early buy and sell signals—more precisely, overbought and oversold signals—using Forex oscillators is the basic notion. When prices are being pushed too far in one way, oscillators can alert you. And when that takes place, we can anticipate a rubber band effect in which prices snap back or start to regress to the mean.

Buy Oscillator Signal

When the oscillator indicator displays an oversold value, a basic purchase signal is generated. This suggests that there may be too many selling in the market and that a negative market extreme may be approaching. As a result, an oversold oscillator alerts traders to the possibility of a chart moving upward.

Sell Oscillator Signal

When there is an oscillator sell signal, the opposite is true. This indication appears when the oscillator is overbought, indicating that there may be an excessive number of purchasers driving the market to an extreme bullishness. Thus, the oscillator alerts traders to a possible downward turning point on the chart.

Divergence of the Oscillator

Utilizing oscillators in conjunction with divergence patterns is one of the greatest methods to include them in your trading strategy. A divergence often occurs when the oscillator and price action are moving in opposite directions. Typically, a trade is entered in the oscillator’s direction.

Best Oscillators and Indicators

Now that you know the fundamental reasoning behind this kind of technical analysis, let’s talk about some of the top oscillators and technical indicators for Forex trading. If you have never used an oscillator before, I think this will be a useful introduction lesson that will provide you the fundamental knowledge you need to get started.

Relative Strength Index

The Relative Strength Index, or RSI, is the first oscillator we’ll talk about. The RSI is a single line with two present levels of 30 and 70 that oscillates between the 0-100 ranges.

The oscillator receives purchase signals when it is in the oversold zone (0–30). The overbought zone that causes oscillator sale signals is between 70 and 100.

Two formulas are used to calculate the RSI line:

Relative Strength (RS) = Average Gain / Average Loss


RSI = 100 – [100 / (1+RS)]

The average gain and average loss are supposed to be determined by taking into account 14 periods on the chart, according to the default 14-period value of the RSI. You figure out the average of all price rises over the last 14 periods as shown on the chart. The average of all the losses (price declines) on the chart for the previous 14 periods is then calculated.

You can finish the RSI formula once you’ve located the RS.

Trading divergence is a great application for the RSI Indicator. When the price action forms lower bottoms while the RSI forms higher bottoms, there is a positive divergence. When the price movement makes higher highs but the RSI closes at lower highs, there is a bearish divergence. Keep in mind that the idea behind divergence is to profit from the current momentum’s expected decline, which could result in a potential reversal.

Stochastic Oscillator

This is yet another really well-liked oscillator indication. The 2-line Stochastic Oscillator is an indicator that oscillates between 0 and 100. The oversold zone remains between 0 and 20, while the overbought zone is situated between 100 and 80.

Traders interpret the crossing of the two stochastic lines into the 0-20 region as an oversold (buy) signal. This is an overbought (sell) signal when the two lines cross through the 80–100 region.

Two formulas are used to calculate the stochastic oscillator:

%K = (current close – lowest low) / (highest high – lowest low) x 100

%D = 3-period SMA of %K

14 chart periods are taken into account by the Stochastic Oscillator’s present structure. The lowest position during the previous 14 periods is referred to as the “Lowest Low.” The same is true for “Highest High,” which refers to the highest point on the chart for the previous 14 periods. The decimal point is moved two digits by multiplying by 100.

Similar to how you would use the RSI momentum indicator, you can trade divergences using the stochastic oscillator. When the Stochastic provides higher bottoms while the market movement creates lower bottoms, this is known as a bullish divergence. When the market action is still producing higher peaks while the Stochastic is producing lower tops, there is a bearish divergence.

Momentum = (close price of the current period / close price 14 periods ago) x 100

The Momentum Oscillator

Momentum Oscillator is the last oscillator we’ll talk about. Another indicator, this one a single line plotted with values often ranging from 99 to 100, is typically connected to the bottom of the chart.

The price at the present time and the price from a predetermined number of periods ago are compared in order to calculate the momentum oscillator. 14 chart periods are taken into account by the momentum indicator’s default settings. The momentum indicator formula is listed below:

Momentum is equal to (current period’s close price minus last period’s close price) x 100.

Accessing the momentum line’s direction yields the momentum signal. As a general rule, the Momentum Indicator will indicate a long bias when the line is ticking upward. This will give a short bias when the line is moving downhill.

Apart from that, the Momentum indicator is an excellent tool for trading divergences, which is where its main power lies. Bullish divergence, which predicts an impending price gain, occurs when the bottoms of the Momentum oscillator are rising while the bottoms on the chart are falling. There is a bearish divergence that indicates a potential price decline when the tops of the momentum indicator are falling and the tops of the price action are rising.

Combining Technical Oscillators

Whatever technical oscillator you use, using it alone would not be a very good idea because of all the misleading indications you might receive. In order to provide extra support for the trade, it is always a good idea to combine an oscillator with another sort of non-correlated analysis, such as Support and Resistance, Harmonic patterns, Elliott wave analysis, or another type of research.

To verify their signals, some traders like to combine two oscillators. Remember that the above indicators are distinct but highly correlated, thus they won’t offer non-correlated confluence but instead can provide an additional level of confirmation for your favourite oscillator.

I’ll combine the Stochastic Oscillator and Relative Strength Index in the following example. Only when both indicators are sending out matching indications will I enter the market. I will then continue holding my position until the RSI gives me a signal to sell. Overbought/oversold signals, divergence, or rising/falling tops or bottoms are examples of exit signals.
