Technical indicators sometimes make this improbable trading mechanism a bit easier, these mechanisms help the traders to identify the direction, strength, volatility, and possible reversal level in the price action. They also enable the algorithm to use precise information leading to more successful trades. From the Top 8 algorithmic trading technical indicators goes.
1. Moving Averages (MA)
Moving Averages are useful in distorting price data and showing a trend over a set of periods. There are two main types: The unweighted moving average of the price over a certain period of time, Simple Moving Average (SMA); most common in trading longer periods.
The weighted moving average that include the average for the latest price and with the average rapidly gaining popularity in the short-term trading.
Application: In most cases, the moving average is applied in crossover strategies where short-term average moves above long-term average the buying bias is indicated while the opposite is true if the average is shifted below the long term.
2. Moving Average Convergence Divergence (MACD)
MACD is defined as a momentum indicator that is useful in tracking the trend which is based on the difference between the fourteen and twenty eight periods moving averages. Specifically MACD includes the following components:
Histogram: The facial difference between the MACD line and the signal line that explains the intensity of the momentum.
Application: When the MACD line swings and crosses toward the top of the signal line, it is believed to be a good indication as it shows a bullish trend. If the crossing occurs at the bottom it is said to be a bearish signal. This indicator is important to algorithmic traders to determine new momentum and provide buy/sell opportunities.
3. Relative Strength Index (RSI)
RSI provides the rate as well as the degree of price changes that have occurred and is also useful in bounding price extremes. The RSI is defined in values from between 0 – 100:
More than 70: Usually, it shows overbought zone, giving a hint that the prices will be reversed or a likely pullback will occur.
Less than 30: Usually, it shows oversold zone, giving a hint that a likely price bounce or upward move may occur.
Application: The RSI is frequently paired with trend indicators to validate possible reversal signals. Additionally, algorithms use RSI to stay clear of making entry trades during overbought or oversold market conditions.
4. Bollinger Bands
Consists of an amount of average including two standard levers on the above and below lever to the average moving lever which pitch are increasing now.
Upper Band: Moving average plus two standard deviations.
Lower Band: Moving average minus two standard deviations.
Application: When lack of demand or price crosses the upper band, expected overbought situation occurs when price crosses the lower band, indicating over selling conditions. Traders like the Bollinger Bands are commonly used in the mean reversion strategy to buy the dips expecting the prices to return to the average levels.
5. Average True Range (ATR)
ATR is a volatility measure showing the average price range of a security in a set period of time previously defined. It does not show trend direction but rather level of volatility of the market.
Application: ATR is preferred for usage in algorithmic systems for stopping loss and taking profits. The volume and velocity of trades are different when ATR values are higher than that of lower. Larger stop-loss values set by traders may be taken in higher volatility conditions to prevent triggering at normal times.
6. Stochastic Oscillator
The Stochastic Oscillator is widely used as a momentum indicator. It compares a security’s closing price to its previous 14 periods’ highest and lowest prices to get %K and %D readings.
Above 80: Overbought position which is interpreted visually as a possible sell position.
Below 20: Oversold position which is interpreted visually as a possible buy position.
Application: This indicator has several application and it goes well with other indicators to give better results. It is best for range bound or cyclic kind of markets.
7. Volume Weighted Average Price (VWAP)
It averages out and estimates all the price a security has been bought or sold throughout the day with regard to its volume and price. Most institutional traders benchmark their performance against VWAP.
Application: If the price is above VWAP then we can expect bullish sentiment otherwise we will have a bearish sentiment for the price. VWAP is extensively used by algorithmic traders to measure price direction on intra-day charts, it is used in code for mean reversion and also trend following tactics.
8. On-Balance Volume (OBV)
OBV is a momentum indicator that relates price change to volume. It sums the volume for the days with an increase in price and it takes the volume away from the days where the price has dropped.
Application: As long as an OBV rises, then it shows that there is a safe strong buying pressure, and the opposite when the OBV has dropped. This is used by traders in analyzing the trend of a currency, and lock in possible break-out signals later with price action.
9. Fibonacci Retracement Levels
One special technique is Fibonacci retracement that uses a certain number to indicate the level of support and resistance. This particular number is derived from a sequence known as the Fibonacci sequence.
Application: The algorithmic traders technique of using the Fibonacci retracement levels of 23.6,38.2, 50, and 61.8 is particularly useful in determining entry and exit points in the trades and is more useful in cyclic trading. This indicator is especially applicable with synergistic relevance of other indicators to improve strategy robustness.
10. Parabolic SAR (Stop and Reverse)
If there is a trend then this indicator can be used: Parabolic SAR shows the potential for trend reversals by plotting dots above or below the price. If the dots are below the price, the trend is considered bullish. If they are above, it’s bearish.
Application: An intraday trader who employs Trend-Following strategy, can use the Parabolic SAR indicator to anticipate their exit point, this application is important in intraday trading. As a general rule, many algorithms integrate it with the moving average and other indicators to enhance accuracy.
11. Commodity Channel Index (CCI)
In essence, the CCI calculates the difference between the current price and the average historical price in order to understand overbought or oversold levels.
Above +100: Indicates potential overbought conditions.
Below -100: Indicates potential oversold conditions.
Application: It has been observed that CCI works well for identifying cyclical trends and since algorithmic strategies based on cyclical trends are also quite common, it’s also commonly used with trend indicators.
12. Ichimoku Cloud
Ichimoku clouds, or Ichimoku Kinko Hyo, are different versatile indicators which includes support and resistance levels, trend direction and momentum. They have numerous components, namely the Tenkan-sen, Kijun-sen and the cloud which is also called Kumo.
Application: When the price is above the cloud, it is a bullish signal, whereas when it is below the cloud, it is bearish. Ichimoku Cloud is however more efficient in helping one identify long-term trends. It is frequently used in algorithmic trading in which the trader applies a trend following strategy.
13. Rate of Change (ROC)
ROC is one of the most momentum indicators and it measures the current price dissatisfaction relative to some price fixed a certain periods back in history.
Application: ROC enables traders to estimations of momentum. Positive ROC values are attributed to trends with large growth potentials, while negative values are assigned to bearish trends. This indicator can also forecast strength of price trends and its utilized in combination with other indicators for confirmation.
Conclusion
Technical indicators in algorithmic trading enable the analysis of the market trends allowing the traders to adjust their trade strategies with the help of statistics. However, no one single indicator can be called ideal. The indicators need to be used in a mix for the best results. Multiple indicators allow algorithms to increase their accuracy, avoid risks, and take advantage of the opportunities available during trade. Oftentimes, the best strategy requires integrating trend-following indicators with some momentum, volatility and volume indicators to ensure a more well-rounded and evidence-based strategy is designed.
