What are the Most frequently Used Algorithmic Trading Strategies?

Innovations and advancements have equipped traders with various Algo trading strategies. Here are some of the most common Algo Trading strategies:

Trend-Following Strategy

Market trends and changing factors often influence financial markets. Market indicators like price & cost changes, moving averages, channel eruptions, and technical factors often affect trend-following strategy.

Moreover, a trend-following strategy is easy to execute as it does not predict or anticipate future prices. It performs trading activities by learning about the current market scenario and trends. Therefore, the algorithms train models to gain real-time market insights. It reduces complexities by not using convoluted predictive analysis.


A strategy where traders purchase stocks at a lower price and simultaneously sell them at a higher price to benefit from the difference is known as arbitrage. It helps traders procure maximum outcomes from the dynamic nature of price changes due to market developments.

The ephemeral fluctuations in market conditions affect the price and value of stocks. As a result, algorithms help detect patterns and simulate conditions to train and develop models for trading activities. Therefore, the arbitrage strategy helps traders gain desired results by leveraging the opportunities due to market fluctuations that impact prices.

Index-Fund Rebalancing

Index-Fund refers to a type of mutual or exchange-traded fund that gains results due to the market index. Index funds identify rebalancing intermissions to direct funds back to their respective indices. As a result, this offers traders insight into the expected asset activity. Hence, they leverage the opportunity to gain optimum results.

Quantitative Trading Strategies

Quantitative Trading Strategies use quantitative analytics and statistics to determine price changes and asset values. It systematizes models to evaluate insights based on mathematical and statistical methods using data. 

The delta-neutral trading strategy is a suitable example as it uses a mathematical model and includes the complete delta. Here a delta refers to the ratio that compares asset prices and values with a parallel price change that may occur due to various factors.

Mean Reversion Strategy

While studying statistics, you may have come across the term “regression toward the mean”. The mean reversion strategy may imply a similar technique during trading activities. That is to say, a stock price may reach extreme values due to market factors and will revert to the original value in a specific interval. Hence, traders often leverage this strategy to determine patterns and develop models to procure maximum returns.
