# Basic concept of algorithmic trading

Algo-trading provides the following benefits: Trades are executed at the best possible prices.

Trades are timed correctly and instantly to avoid significant price changes. Reduced transaction costs.

Simultaneous automated checks on multiple market conditions. Reduced risk of manual errors when placing trades.

Most algo-trading today is high-frequency trading HFTwhich attempts to capitalize on placing a large number of orders at rapid speeds across multiple markets and multiple decision parameters based on preprogrammed instructions.

Algorithmic trading provides a more systematic approach to active trading than methods based on trader intuition or instinct.

Algorithmic Trading Strategies Any strategy for algorithmic trading requires an identified opportunity that is profitable in terms of improved earnings or cost reduction. The following are common trading strategies used in algo-trading: Trend-following Strategies The most common algorithmic trading strategies follow trends in moving averages, channel breakouts, price level movements, and related technical indicators.

## Pick the Right Algorithmic Trading Software

These are the easiest and simplest strategies to implement through algorithmic trading because these strategies do not involve making any predictions or price forecasts.

Trades are initiated based on the occurrence of desirable trends, which are easy and straightforward to implement through algorithms without getting into the complexity of predictive analysis.

### Resources to Start Coding Trading Algorithms

Using and day moving averages is a popular trend-following strategy. Arbitrage Opportunities Buying a dual-listed stock at a lower price in one market and simultaneously selling it at a higher price in another market offers the price differential as risk-free basic concept of algorithmic trading or arbitrage. The same operation can be replicated for stocks vs. Implementing an algorithm to identify such price differentials and placing the orders efficiently allows profitable opportunities.

Index Fund Rebalancing Index funds have defined periods of rebalancing to bring their holdings to par with their respective benchmark indices.

### Basics of Algorithmic Trading: Concepts and Examples

Such trades are initiated via algorithmic trading systems for timely execution and the best prices. Mathematical Model-based Strategies Proven mathematical models, like the delta-neutral trading strategy, allow trading on a combination of options and the underlying security. Trading Range Mean Reversion Mean reversion strategy is based on the concept that the high and low prices of an asset are a temporary phenomenon that revert to their mean value average value periodically.

Identifying and defining a price range and implementing an algorithm based on it allows trades to be placed automatically when the price of an asset breaks in and out of its defined range.

The aim is to execute the order close to the volume-weighted average price VWAP.

Time Weighted Average Price TWAP Time-weighted average price strategy breaks up a large order and releases dynamically determined smaller chunks of the order to the market using evenly divided time slots between a start and end time. The aim is to execute the order close to the average price between the start and end times thereby minimizing market impact.

Percentage of Volume POV Until the trade order is fully filled, this algorithm continues sending partial orders according to the defined participation ratio and according to the volume traded in the markets. Implementation Shortfall The implementation shortfall strategy aims at minimizing the execution cost of an order by trading off the real-time market, thereby saving on the cost of the order and benefiting from the opportunity cost of delayed execution. The strategy will increase the targeted participation rate when the stock price moves favorably and decrease it when the stock price moves adversely.

This is sometimes identified as high-tech front-running. The challenge is to transform the identified strategy into an integrated computerized process that has access to a trading account for placing orders. Network connectivity and access to trading platforms to place orders.

Access to market data feeds that will be monitored by the algorithm for opportunities to place orders. Can we explore the possibility of arbitrage trading on the Royal Dutch Shell stock listed on these two markets in two different currencies?

Requirements: A computer program that can read current market prices. Order-placing capability that can route the order to the correct exchange. Backtesting capability on historical price feeds.
