What is algorithmic trading?

Algorithmic trading, also known as a program or automated trading, refers to using computer algorithms to place trades automatically.

Algorithms are sets of rules used to determine when and how to trade. They can execute orders based on a predetermined strategy or automatically adjust orders in response to market conditions.

Why use algorithmic trading?

Several reasons exist why investors might choose to use algorithmic trading strategies:

1. To minimise costs – Automated trading can help traders avoid costly mistakes by placing orders quickly and efficiently. It can also help them take advantage of price discrepancies between different markets and exchanges.

2. To minimise risk – Algorithmic trading can help traders limit their exposure to risk by automatically adjusting their orders in response to market conditions.

3. To improve returns – Algorithmic trading can help traders maximise their profits by automatically executing trades based on predetermined rules.

How does algorithmic trading work?

There are three main algorithmic trading strategies: discretionary, arbitrage and hedging.

1. Discretionary algorithms are used by human traders who decide when and how to trade. They rely on news, analysis, and intuition to decide which stocks to trade and when to trade them.

2. Arbitrage algorithms exploit price discrepancies between different markets. For example, a trader might buy stock in one market and sell it immediately in another market for a higher price. This strategy relies on the belief that the prices of stocks will eventually converge.

3. Hedging algorithms are used to minimise risk by automatically adjusting orders in response to market conditions. For example, a hedging algorithm might sell a stock if the price begins to fall below a certain threshold.

How is algorithmic trading regulated in Hong Kong?

Algorithmic trading is regulated in Hong Kong by the Securities and Futures Commission (SFC). The SFC has put rules governing how algorithmic trading can be used and specifying the responsibilities of brokers and traders who use algorithmic trading strategies.
