Dive into Algorithmic Trading: A Look at How Computers Have Revolutionized Trading

Over the last ten years, Algorithmic Trading has become incredibly popular. In the United States, it makes up around 70% of all trading activity, and in developing countries like India, it accounts for about 40%. Some people think that it is too complicated or out of reach, but that’s not the case. Creating your Algorithmic Trading system can be quite simple if you understand the basics. This article introduces the concept of Algorithmic Trading and explains why it’s better than manual trading. There will be a follow-up article soon to help you build your Algorithmic Trading system from scratch.

Understanding Algorithmic Trading

Algorithmic Trading is all about buying or selling based on predefined rules tested with historical data. These rules can come from technical analysis, charts, indicators, or stock fundamentals. For example, if you have a strategy that says to buy a stock after it’s been in the red for five consecutive days, you can turn this into a trading system. You can even automate it so that buy orders happen automatically when your conditions are met. You can also set stop-loss, target prices, and position sizes in the algorithm, which makes trading easier.

What is Algorithmic Trading?


They say your success in trading depends on 30% market analysis, 30% risk management, 30% controlling your emotions, and 10% luck. Algorithmic systems can handle 90% of that, excluding luck. Many traders fail because emotions affect their decisions. Even experienced traders sometimes panic when buying or selling, leading to losses. Algorithmic systems eliminate these problems linked to manual trading. Plus, if you’re busy with a job and can’t trade throughout the day, you can automate your algorithm, and your computer will trade for you.

Algorithmic Trading vs. Manual Trading

Manual Trading Algorithmic Trading
Involves human emotions Emotion-free
No predefined rules for Buy/Sell Uses predefined, tested rules
Requires constant market monitoring No need for constant monitoring if automated
Emphasizes risk management Risk management is built into the algorithm
Success varies with each execution Algorithmic systems are tested, increasing success chances
May lead to heavy slippages Slippage is significantly reduced in Algorithmic Trading

Algorithmic vs. Automated Trading

A common misconception is that Algorithmic Trading and Automated Trading are the same, but they’re not. While you can automate your Algorithmic strategy, it’s not mandatory. You can still manually execute trades based on signals generated by your Algorithmic system. To automate your Algorithmic strategy, you need exchange approval, which is easy to obtain if your algorithm is error-free. So, when you come across an Algorithmic system, check whether it’s automated or manual.

Dispelling Myths

Let’s debunk some common myths about Algorithmic system:

  • Myth: It requires deep mathematical and statistical knowledge
    Not true. You can turn simple trading rules into algorithms.
  • Myth: It demands significant capital
    False! You can use Algorithmic Trading with small quantities.
  • Myth: It is not for retail traders
    It’s for everyone. If you want to automate your algorithm, you’ll need a dealer terminal from the exchange.
  • Myth: It requires super-fast computers and infrastructure
    This is mainly for high-frequency trading; for most purposes, your PC is sufficient.
  • Myth: Algorithmic Trading and Automated Trading are the same
    Not at all. Algorithmic trading can also be done manually.
