How Algorithmic Trading Works
Algorithmic trading operates by following predetermined trading criteria. Traders employ trading algorithms, computer programs that determine when to execute trades. These algorithms are coded to adhere to a set of predetermined conditions, enabling automated decision-making without the need for constant manual monitoring. One popular example is the usage of moving averages. For instance, a trader may program an algorithm to purchase 50 shares of a stock once its 50-day moving average surpasses its 200-day moving average. Conversely, the algorithm would sell shares if the 50-day moving average falls below the 200-day moving average.
To Trade or Not to Trade? The Truth Behind Trading’s Good, Bad, and Ugly
By continuously monitoring stock prices and moving average indicators in real-time, algorithmic trading algorithms automatically execute buy and sell orders once the specified conditions are met. This automation eliminates the requirement for constant vigilance and intervention by the trader, allowing for faster and more efficient trade execution.
| Step | Action |
|---|---|
| 1 | The algorithm monitors the stock’s price and moving average indicators. |
| 2 | The 50-day moving average goes above the 200-day moving average, indicating a potential buying opportunity. |
| 3 | The algorithm automatically executes a buy order for 50 shares of the stock. |
| 4 | The algorithm continues to monitor the stock’s performance. |
| 5 | The 50-day moving average falls below the 200-day moving average, indicating a potential selling opportunity. |
| 6 | The algorithm automatically executes a sell order to liquidate the position. |
