How does algorithmic trading work?

Algorithmic trading is like having a super-smart robot that helps you buy and sell stuff really fast.

Imagine you're at a lemonade stand, and you want to make sure you always have the best price for your lemonade. You might watch what other stands are charging and change your own price quickly. That’s kind of how algorithmic trading works, but instead of lemonade, it's about stocks, bonds, or other financial things.

The robot (or the algorithm) uses special rules to decide when to buy or sell. It can look at lots of information all at once, like how fast people are buying, what other traders are doing, and even news stories, to make its decisions.

These robots don’t just work in one place; they’re everywhere. They race against each other, trying to be the first to buy or sell. This helps prices change quickly because everyone is acting fast based on the same information.

It’s like a big game of tag, except instead of running around, people are using robots to help them win.
