What is the difference between AI trading and algorithmic trading?

Question

Accepted Answer

Good question — these terms get used almost interchangeably, but they're genuinely different things.

Algorithmic trading

Algorithmic trading means executing trades according to a pre-programmed set of rules. A human writes the rules; the machine just follows them, faster and without emotion. Examples:

Buy when price crosses above the 50-day moving average
Place a limit order that splits a large buy into smaller chunks to avoid moving the market
Arbitrage: buy on exchange A, sell on exchange B the moment the price gap appears

The key trait: the logic is fixed and transparent. If you could look at the code, you'd see exactly why it trades. It doesn't learn or adapt on its own — it does the same thing every time the same conditions appear.

AI trading

AI trading is a subset that uses machine learning models to derive the rules or make predictions, rather than a human specifying them. Examples:

A neural network trained on years of price/volume data to predict near-term direction, then trades on that prediction
A model that finds patterns in market data a human might never notice
Sentiment models that parse news/social media and adjust strategy accordingly

The key trait: the model learns from data and can keep updating as new data arrives. You don't always know why it makes a given decision — that's the "black box" criticism.

The practical difference

	Algorithmic	AI
Who decides the logic	Human, explicitly	The model, learned from data
Adapts over time	No, fixed rules	Yes, retrains/updates
Transparency	High — you can read the rules	Low — often a black box
Speed	Very fast	Fast, plus needs compute for inference
Failure mode	Rule stops working when market regime changes	Model overfits or sees patterns that aren't there

A common real-world setup is both together: an algorithm handles execution (splitting orders, timing), while an AI model generates the signals the algorithm acts on.

One thing worth flagging: "AI trading" is also a heavily misused marketing label. Plenty of crypto trading bots claim to be AI when they're really just algorithmic rule-followers. If someone promises you an "AI bot" with guaranteed returns, that's a red flag regardless of the terminology — the actual trading edge is the hard part, not the label.
