What Is Algorithmic Trading? An Ex-Banker's Honest Explainer
'Algorithmic trading' sounds like a hedge-fund superpower. In plain terms it just means: rules, executed automatically, without emotion. That's it. The mystique is mostly marketing.
After 20 years in banking I've seen both the real edge and the snake oil. Here's the honest version of what it is and what you'd actually need.
What it actually is
You define rules ('if X, buy; if Y, sell'), a program watches the market, and it acts faster and more consistently than you ever could by hand. The benefit is discipline and speed — not magic returns.
What you need to start
- A clear, testable strategy (the hard part).
- A way to run code — Replit lets non-coders build with AI.
- An exchange with an API — e.g. Bitvavo (regulated EU) or Bybit for advanced order types.
The part nobody advertises
Most retail algo strategies don't beat simply holding, after fees and slippage. Automation amplifies whatever edge — or lack of edge — you have. Backtest honestly, include costs, and be sceptical of anything promising consistent returns.
Frequently asked questions
Is algorithmic trading legal?
Yes, for individuals using exchange APIs it's legal in most regions — you're just automating your own orders. Check your local rules and your exchange's API terms.
Can beginners do algorithmic trading?
Technically yes — AI tools remove the coding barrier. But a beginner's edge is usually the strategy, not the code, and that takes study and honest testing. Start tiny.
Does it guarantee profit?
No. This is educational, not financial advice. Automating a losing strategy just loses faster; crypto carries real risk including total loss.
