What is Algo Trading? A Beginner Guide for 2026

What is Algo Trading?

Algo trading or Algorithmic Trading is the process of executing trades using pre-programmed instructions. Instead of manually placing orders, you define rules - like entry, exit, stop-loss, and position sizing - and the system executes them automatically.

90% of trades in the US markets are now executed by algorithms. India is catching up fast.

How does it work?

• Strategy: You define logic. Example: Buy NIFTY when 20 EMA crosses above 50 EMA.


• Backtest: Test that logic on historical data to see P&L, win rate, drawdown.


• Deployment: Connect to broker API like AliceBlue, Zerodha, or AngelOne.


• Risk Engine: System automatically applies stop-loss, target, and daily loss limits.

Why Algo Trading is Better than Manual Trading?

1. No Emotions: Algo never fears or gets greedy. It follows rules.

2. Speed: It can scan 500 stocks in milliseconds.

3. Discipline: It won't break your stop-loss.
