Lesson summary
Algorithmic trading turns rules into execution.
Mental model
Getting algorithmic trading straight
Algorithmic trading turns rules into execution. The edge is not that a computer trades; the edge is whether the rules survive data, fees, latency, and changing markets.

- Why backtesting matters
Mechanics
How to reason about algorithmic trading
A strategy defines signals, sizing, execution, exits, and risk controls.
Backtests check historical behavior, but assumptions decide whether the test is useful.
Paper trading and small live tests expose operational issues.
- Algo trading executes pre-programmed rules
- Backtesting validates a strategy on past data
- Out-of-sample testing guards against overfitting
Example
A concrete algorithmic trading example
A momentum bot may look profitable on candle closes, then fail live because entries slip and fees eat the edge.
Common mistakes
The usual algorithmic trading trap
Overfitting is the classic trap: a strategy is tuned to past noise and looks impressive until conditions change.
Risk notes
Before you rely on algorithmic trading
Bad data, look-ahead bias, latency, API errors, hidden leverage, and kill-switch failures can break automated systems.
- Define the rule clearly enough to audit.
- Include fees and slippage.
- Set a kill switch and max loss.
Practice
Practise algorithmic trading before moving on
- Define the rule clearly enough to audit.
- Include fees and slippage.
- Set a kill switch and max loss.
Review
Key terms
- Algorithmic Trading
- Using pre-programmed rules to automatically place and manage trades, removing emotion and enabling speed.
- Leverage
- Borrowed capital used to amplify a position — magnifying both gains and losses.
- Slippage
- The difference between expected and executed price, common in low-liquidity or fast markets.
- Latency
- The delay between an action and its effect — critical in fast trading.
- Backtesting
- Testing a strategy on historical data before risking real capital.
