Automated trading means a system carries out trades on its own once it is set up: watching the market, deciding when to act, placing orders, managing stops and closing positions. Automation can be partial, such as automatic stop management on manually entered trades, or complete, where a strategy runs end to end without human clicks. It removes much of the emotion and inconsistency that hurt manual traders, but it introduces new risks: software bugs, broken connections and strategies that keep trading when they should stop.

## Levels of automation

| Level | Human role | Example |
|---|---|---|
| Alerts only | Human decides and trades | Price or indicator alerts. See [Alerts and Webhooks](https://learn.tradelabsai.com/programming/alerts-and-webhooks/) |
| Semi automated | Human approves; system executes | One click trade tickets from signals |
| Automated exits | Human enters; system manages stops and targets | Bracket orders, trailing stops. See [Bracket Orders](https://learn.tradelabsai.com/orders/bracket-orders/) |
| Fully automated | System enters, manages and exits | Trading bots, expert advisors |
| Supervised automation | System runs; humans monitor and intervene | Most professional systematic trading |

Most professional firms run fully automated strategies with continuous human supervision.

## Platform options

| Platform | Typical use |
|---|---|
| Broker APIs with Python or other languages | Custom systems with full control. See [Working With Exchange and Broker APIs](https://learn.tradelabsai.com/programming/trading-apis/) |
| TradingView with alerts and webhooks | Signals from Pine Script sent to execution services. See [Pine Script Basics](https://learn.tradelabsai.com/programming/pine-script-basics/) |
| MetaTrader expert advisors | Forex and CFD automation in MQL. See [MetaTrader](https://learn.tradelabsai.com/industry/metatrader/) |
| NinjaTrader strategies | Futures automation in C#. See [NinjaTrader](https://learn.tradelabsai.com/industry/ninjatrader/) |
| Crypto exchange APIs | Bots on centralised exchanges |
| Open source frameworks | Backtrader, NautilusTrader, freqtrade and others |

## What to automate first

1. **Risk management:** automatic stops, position size calculation and daily loss limits. See [Maximum Trade Risk and Daily Loss Limits](https://learn.tradelabsai.com/risk/daily-loss-limit/).
2. **Repetitive tasks:** scanning, alerts and order placement.
3. **Exits:** trailing stops and time stops, which humans often mishandle emotionally. See [Exit Mechanics](https://learn.tradelabsai.com/position-management/exit-mechanics/).
4. **Full strategies** only after they are tested and understood.

## Designing a robust automated system

| Element | Why |
|---|---|
| State tracking | The system must always know its current positions and open orders |
| Reconciliation | Compare internal records with the broker's records regularly. See [Trade Accounting and Reconciliation](https://learn.tradelabsai.com/industry/trade-reconciliation/) |
| Restart safety | After a crash, the system should resume without duplicating orders |
| Risk limits | Maximum position, order size and daily loss caps. See [Risk Controls and Kill Switches](https://learn.tradelabsai.com/algo-trading/risk-controls-and-kill-switches/) |
| Logging | Record every signal, order, fill and error. See [Logging, Audit Trails and Incident Response](https://learn.tradelabsai.com/algo-trading/audit-trails/) |
| Alerts | Notify humans of errors, disconnections and unusual activity |
| Kill switch | A fast way to stop trading and flatten positions |

**Example: A duplicate order bug**
An automated strategy loses its internet connection just after sending a buy order. When it reconnects, it does not see a confirmation and sends the order again. Both orders fill, doubling the intended position. A well designed system would query the broker for open orders and positions before resending, use unique client order IDs and enforce a maximum position limit that blocks the second order. See [Alerts, Error Handling and Reconnection](https://learn.tradelabsai.com/algo-trading/error-handling/).

## Benefits

- **No emotional interference** with entries and exits.
- **Consistency** across every trade.
- **Ability to trade many markets** and around the clock.
- **Precise execution** of complex rules.

## Risks

- **Technical failures:** power, internet, server or broker outages. See [Failover, Backups and Disaster Recovery](https://learn.tradelabsai.com/algo-trading/disaster-recovery/).
- **Bugs** that send wrong orders.
- **Market changes** the system was not designed for. See [Structural Breaks and Regime Changes](https://learn.tradelabsai.com/math/regime-changes/).
- **Overconfidence** in backtests. See [From Backtest to Live: Paper, Shadow and Canary](https://learn.tradelabsai.com/algo-trading/backtest-to-live/).
- **Unattended trading during extreme events.**

## Frequently asked questions

### What is automated trading?

Trading in which software watches markets, places orders and manages positions without manual input once it is set up.

### Is automated trading safe?

It can be if built with strong risk limits, state tracking, reconciliation, logging and human monitoring; without them, bugs and outages can cause large losses.

### What should I automate first?

Risk management tasks such as stops, position sizing and daily loss limits, before automating full strategies.
