What Is MetaTrader 5 and Why Is It the Gold Standard for Automated Trading?
MetaTrader 5 has become the default platform for automated forex trading. But what makes it special, and why do 80% of forex trading bots — including PipReaper — run on MT5?
MetaTrader 5: The Platform Behind Modern Automated Trading
MetaTrader 5 (MT5) is a multi-asset trading platform developed by MetaQuotes Software. Originally released in 2010, it has evolved into the most widely used platform for automated forex trading, with support from over 80% of retail forex brokers worldwide.
Why MT5 Over MT4?
While MetaTrader 4 remains popular, MT5 offers significant advantages for automated trading:
| Feature | MT4 | MT5 |
|---|---|---|
| Programming Language | MQL4 | MQL5 (faster, object-oriented) |
| Timeframes | 9 | 21 |
| Pending Order Types | 4 | 6 |
| Built-in Indicators | 30 | 38 |
| Strategy Tester | Single-threaded | Multi-threaded |
| Depth of Market | No | Yes |
| Economic Calendar | No | Built-in |
Key MT5 Features for Automated Trading
Expert Advisors (EAs)
EAs are the core of MT5's automation capabilities. These are programs written in MQL5 that can analyse markets, generate signals, and execute trades automatically without any human intervention.
PipReaper uses the EA framework to connect its AI engine to your broker, translating machine learning predictions into precise trade execution.
Multi-Threaded Strategy Tester
MT5's strategy tester can utilise all CPU cores simultaneously, making backtesting dramatically faster than MT4. This is critical for AI-based systems that need to test across multiple timeframes and conditions.
Depth of Market (DOM)
The DOM window shows real-time order book data, giving automated systems additional data points for entry and exit decisions.
Built-in Economic Calendar
MT5 includes an integrated economic calendar that EAs can read programmatically. This allows bots like PipReaper to adjust behaviour around high-impact news events automatically.
Getting Started with MT5
- Open an account with an MT5-compatible broker (we recommend IC Markets or Pepperstone)
- Download MT5 from your broker's website or the MetaQuotes site
- Log in with your broker credentials
- Install your EA — for PipReaper, this takes under 10 minutes
MetaTrader 5 is free to use. You only pay trading costs (spreads and commissions) through your broker. There's no platform fee.
Why PipReaper Chose MT5
We built PipReaper on MT5 for three reasons: speed (MQL5 executes faster than MQL4), reliability (25+ years of MetaQuotes engineering), and accessibility (available at every major broker). This means you can run PipReaper wherever you already trade.
