What is MetaTrader: The Complete Guide

Opening block

You are a retail forex or CFD trader, an algorithmic developer, or an investor deciding on platforms. This guide is for you.
You need a practical, hands-on introduction to MetaTrader. You need clear steps and concrete numbers. You need to know which version fits your plan.

This article solves three problems. Explain what MetaTrader is. Compare MT4 and MT5. Show which features matter for trading, automation, and costs. Walk through installation, account setup, core tools, and common pitfalls. Give time estimates, file types, order counts, and price ranges.

This article promises clear steps. Provide concrete numbers for timeframes, order types, setup steps, and cost ranges. Offer a short decision tree at the end to help you choose between MT4, MT5, mobile, and broker web options. Expect checklists you can act on in 1–3 days and metrics you can measure.

Quick Answer / TL;DR

If you want a simple, stable forex platform → use MetaTrader 4 (MT4). MT4 commonly offers 9 chart timeframes.
If you need multi-asset trading and advanced order types → use MetaTrader 5 (MT5). MT5 expands to 21 chart timeframes and extra order types.
If you want automation → deploy Expert Advisors (EAs) (Expert Advisor is an automated trading script). Use three approaches: buy, code, or hire. Developer rates typically range from $20 to $100 per hour.
Quick-start: 1) Download the app (1–2 minutes). 2) Open a demo account (instant). 3) Open a live account (verification 1–3 days). 4) Test on demo for 100–1,000 trades before going live.

Definition and Core Features — 3 Key Components

Define MetaTrader as a family of electronic trading platforms (client software). Two main versions exist: MetaTrader 4 (MT4) and MetaTrader 5 (MT5). Brokers run the server-side. You connect as a client over the internet. Expect data exchange measured in milliseconds for normal setups.

List three core capabilities. First, real-time charting with built-in indicators. MT4 typically includes about 30+ built-in indicators. MT5 typically includes about 50+ built-in indicators. Second, order execution across market and pending orders. Third, automation via Expert Advisors (EAs) (automated strategies) and custom indicators.

Break down the differences with concrete numbers. MT4 commonly provides 9 chart timeframes. MT5 expands to 21 timeframes. MT4 file extension for compiled code is .ex4. MT5 uses .ex5. MT4 strategy testing is single-threaded on one CPU core. MT5 supports multi-threaded testing across multiple cores.

Describe who uses MetaTrader. Manual FX traders run 1–3 charts and 1–3 indicators on a laptop. Algo developers prototype with 10–100 indicator variants and 1–3 EAs. Brokers and prop shops deploy 10+ parallel strategies on servers. VPS users pay $5–$30 per month to run 24/7.

Explain why MetaTrader matters. Download takes under 2 minutes on broadband. The community offers thousands of indicators and EAs. Hundreds of brokers support MetaTrader. Barrier to entry is low. Ecosystem size reduces development cost and time.

Watch out for: MetaTrader is software, not a broker or liquidity provider. Check the broker’s execution model, spreads, commissions, and slippage before trusting live results.

Installing and Setting Up — 6 Quick Steps

High-level 6-step checklist with approximate times. Expect a simple setup of 10–30 minutes for demo use. Expect live account verification to add 1–3 days. Expect EA installation and testing to take 30 minutes to several hours based on complexity.

1) Download the client or mobile app — typically takes under 2 minutes on broadband for the desktop installer (10–50 MB).
2) Open a demo account — activation is instant. Demo balances commonly range from $10,000 to $1,000,000. Choose a sensible balance like $10,000 for realistic risk tests.
3) Verify identity for a live account — brokers commonly take 1–3 days to approve KYC (document upload and review). Some brokers approve in hours; others take longer.
4) Configure charts and timeframes — save a workspace in 1–2 minutes. Use templates to apply indicators across 3–10 charts.
5) Install indicators/EAs (.ex4 for MT4, .ex5 for MT5) — copy files and restart; takes under 1 minute for simple installs. Test on demo immediately.
6) Connect to a VPS if running EAs 24/7 — expect monthly VPS cost of $5–$30 and targeted uptime above 99.9%.

Describe platform variants. Desktop runs on Windows; Mac support often requires wrappers or third-party tools. Web builds run in most browsers with no install; expect limited indicator support. Mobile apps (iOS and Android) are compact, usually 10–50 MB, and update every few weeks.

Use these setup tips:
– Enable auto-login to avoid repeated credentials.
– Save chart templates and profiles; use 3–5 templates for different strategies.
– Set stop loss (SL) and take profit (TP) defaults in the order dialog.
– Back up profiles and the MQL source files (.mq4/.mq5) regularly.

Watch out for: Do not start live trading with untested EAs. Test at least 100 demo trades or simulate one month of market time. Prefer 1,000 demo trades for higher confidence.

Trading Tools and Order Types — 5 Essentials

Describe five essential tools you will use daily.
1) Charting — real-time candles, bars, and lines; use 9 timeframes in MT4 or 21 in MT5.
2) Indicators — roughly 30+ built-ins in MT4 and 50+ in MT5; thousands of custom indicators exist.
3) Strategy tester — MT4 runs on a single CPU core; MT5 supports multi-core backtesting. Expect a 1,000-trade backtest to take minutes on MT5 and up to hours on MT4 depending on tick data.
4) Market Watch / tick window — monitor bid/ask and volume; useful for scalping where a few pips matter.
5) Depth of Market (DoM) — available in MT5 for some brokers; shows multiple price levels and volume on each level.

Enumerate order types with counts. MT4 supports the four common order types: market, limit, stop, and stop-limit (4 types). MT5 adds extra order types and 6 fill/execution modes for exchange-style trading. Also expect buy stop, sell stop, buy limit, sell limit, and trailing stop options.

Explain indicators and scripts. Built-in indicators cover moving averages, RSI, MACD, and Bollinger Bands. Custom indicators compile into .ex4 or .ex5 files. Thousands of community indicators exist; prices range from free to several hundred dollars.

Give practical examples. Set a 10-pip stop loss and a 20-pip take profit on EUR/USD for a 1:2 reward-to-risk ratio. Use a 0.01 lot trade to risk roughly $1 per pip on many brokers; adjust size for account equity. Run a 1,000-trade backtest; with high-quality tick data and MT5 multi-core testing, expect run times from under 5 minutes to 1 hour.

Watch out for: slippage and requotes. Expect slippage of 0 to 2 pips in normal conditions and 5 to 10+ pips in extreme volatility. Check the broker’s execution model: ECN, STP, or market maker change spreads and slippage frequency.

Customization and Automation — 3 Ways to Automate

Overview of automation options. Buy premade EAs, write your own in MQL4/MQL5 (MetaQuotes Language), or hire a developer. MQL4 maps to MT4 and MQL5 to MT5. Use automation when you want rules-based trading or 24/7 monitoring.

Coding specifics and expectations. Simple indicators can be 20–200 lines of code. A medium EA typically runs 100–1,000 lines. Development time commonly ranges from 10 to 100+ hours depending on complexity. Compile to .ex4 or .ex5 and test on demo.

Costs and marketplace figures. Premade EAs sell from $10 to $500. Freelance developers charge $20 to $100 per hour. Expect a competent custom EA to cost $500 to $5,000 depending on features and testing. Consider buying source code when available; source can range from $200 to several thousand.

Describe deployment and hosting. Run EAs on your PC for small setups. Use a VPS for 24/7 operation. Typical VPS cost ranges from $5 to $30 per month. Aim for VPS uptime of 99.9% and latency under 50 milliseconds to your broker’s server. Monitor CPU usage; a single EA rarely needs more than 5–10% of a modern core, but running 10+ strategies can use multiple cores.

Watch out for: backtest overfitting. Do not chase perfect historical returns. Validate with out-of-sample tests of 20% to 50% of the data and run forward tests of 100–1,000 trades.

Comparison table

Closing

Make a quick decision with this mini decision tree. Follow the single-path steps below.

• If you trade primarily forex and want stability → choose MT4. Expect 9 timeframes and ~30+ indicators. Use premade EAs or small custom scripts.
• If you trade stocks, futures, or need advanced order types and faster backtests → choose MT5. Expect 21 timeframes, multi-core testing, and extra order types.
• If you need mobility for basic trades or position checks → use the Mobile App. Expect reduced indicator and customization counts but full trade execution.
• If you prefer no install and broker-integrated features → use the Broker Web platform for quick access. Expect variable features; check counts for indicators and order types.

Actionable checklist before you trade live:
1) Download and install the chosen client (1–2 minutes).
2) Open a demo account and set balance (choose $10,000 or $100,000). Run 100–1,000 demo trades.
3) If automating, decide: buy an EA ($10–$500), hire a developer ($20–$100/hour), or code it yourself (10–100+ hours).
4) If running 24/7, rent a VPS for $5–$30/month and aim for 99.9% uptime.
5) Verify broker fees: spread 0.0–3.0 pips on major pairs, commissions $0–$10 per side, and slippage expectations.

Final tips: Test thoroughly for at least 100 trades or one month of market time. Monitor drawdowns; expect periodic drawdowns of 5%–30% depending on strategy. Keep backups of source code and templates. Check execution model and latency before depositing large sums. Start small. Scale with metrics: win rate, average profit per trade, max drawdown, and equity curve stability.
