Before an Expert Advisor (EA) trades your money, you need to know what its settings mean in money: how big a trade is, what it costs, what a stop really protects, and which broker holds the account. These free guides cover those basics, one topic per page, the way MetaTrader 5 (MT5) uses them.
Read them in order. Each one builds on the one before, and the worked examples carry through: the 0.40-lot trade sized on the first page is the one the next two pages put a margin, a commission and a swap on.
0.1
What points, pips and lots mean in MT5, how to turn a stop in pips into money, and how to work out a lot size from the amount you're willing to lose.
Read the guide →0.2
What leverage changes and what it doesn't, how MT5 works out the margin a trade needs, and what happens at a margin call and a stop out.
Read the guide →0.3
The three costs every trade pays, where MT5 shows each one, and why commission changes the lot size your risk allows.
Read the guide →0.4
Why a stop is a limit and not a guarantee, who holds it, the minimum distances a broker sets, and MT5's order types, expiry rules and filling policies.
Read the guide →0.5
How to check a broker at its regulator, spot a clone firm, confirm the broker allows what your EA does, and open a demo that matches the account you'd use live.
Read the guide →Keep MT5 open as you read. Most of what these pages describe is in a symbol's Specification window (Market Watch, right-click the symbol, Specification), and the figures there are your broker's, not ours.
The examples are illustrative. Prices, costs and rules differ from broker to broker and change over time, so always read your own.
These guides don't recommend a broker or an Expert Advisor. Our reviews of individual EAs are separate, each with the evidence behind its verdict, on Best Expert Advisors.
The MT5 details in these guides were checked against MetaQuotes' MetaTrader 5 help and MQL5 reference, and the regulator details against each regulator's own website, in October 2026.
Trading involves risk. Only trade with money you can afford to lose. These guides are educational and are not financial advice.
