A structured foundation in how the currency market actually works — written for people who want to understand it, not just be excited by it. Free, in order, no prior knowledge assumed.
The foreign exchange market is where one currency is exchanged for another. Every quote is a relationship between two economies, not the price of a single thing. When you see EUR/USD at 1.0850, that means one euro costs 1.0850 US dollars. Buying the pair is a bet the euro strengthens against the dollar; selling it is the reverse. There is no “up” in isolation — one side always rises as the other falls.
It is the largest financial market in the world. The Bank for International Settlements measured average daily turnover at $9.6 trillion in April 2025, up 28% from 2022, with the US dollar on one side of 89.2% of all trades. It trades continuously from Sunday evening to Friday evening, moving between the Sydney, Tokyo, London and New York sessions.
Scale is not the same as opportunity, though. That liquidity is dominated by banks, institutions and algorithms. As a retail trader you are a very small participant in a market where the other side is often better informed and better capitalised than you. That is the honest framing this course is built on.
Retail forex trading carries a high risk of loss, and a substantial majority of retail accounts lose money over time. Nothing on this page is advice, and none of it makes trading safe. Treat this as an education in a difficult activity, not an invitation to start one.
Work through them sequentially. Each one assumes the one before it. Skipping to strategy is the single most common way beginners waste their first year.
Currency pairs and how quotes are constructed. Base and quote currency. Majors, minors and exotics. Bid, ask and the spread. What a pip is and what one is worth in your account currency. Lot sizes — standard, mini and micro — and how they translate into real money per pip.
The three ways trading costs you money: spread, commission and overnight swap. Then leverage — what a 1:30 or 1:500 ratio actually means, how margin is calculated, what a margin call is, and how stop-outs work. Most beginner account failures are leverage failures rather than analysis failures.
Market, limit and stop orders. Stop-loss and take-profit placement. Slippage and why your fill is not always your price. Gaps over weekends and around major news. Why “I’ll close it manually” is not a risk plan.
The core module. Fixed-percentage risk per trade. Calculating position size from stop distance rather than guessing lots. Risk-to-reward ratios and the win rate each one requires to break even. Drawdown mathematics — why a 50% loss needs a 100% gain to recover. Correlation risk across pairs.
Reading price action and market structure. Support, resistance and trend. What indicators actually measure and their limitations. On the fundamental side: interest rates, inflation, employment data and central bank policy — the forces that set currency values over anything longer than a session.
Why traders break their own rules, and the specific conditions that cause it: revenge trading after a loss, over-sizing after a win, moving stops, abandoning a system during a normal losing streak. Building a written trading plan and a journal that produces genuine feedback rather than a scorecard.
A quick reference. Each of these is covered in depth in the module it belongs to.
| Term | What it means in practice |
|---|---|
| Pip | The standard smallest price increment for a pair — 0.0001 for most, 0.01 for JPY pairs. Its cash value depends entirely on your position size, which is why pips alone tell you nothing about risk. |
| Spread | The gap between the buy and sell price. You pay it on entry, every time. A trade starts marginally negative and has to cover this before it is breakeven. |
| Leverage | Borrowed exposure. 1:100 leverage lets $1,000 control $100,000 of currency. It multiplies gains and losses identically — it is not a feature that helps you, it is a risk multiplier you must manage. |
| Margin | The deposit your broker holds against an open position. Fall below the required level and positions are closed automatically, often at the worst possible moment. |
| Swap / rollover | Interest credited or debited for holding a position overnight, based on the rate differential between the two currencies. Can quietly dominate the economics of a long-held trade. |
| Lot | Position size. One standard lot is 100,000 units of the base currency; a mini lot is 10,000; a micro lot is 1,000. Choosing this correctly is risk management. |
| Drawdown | The decline from a peak in account equity. The number that actually tells you whether a strategy is survivable, and the one most people ignore in favour of returns. |
| Slippage | The difference between the price you expected and the price you got. Widens in fast markets and around news — the moments you are most likely to need an exit. |
This single calculation is more valuable than any indicator you will ever add to a chart.
Account balance: $5,000
Risk per trade: 1% = $50
Pair: EUR/USD
Entry: 1.0850
Stop-loss: 1.0820 (30 pips away)
The question is not “how many lots feel right” — it is “what size makes a 30-pip loss cost exactly $50?”
On EUR/USD, one standard lot is worth roughly $10 per pip. A 30-pip stop on one standard lot would therefore cost about $300 — six times the intended risk.
Position size = risk ÷ (stop in pips × pip value)
= $50 ÷ (30 × $10) = 0.17 lots
So the correct size is roughly 0.17 lots, not one. Take this trade at one lot and eight consecutive losses — an entirely ordinary run — would remove nearly half the account.
The practical mechanics: placing your first order, reading a statement, building a written trading plan.
