What you actually trade in Forex/CFDs

8 分钟阅读Intro

Open MT4 / TradingView and you see EUR/USD at 1.0850 — is that the market price?

Not quite. What you see is the mirror your broker chooses to show you. The real interbank market is out of your reach. This lesson clears up three things: what you actually trade, who's making the money, and why most retail traders lose to spread alone.

1. Forex / CFD / Spot — stop conflating them

| You say | What it actually is | |---|---| | "I trade forex" | Most often it's a CFD, not real currency exchange | | "I bought dollars" | Real spot deals; that's the interbank market — you don't touch it | | "I trade the spread" | You're betting against your broker on EUR/USD direction. No currency ever changes hands. |

CFD = Contract For Difference. You and the broker sign: I bet price goes up, you bet down. At settlement, whoever's right is paid the difference. No dollars are bought.

This means:

  • ✅ High leverage (100:1+), small accounts can play
  • ✅ Easy two-way (shorting is just another contract)
  • ❌ Your broker is both your counterparty and your service provider — conflict of interest is structural
  • ❌ Spread + overnight financing = the more you trade, the more it makes

2. The 3 layers of price

What you see

EUR/USD 1.0850

"I thought the price was just 1.0850"

What's happening

Bid 1.0849 / Ask 1.0851

Spread = 2 pips — the broker pockets that

The real interbank quote might be 1.0850.3 / 1.0850.5, spread 0.2 pips

Every time you open a position → you're instantly down 2 pips (spread). You have to earn those 2 pips back before breaking even.

3. Leverage — retail's most dangerous tool

Leverage amplifies gains and losses equally.

01关键结论

Under 100:1 leverage, 1% price movement = 100% account movement. EUR/USD moving from 1.0850 to 1.0742 (down 1%) → your account is zero. A 1% daily move in EUR/USD is common — a single news headline does it.

💪 Try it: real numbers, real lot size

Account $10,000. You want to risk 1% to go long EUR/USD at 1.0850 with stop at 1.0820. If 1 pip = $10 per standard lot, what lot size?

🔍 Can you spot your own blind spot?

Lisa sees EUR/USD breaking 1.0850. Account $1000, she goes long 1 mini lot (10,000 units) at 100:1 leverage with no SL, planning to take profit at 1.0900 for 50 pips. Score her on 5 dimensions (0=bad / 1=average / 2=good):

Dimension 1
Is her position size reasonable relative to the account?
Dimension 2
Is her stop-loss setup professional?
Dimension 3
Does her risk per trade follow the 1-2% rule?
Dimension 4
Is her entry thesis strong enough and based on a setup, not emotion?
Dimension 5
Is her exit plan systematic?

🎯 Can you spot a fake breakout?

EUR/USD daily. You see the first 23 candles — a strong breakout above prior highs followed by 2 continuation bars. What happens next?

$1000 account, 100:1 leverage. Max lot size on EUR/USD? (1 lot = 100,000 units)

4. Who's on the other side

The money you make has to come from someone. Question is who.

  • A-Book brokers: route your orders to the interbank market, earn from spread and commission. Their interests align with yours (you win, they earn more).
  • B-Book brokers (a.k.a. dealing desks): your counterparty is the broker itself. You lose, they win. Most retail brokers are B-Book — because most retail traders lose long-term, B-Book is a steady business.

02关键结论

The first reason retail loses long-term isn't directional error. It's not realizing you start every trade already down the spread, and every oversized position amplifies the next mistake. Understand structure first, then talk about technical analysis.
