How a Forex Trade Actually Works
From clicking "buy" to seeing profit or loss. Step by step.
Researched and written by Laurent The Life of a Trade: 6 Steps
Let's follow a trade from beginning to end. You want to buy EUR/USD because you think the euro will rise.
Step 1: You Decide to Trade
You've analyzed the market (we'll teach you how in later levels). You believe EUR/USD will rise from 1.0850 to at least 1.0900. You decide to buy.
Step 2: You Open the Order
On your trading platform (MT4, MT5, or another), you:
- Select the pair: EUR/USD
- Choose the direction: Buy
- Set the lot size: 0.10 (1 mini lot)
- Set a stop-loss: 1.0820 (30 pips below entry, to limit your loss)
- Set a take-profit: 1.0900 (50 pips above entry, your target)
- Click "Buy"
Step 3: The Order Is Executed
Your broker receives the order. Depending on the broker type:
- ECN/STP: Your order is sent to a liquidity provider (usually a bank) who fills it at the best available price.
- Market maker: The broker fills the order internally from its own inventory.
In either case, this happens in milliseconds. You see a confirmation: "Buy 0.10 EUR/USD at 1.08502."
Notice the price is 1.08502, not exactly 1.0850. This small difference can happen due to:
- The bid-ask spread (you buy at the ask price)
- Slippage (price moved slightly between your click and execution)
Step 4: The Trade Is Open
Your position is now live. On your platform's "Trade" or "Terminal" panel, you see:
- Symbol: EUR/USD
- Type: Buy
- Volume: 0.10
- Entry price: 1.08502
- Current price: updating in real time
- Stop-loss: 1.08200
- Take-profit: 1.09000
- Profit/Loss: fluctuating (starts slightly negative due to the spread)
Every time the EUR/USD price ticks up, your P/L increases. Every time it ticks down, your P/L decreases. With a mini lot, each pip is worth approximately $1.
Step 5: The Trade Closes
Your trade will close in one of three ways:
A) Take-profit hit: Price reaches 1.0900. Your trade automatically closes. You made 50 pips = approximately $50.
B) Stop-loss hit: Price drops to 1.0820. Your trade automatically closes. You lost 30 pips = approximately $30.
C) Manual close: You decide to close the trade yourself before either level is hit. Maybe price is at 1.0875 (+25 pips) and you want to lock in the profit.
Step 6: Post-Trade
The trade moves from your "Open Trades" tab to your "Account History." You can see the full details: entry, exit, duration, profit/loss, swap (if held overnight), and commission (if applicable).
This information goes into your trading journal (which we'll set up in Level 3).
What Happens Behind the Scenes
When you buy EUR/USD, you don't actually receive 10,000 euros in an account somewhere. Forex trading is based on contracts for difference (CFDs) in most retail contexts. You're trading the price difference, not exchanging physical currency.
Your broker keeps track of your entry price and current price. When you close the trade, the difference (profit or loss) is settled in your account currency. No actual euros change hands at the retail level.
The Emotional Side
Here's what the textbooks don't tell you: watching an open trade is an emotional experience. You'll feel:
- Anxiety when the trade goes against you ("Should I close it?")
- Excitement when it moves in your favor ("Should I add more?")
- Impatience when it goes sideways ("When will it MOVE?")
We'll address the psychology of trading in Level 8 (The Stoic). For now, just be aware that these feelings are universal and normal.
Key Takeaways
- • A trade starts when you click buy/sell and ends when you close the position.
- • Your order is routed through your broker to a liquidity provider.
- • While a trade is open, your P/L changes tick by tick in real time.
- • You close a trade manually, or it closes automatically via stop-loss or take-profit.
