Lot Sizes: How Much Are You Trading?
Standard, mini, micro. The difference between $10/pip and $0.10/pip.
Researched and written by Laurent What Is a Lot?
In forex, you don't buy "1 euro" or "50 dollars." You trade in standardized quantities called lots. A lot defines how many units of the base currency you are trading.
| Lot Type | Units | Pip Value (USD pairs) | Example |
|---|---|---|---|
| Standard | 100,000 | $10/pip | Buy 1.00 lot EUR/USD = buy 100,000 euros |
| Mini | 10,000 | $1/pip | Buy 0.10 lot EUR/USD = buy 10,000 euros |
| Micro | 1,000 | $0.10/pip | Buy 0.01 lot EUR/USD = buy 1,000 euros |
| Nano | 100 | $0.01/pip | Buy 0.001 lot (some brokers only) |
On most trading platforms, you'll enter lot sizes as decimals:
- 1.00 = 1 standard lot
- 0.10 = 1 mini lot
- 0.01 = 1 micro lot
- 0.50 = 5 mini lots (or half a standard lot)
Why Lot Size Matters
Let's say EUR/USD moves 50 pips in your favor. Here's what that's worth at different lot sizes:
| Lot Size | 50 Pips = Profit | 50 Pips = Loss |
|---|---|---|
| 0.01 (micro) | $5 | -$5 |
| 0.10 (mini) | $50 | -$50 |
| 1.00 (standard) | $500 | -$500 |
| 10.00 (10 standard) | $5,000 | -$5,000 |
Same market move. Wildly different outcomes. This is why lot size is one of the most important decisions you make on every trade. It's not about finding the perfect entry; it's about sizing your trade appropriately for your account.
What Size Should Beginners Use?
Micro lots (0.01). Period.
With a micro lot, a 50-pip loss costs you $5. With a $500 demo account (or a small live account later), that's 1% of your balance. You can make mistakes, learn from them, and not blow your account in the process.
The temptation is to trade bigger. "Micro lots are boring, I only make $3 per trade." That's the point. You're not here to make money yet. You're here to learn. When you have a proven strategy and consistent results over 50-100+ trades on micro lots, THEN you consider increasing size.
Fractional Lots
Most modern brokers let you trade in fractional lots with fine precision. You're not limited to exactly 0.01 or 0.10. You can trade 0.03 lots, 0.07 lots, 0.15 lots, etc.
This flexibility is important for proper position sizing. In Level 7 (The Strategist), we'll teach you exactly how to calculate the right lot size for every trade based on your account size, risk tolerance, and stop-loss distance. For now, just know that the option exists.
The Connection to Leverage
You might wonder: "If a standard lot is 100,000 euros, do I need $100,000 in my account?" No. This is where leverage comes in.
Leverage is borrowed capital from your broker. With 1:100 leverage, you can control a $100,000 position using just $1,000 of your own money. The broker effectively lends you the other $99,000 for the duration of the trade.
This sounds great until you realize leverage multiplies losses just as much as profits. A 1% adverse move on a $100,000 position is a $1,000 loss, which wipes out your entire $1,000 margin. This is why regulators cap retail leverage:
| Regulator | Region | Max retail leverage (majors) |
|---|---|---|
| ESMA | EU | 1:30 |
| FCA | UK | 1:30 |
| ASIC | Australia | 1:30 |
| NFA | USA | 1:50 |
| FSA | Japan | 1:25 |
| None (SVG has no forex regulation) | St. Vincent and the Grenadines | up to 1:1000+ (unregulated) |
| VFSC (licensed, light-touch oversight) | Vanuatu | up to 1:1000+ |
We'll cover leverage mechanics in detail in Level 2 (lessons 2-8 through 2-10). For now, the takeaway is simple: lot size determines your profit/loss per pip, and beginners should use micro lots.
Key Takeaways
- • A standard lot is 100,000 units of the base currency.
- • A mini lot is 10,000 units. A micro lot is 1,000 units.
- • Most beginners should use micro lots to keep risk small while learning.
- • Your lot size directly determines how much each pip is worth in your account.
