What is a lot in forex?

The unit no one explains clearly

When someone says they "bought EUR/USD," the next question should be: how much? In forex, that answer is always given in lots — the standardized unit of trade size.

A lot isn't slang. It's not approximate. It's a contract-size definition that every broker, platform, and trader uses to measure position size.

The four lot sizes

Here's the breakdown:

• Standard lot: 100,000 units of the base currency
• Mini lot: 10,000 units
• Micro lot: 1,000 units
• Nano lot: 100 units

If you open 1 standard lot of EUR/USD, you're controlling €100,000 worth of exposure. If you open 1 micro lot, you're controlling €1,000.

Most retail traders in the Philippines start with micro or nano lots. That's not a limitation — it's risk management.

Why lot size is the first real decision you make

Lot size is what turns abstract price movement into actual money. Let's say EUR/USD moves 10 pips in your favor.

• On a nano lot (100 units), that's roughly ₱5.
• On a micro lot (1,000 units), that's roughly ₱50.
• On a mini lot (10,000 units), that's roughly ₱500.
• On a standard lot (100,000 units), that's roughly ₱5,000.

Same chart. Same direction. Same 10 pips. The only variable is the size you chose.

A real scenario: OFW remittance hedging

Imagine a kababayan working in Dubai expects to send home $2,000 next month. Right now USD/PHP is at 56.50, so that's ₱113,000. But if the peso strengthens to 55.00 by next month, the same $2,000 becomes ₱110,000 — a ₱3,000 loss in purchasing power.

If this person wanted to hedge that exposure using forex, they'd need to think in lot sizes. A micro lot of USD/PHP (1,000 units) represents $1,000 of exposure. To hedge $2,000, they'd use 2 micro lots — or 0.02 standard lots.

This is not a recommendation to hedge remittances via retail forex. It's an illustration: lot size is the bridge between abstract currency units and real-world money.

Lot size is leverage's twin

You'll hear a lot about leverage soon (we'll cover it properly in a future post). But here's the preview: leverage allows you to control a large lot with a small deposit. A standard lot might require only $1,000 in margin at 100:1 leverage.

That sounds like a gift. It's actually a test. If you don't understand lot size, leverage becomes a way to lose money faster than you thought possible.

What to remember

Lot size is not complicated. It's just a unit. But it's the unit that matters most when a trade goes live, because it's the multiplier on every pip of movement — in both directions.
