Pips, Lots, and Position Sizing

Pips, Lots, and Calculating Position Size

Before you place a single trade, you need to understand three foundational concepts: pips, lots, and position sizing. These are the building blocks of forex risk management, and getting them right will protect your trading capital from the very beginning.

A pip (percentage in point) is the smallest standard price movement in the forex market. For most currency pairs, a pip is 0.0001 — the fourth decimal place. For pairs involving the Japanese yen, a pip is 0.01 — the second decimal place.

For example, if EUR/USD moves from 1.08500 to 1.08560, it has moved 6 pips. Understanding pips is essential because they are the unit of measurement for gains and losses in forex trading.

What Is a Lot?

A lot is the standardised unit of measurement for trade size in forex. There are three common lot sizes:

• Standard Lot — 100,000 units of the base currency. Each pip is worth approximately $10.
• Mini Lot — 10,000 units. Each pip is worth approximately $1.
• Micro Lot — 1,000 units. Each pip is worth approximately $0.10.

Most retail traders start with micro or mini lots to limit their risk exposure while they are still learning.

Calculating Position Size

Proper position sizing is the cornerstone of risk management. The general rule followed by professional traders is to risk no more than 1–2% of your account balance on any single trade. Here is the formula:

Position Size = (Account Balance × Risk %) ÷ (Stop Loss in Pips × Pip Value)

Suppose you have a $1,000 account and want to risk 1% per trade ($10) with a 20-pip stop loss, and you are trading EUR/USD with a micro lot (pip value = $0.10). The calculation would be: $10 ÷ (20 × $0.10) = $10 ÷ $2 = 5 micro lots.

Why Position Sizing Matters

Ignoring position sizing is one of the most common mistakes new traders make. Without proper sizing, a single losing trade can wipe out a significant portion of your account. By capping risk at 1–2% per trade, even a string of 10 consecutive losses would only cost you 10–20% of your capital — giving you plenty of room to recover.

Summary

You now understand pips, lots, and how to calculate your position size. In the next lesson, we will explore the different types of forex orders and how to enter and exit the market correctly.
