What Is a Pip in Forex? Lots, Pips and Position Size Explained Simply

The forex market turns over more than $7.5 trillion every single trading day, according to the Bank for International Settlements' 2022 triennial survey. Nigerian retail traders are a growing fraction of that figure, drawn in by the naira's persistent volatility and the widening gap between the CBN's official rate and parallel-market quotations. Yet the basics trip up most beginners: what exactly is a pip, what is a lot, and why does position size determine whether you survive or blow an account? This guide answers all three questions in plain English.

What Is a Pip in Forex?

A pip, short for "percentage in point" (or "price interest point"), is the smallest standardised price movement in a currency pair. For most pairs quoted to four decimal places, one pip equals 0.0001. On USD/NGN, for example, a move from 1,580.0000 to 1,580.0100 represents one pip.

The exception is the Japanese yen. Yen pairs are quoted to only two decimal places, so one pip equals 0.01. A move in EUR/JPY from 160.50 to 160.51 is one pip.

Many retail platforms now quote to a fifth decimal place, called a pipette or fractional pip. A pipette equals one-tenth of a standard pip, giving traders and algorithms greater precision on order execution.

Why does the pip matter?

Because the pip is the unit in which profit and loss is counted. If you are long EUR/USD and the pair moves 50 pips in your favour, your gain in dollar terms depends entirely on how large your position is, which brings us to lot sizes.

What Is a Lot in Forex, and How Do Lot Sizes Affect Risk?

A lot defines the volume of currency you are trading. The forex industry standardised lot sizes as follows:

• Standard lot: 100,000 units of the base currency
• Mini lot: 10,000 units
• Micro lot: 1,000 units
• Nano lot: 100 units (offered by some brokers)

On EUR/USD, one standard lot means you are controlling €100,000 worth of euros against the dollar. One mini lot controls €10,000.

Pip value by lot size (EUR/USD as an example)

For most USD-quoted pairs, the pip value formula simplifies neatly:

Pip value = (Pip size / Exchange rate) x Lot size

On EUR/USD, the exchange rate in the denominator is approximately 1.00 when the pair trades near parity, so:

• Standard lot: 0.0001 x 100,000 = $10 per pip
• Mini lot: 0.0001 x 10,000 = $1 per pip
• Micro lot: 0.0001 x 1,000 = $0.10 per pip

Now convert that to naira. At the CBN's published indicative rate of roughly ₦1,580 per dollar as of early June 2026, a single pip on a standard EUR/USD lot is worth approximately ₦15,800. On a 50-pip move that is ₦790,000 gained or lost. The numbers clarify immediately why position sizing is not optional knowledge.

How Do You Calculate Position Size Correctly?

Position sizing is the process of choosing a lot size that keeps your risk within a defined percentage of your account. Professional traders rarely risk more than 1–2% of capital on any single trade. The calculation has three inputs: account size, risk percentage, and stop-loss distance in pips.

The formula:

Position size (in lots) = (Account risk in $) / (Stop-loss in pips x Pip value per lot)

Work through a practical example. Suppose you have a $2,000 trading account, you risk 1% per trade ($20), and your analysis calls for a 25-pip stop-loss on GBP/USD.

• Pip value on GBP/USD standard lot: approximately $10
• Position size = $20 / (25 pips x $10) = $20 / $250 = 0.08 lots

You would open a micro-to-mini position of roughly 0.08 lots, not a standard lot. On many platforms this is directly selectable. The calculation keeps your worst-case loss at $20 regardless of whether the market moves sharply against you.

In naira terms, $20 at ₦1,580/$ equals ₦31,600. That is the maximum you have pre-agreed to lose before the stop order triggers. Framing it in naira first, then converting, often makes the abstract feel concrete.

Cross Rates and the NGN Variable

Most Nigerian traders access forex through pairs such as EUR/USD, GBP/USD, or USD/JPY rather than through NGN-denominated crosses. The naira is not freely convertible, and the CBN's foreign exchange framework — most recently articulated through its 2023 unification directive — governs who may access forex officially and at what rate.

This matters for position sizing because your account is funded in dollars or euros, yet your living expenses are denominated in naira. A $500 drawdown feels very different at ₦800 per dollar (the pre-unification official rate) versus ₦1,580 per dollar (the post-unification rate). The NBS has tracked the naira's depreciation in its Consumer Price Index releases; headline inflation reached 33.69% year-on-year in April 2025, reflecting the cumulative pass-through of FX weakness. Traders who ignored this context took far larger real losses in naira than their dollar P&L statements suggested.

Common Pip Mistakes Nigerian Traders Make

Confusing pips with pipettes. A platform quoting EUR/USD at 1.08423 is using five decimal places. The pip is still the fourth decimal (0.0001), not the fifth. If you misread a 3-pipette move as 3 pips, your position-size calculation is inflated tenfold.

Using standard lots with micro accounts. At $10 per pip, a standard lot on a $500 account means a single 50-pip adverse move wipes the account entirely. Regulatory bodies in other jurisdictions cap retail leverage specifically to prevent this outcome. Nigerian traders accessing offshore platforms should check the leverage terms carefully before depositing.

Ignoring spread in the pip count. Brokers earn revenue through the bid-ask spread, typically 1–3 pips on major pairs and considerably wider on exotic pairs that include the naira. A 20-pip target is effectively 17–19 pips after spread. Model this into your risk-reward calculations from the outset.

Forgetting to recalculate after account growth or drawdown. Position size must be recalculated for each trade based on the current account balance, not the starting balance. A static lot size locks in either over-risking after losses or under-utilising capital after gains.

A Quick Reference

| Lot type | Units | Pip value (USD/USD pair) | |----------|-------|--------------------------| | Standard | 100,000 | $10.00 | | Mini | 10,000 | $1.00 | | Micro | 1,000 | $0.10 | | Nano | 100 | $0.01 |

Pip values are approximate and vary with the exchange rate of the pair being traded.
