What Is a Worked Example of Pipette Definition?

Direct answer

A worked example of pipette definition is a fully numeric walkthrough that starts with a clear definition, states every assumption (such as pip size, instrument decimal places, and position size), and then applies that definition to convert a price move into pips and pipettes.

Because providers can quote prices differently, a “pipette” should be treated as a meaning that follows from the pricing convention used for that instrument, not as a universal physical unit. With that caution, you can still build a self-contained example that is easy to verify.

Mechanism and definition

Pip is a standard unit for measuring price movement in FX. For many currency pairs quoted with 4 or 5 decimals, a common convention is that:

• 1 pip = 0.0001 (for pairs quoted to 4 decimals)
• 1 pip = 0.00001 price change in a 5-decimal quote where the last digit is an extra decimal

Pipette is often described as a smaller fractional movement. A common convention in practice is:

• 1 pipette = 0.1 pip (so 10 pipettes = 1 pip)

A worked example needs to decide which of these conventions you assume, and then stick to them.

Worked example with explicit assumptions

Assumptions (state-and-hold for the calculation):

1. The instrument’s pip size is 0.0001 price units (so we use a 4-decimal-style pip convention).
2. The pipette size is 0.1 pip, meaning 1 pipette = 0.00001 price units.
3. A hypothetical long position is held, but we only compute conversion of price movement to pipettes (not profit).
4. No spreads, commissions, or slippage are included.

Scenario:

• Entry price = 1.23450
• Exit price = 1.23475
• Price change = 1.23475 − 1.23450 = 0.00025

Step 1: Convert price change to pips

• 1 pip = 0.0001
• pips moved = 0.00025 ÷ 0.0001 = 2.5 pips

Step 2: Convert pips to pipettes

• 1 pipette = 0.1 pip
• pipettes moved = 2.5 ÷ 0.1 = 25 pipettes

Check:

• 25 pipettes × 0.00001 per pipette = 0.00025, which matches the price change.

This is a worked example of pipette definition because it shows exactly how the definition (pipette = 0.1 pip, and pip = 0.0001 here) produces a numeric conversion.

Two “both ways” comparisons (stable mechanics vs variable quoting)

• If the same price change is evaluated under a different decimal convention, the numeric pip/pipette counts can change even when the price move is identical. The stable part is the arithmetic once the unit size is defined.
• If a provider defines pipette differently (for example, tying it to the smallest quoted price increment), the definition you must use is the one implied by that quoting method.

Limitations and risks (material failure modes)

1. Pip vs pipette confusion: If you treat 1 pipette as 1 pip, your conversion factor becomes 10× wrong. In the example above, you would report 2.5 instead of 25.
2. Instrument-specific decimals: Some FX quotes use different decimal formatting. If pip size is assumed incorrectly, pip/pipette counts won’t match the intended convention.
3. Provider-dependent costing: Even though the worked example above excludes costs, real-world outcomes can differ due to spread, commission, and execution effects. Pip/pipette conversion alone does not predict net results.
4. Jurisdiction and contract differences: The way pip-related measures map to money can vary across contracts and jurisdictions. This worked example demonstrates unit conversion, not payout.

Verification and next question

To independently verify a pipette definition worked example, repeat the same steps with the same assumptions: compute the price change, divide by the assumed pip size to get pips, then apply the assumed pipette fraction (such as 0.1 pip) to get pipettes. If your pipette count differs, the mismatch is usually due to a different pip size or pipette fraction implied by the instrument’s quoting convention.

A useful next question is: What pip size and pipette fraction are implied by the specific quotation format you are using (number of decimals and the smallest price increment)?
