Turn a quote into a sensible position.

In EUR/USD, EUR is the base currency and USD is the quote currency. A rate of 1.08480 says that one euro costs 1.08480 US dollars. The slash is doing real work: the quote has units of USD per EUR. [1][4]

Keep those units beside every conversion rate. If your answer is meant to be pounds but the calculation leaves dollars, the conversion is unfinished. This habit catches the most common multiply-versus-divide error before it reaches an order ticket.

Traders use pips to compare price distance across currency pairs. For many pairs, one conventional pip is 0.0001. For many pairs with JPY as the quote currency, it is 0.01. A smaller final digit is often called a pipette. The CFTC glossary describes a pip as the smallest price unit, while retail platforms separately expose points and minimum ticks—so always state the convention you are using. [2][3][4]

In common retail spot-FX-style specifications, one standard lot represents 100,000 units of the base currency. A mini lot is 10,000 and a micro lot is 1,000. That is a convention, not a law of nature. MetaTrader shows contract size, minimum volume and volume step as properties set for each symbol by the broker.[3][4][9]

First calculate how much one pip is worth in the pair's quote currency. Then, only if needed, convert that cash amount into the account currency. Separating the two steps makes the arithmetic much easier to audit.

Cross-currency pip value changes when the conversion rate changes. For an order, use a current rate and the platform's own tick-value estimate. The WickAtlas calculator keeps both stages visible so you can compare them.

A 12,700-unit EUR/USD position controls EUR 12,700. At 1.08480, that is USD 13,776.96 of quote-currency notional. If GBP/USD is 1.2700, the same exposure is about GBP 10,848. The position can be larger than the account because it is leveraged.

The leverage available on the account is a ceiling in the broker's rules. Effective leverage tells you how much exposure you are actually using. They are not the same. The FCA currently requires UK retail CFD leverage limits between 30:1 and 2:1, depending on the underlying asset; jurisdiction, client status and product matter. [7][8]

For MetaTrader's standard Forex calculation mode, the basic starting formula is lots × contract size ÷ leverage in the symbol's margin currency, followed by conversion if needed. Brokers can apply different modes, symbol margin rates, tiers and hedged-position rules, so the platform estimate is the final operational check. [4][5]

Decide the maximum cash loss for the idea. Put the stop where the trade thesis is invalidated, measure the distance, then calculate the units that fit both facts. If the broker's volume step cannot represent the answer exactly, round down and recalculate.

1. 01
   Set the cash-risk capGBP 5,000 × 0.5% = GBP 25

   The example is allowed to lose £25 before costs and slippage.

2. 02
   Measure the stop(1.08480 − 1.08230) ÷ 0.0001 = 25 pips

   The price difference is 0.00250.

3. 03
   Convert one USD into GBP1 ÷ 1.2700 = 0.7874 GBP per USD

   GBP/USD is quoted as USD per GBP, so invert it for GBP per USD.

4. 04
   Find pip value per base unit0.0001 USD × 0.7874 = GBP 0.00007874 per pip

   This is the account-currency value of one pip for one EUR unit.

5. 05
   Calculate the unitsGBP 25 ÷ (25 × GBP 0.00007874) = 12,700 EUR

   At these exact inputs, each pip is worth £1 and 25 pips is £25.

6. 06
   Translate and check12,700 ÷ 100,000 = 0.127 lot

   If the volume step is 0.01 lot, 0.12 is the conservative executable size; recalculate the risk after rounding.

1. 01
   Set the cash-risk capUSD 10,000 × 0.5% = USD 50

   The same risk percentage produces a $50 allowance.

2. 02
   Measure the JPY stop(148.350 − 148.100) ÷ 0.01 = 25 pips

   A 0.250 price change is 25 pips, not 2,500.

3. 03
   Convert a JPY pip into USD0.01 JPY ÷ 148.350 JPY per USD = USD 0.000067408 per unit

   Dividing cancels JPY and leaves USD.

4. 04
   Calculate the unitsUSD 50 ÷ (25 × USD 0.000067408) = 29,670 USD

   The theoretical result is 0.2967 of a 100,000-unit lot.

5. 05
   Respect the volume stepround down to 0.29 lot = 29,000 USD

   At 0.29 lot, one pip is about $1.9548 and 25 pips is about $48.87.

6. 06
   Check the alternative0.30 lot × 25 pips ≈ USD 50.56

   Rounding up breaches the $50 cap before costs, so 0.29 is the safer step.

The bid–ask spread is an inherent trading cost. A dealer may also charge commission, and holding a position can add financing or swap. Costs can turn a small gross profit into a net loss, so compare them in the account currency and for the holding time you actually expect. [1][3][4][6]

1. 01
   Open the symbol specification.

   Record contract size, volume step, pip or tick convention, profit currency, margin mode and swap.

2. 02
   Write down the account currency and current equity.

   Those decide the unit in which the risk limit and final pip value must be expressed.

3. 03
   Mark the entry and invalidation.

   The stop belongs where the setup is wrong, not where a preferred lot size looks comfortable.

4. 04
   Measure the stop in pips.

   Show the subtraction and divide by the pair's stated pip size.

5. 05
   Choose the maximum cash risk.

   Apply the planned percentage to current equity and consider total portfolio exposure.

6. 06
   Calculate account-currency pip value per unit.

   Use the quote currency first, then a clearly labelled conversion rate.

7. 07
   Calculate units and round down.

   Convert the result to lots only after the unit calculation, then obey the permitted volume step.

8. 08
   Add costs and check margin.

   Make sure the total planned loss remains acceptable and the account retains sensible free margin.

9. 09
   Preview it on demo and read the ticket back.

   Pair, direction, units, entry type, stop, target and expiry should all match the written plan.
