How to Calculate Lot Size for EURAUD
BY TIOmarkets
|March 31, 2026Calculating the correct lot size before entering a EURAUD trade is a foundational risk management step. Because EURAUD is quoted in Australian dollars, the pip value is denominated in AUD rather than USD, which means traders holding USD-based accounts need to apply a currency conversion to understand their actual risk exposure in their account currency.
This guide walks through the contract specifications, pip value calculation, margin requirements, and a practical position sizing method for EURAUD at TIOmarkets.
EURAUD Contract Specifications at TIOmarkets
The EURAUD instrument at TIOmarkets represents the exchange rate between the euro and the Australian dollar. One standard lot equals EUR 100,000, one mini lot equals EUR 10,000, and one micro lot equals EUR 1,000. The minimum trade size is 0.01 lots, which is EUR 1,000. The maximum lot size per trade is 20 lots across all account types.
EURAUD trades on MT4 and MT5. On MT5, the symbol is EURAUD. The MT4 symbol for EURAUD has not been confirmed from a TIOmarkets source page and should be verified inside the platform before trading. Trading is available Monday through Thursday from 00:00 to 24:00 server time, and Friday from 00:00 to 23:55. The market is closed on Saturday and Sunday.
Spreads on EURAUD are variable and will typically be higher than the minimum figures shown on the TIOmarkets website. Overnight swap rates apply and should be checked directly inside the MT4 or MT5 platform, as rates change and are not published in advance.
What Is the Pip Value for EURAUD?
For EURAUD, the pip is the fourth decimal place in the price. One pip equals 0.0001. Because the Australian dollar is the quote currency, each pip movement is worth AUD 10 per standard lot, AUD 1 per mini lot, and AUD 0.10 per micro lot.
For traders holding USD-denominated accounts, the AUD pip value must be converted to USD using the current AUD/USD exchange rate. The conversion is:
USD pip value = AUD pip value × AUD/USD rate
Using an illustrative AUD/USD rate of 0.6889:
- Standard lot: AUD 10 × 0.6889 = USD 6.89 per pip
- Mini lot (0.1): AUD 1 × 0.6889 = USD 0.69 per pip
- Micro lot (0.01): AUD 0.10 × 0.6889 = USD 0.069 per pip
These figures are illustrative only. Because AUD/USD fluctuates continuously, the USD equivalent of each pip will change with it. The pip value in AUD is always fixed at AUD 10 per standard lot for any AUD-quoted pair, but the USD conversion varies in real time. Traders using accounts in currencies other than USD should use the TIOmarkets Pip Value Calculator to obtain accurate figures for their account currency.
How to Calculate Margin for EURAUD
The margin requirement for EURAUD at TIOmarkets is 1%, which is standard for most major and minor currency pairs. Leverage is available up to unlimited on the Standard account, subject to change depending on market conditions and applicable regulatory requirements.
The margin formula for a forex position is:
Required margin = (Lot size × Contract size × Opening price) × Margin percentage
For a 1.0 lot EURAUD trade opened at an illustrative rate of 1.6759:
Required margin = (1 × 100,000 × 1.6759) × 0.01 = AUD 1,675.90
For a USD account, this AUD margin figure is converted to USD at the prevailing AUD/USD rate. At an illustrative AUD/USD of 0.6889:
USD margin = AUD 1,675.90 × 0.6889 = approximately USD 1,154.70
These figures are illustrative. Actual margin required will vary with the EURAUD price and the AUD/USD conversion rate at the time of trade entry. The TIOmarkets Margin Calculator will calculate the exact margin required in your account currency.
Position Sizing Formula for EURAUD
Position sizing connects your risk tolerance to the correct lot size for a given trade. The standard approach is to define the maximum monetary amount you are prepared to risk on a single trade, then back-calculate the lot size from that figure and your intended stop loss distance in pips.
Step 1: Define your risk amount
For example, a trader with a USD 10,000 account risking 1% per trade has a risk budget of USD 100.
Step 2: Determine your stop loss in pips
If the stop loss is placed 40 pips from the entry price, the stop loss distance is 40 pips.
Step 3: Calculate the required pip value
Required pip value = Risk amount / Stop loss distance = USD 100 / 40 = USD 2.50 per pip
Step 4: Convert the required USD pip value to AUD
Because EURAUD pip values are in AUD, divide the required USD pip value by the AUD/USD rate:
Required AUD pip value = USD 2.50 / 0.6889 = AUD 3.63
Step 5: Calculate lot size
Lot size = Required AUD pip value / AUD 10 (pip value per standard lot) = AUD 3.63 / AUD 10 = 0.363 lots
Round down to the nearest available increment — in this case, 0.36 lots.
This calculation assumes a USD account at an illustrative AUD/USD rate of 0.6889. For accounts in other base currencies, or for a faster and more accurate result, use the TIOmarkets Lot Size Calculator. Enter your account currency, the EURAUD pair, your risk amount, and your stop loss distance in pips to get the recommended lot size directly.
Using TIOmarkets Calculators for EURAUD
TIOmarkets provides four calculators at tiomarkets.com to support trade planning:
The Lot Size Calculator calculates the appropriate lot size based on your account currency, risk amount, and stop loss distance in pips. This is the most direct tool for the position sizing workflow described above.
The Pip Value Calculator shows the monetary value of one pip for a given lot size in your account currency. Use this to confirm pip value before entering a position.
The Margin Calculator shows the margin required to open a position at a given lot size. Use this to check that sufficient free margin is available before placing the trade.
The Profit Calculator estimates the profit or loss from a trade based on entry price, exit price, and lot size. Use this to assess the reward side of a trade alongside the risk calculation.
All four calculators support multiple account currencies and a broad range of instruments including EURAUD.
Trading Costs on EURAUD
Understanding the full cost of a EURAUD trade helps with accurate position sizing and expectancy calculations.
The spread on EURAUD is variable. It represents the difference between the bid and ask price at the time of execution and is the primary cost on Standard and VIP Black accounts. Spreads are typically higher than the minimum figures shown and will widen during periods of lower liquidity or higher volatility, such as around major news events.
On the Raw account, spreads start from 0.0 pips and a commission of USD 6 per round turn lot applies. This commission is charged in full when the position is opened and covers both the open and close of the trade. For non-USD base currency accounts, the commission is converted at the prevailing rate. On Standard and VIP Black accounts, there is no commission.
Overnight swap charges apply to positions held past the daily rollover. Swap rates for EURAUD should be checked inside the MT4 or MT5 platform, as they are not published in advance and change regularly.
Orders are executed at the best available market price, which may result in positive or negative slippage. Demo accounts often execute instantly and may not fully replicate live slippage conditions.
