    WTI Position Size on a Funded Account

    A beginner's guide: how many lots can one stop-out afford?

    Lots = (daily starting equity x risk %) / (stop distance x multiplier), rounded down to 0.01. The calculator then compares the amount at risk with the daily loss allowance left. The prices loaded are round example numbers, not market prices: enter your own entry and stop.

    How to size a WTI trade: 4 steps

    1. Pick the dollars you risk

      equity x risk %

      $100,000 x 0.5% = $500

      Your stop-out loss, decided before the trade.

    2. Measure the stop distance

      |entry - stop|

      70.00 - 69.50 = 0.50

      Dollars per barrel between entry and stop.

    3. Price one lot's loss

      distance x 1,000

      0.50 x 1,000 = $500

      One lot is 1,000 barrels, so every $1 move is $1,000.

    4. Divide

      risk / loss per lot

      $500 / $500 = 1.00 lot

      Round down to 0.01 so the stop never costs more than you chose.

    Hypothetical round numbers, not market prices. Try it below: the calculator starts with the same example.

    The prices loaded here are round example numbers, not current market prices. Replace them with your own entry, stop and target. USD account, USD-quoted instruments.

    Lowers the daily allowance left. Leave empty at the start of the day.

    Limits and how they are measured differ by programme (FTMO's 1-Step has a 3% daily limit, for example). The presets are the 2-step limits from each firm's published rules: pick Custom Account for any other.

    Instrument and multiplier

    Contract sizes differ between brokers (gold is often 100 oz, oil 1,000 barrels or 100). Check yours, then use Custom if it differs.

    %

    Slider range 0.25% to 2% of daily starting equity. This tool shows the consequence of a number; it does not recommend one.

    Recommended lot size

    1.00lots

    Rounded down to 0.01. If the stop is hit you lose about $500.00. Exact figure: 1.0000 lots.

    SAFE

    A stop-out would use 10.0% of the $5,000.00 daily allowance that is left.

    Thresholds: up to 30% of the allowance is safe, up to 60% is a warning, above 60% is danger.

    For your account: if this stop is hit you lose about $500.00 and keep about $4,500.00 of today's allowance and $9,500.00 overall. Check these before you enter, not after.

    Beginner's glossary Lot, equity, risk %, stop loss, daily limit in one line each.
    Lot:
    The trade size unit. For WTI here, 1 lot = 1,000 barrels. 0.10 lot = 100 barrels.
    Equity:
    Your account value at the start of the trading day, including open profit or loss.
    Risk %:
    The share of equity you accept losing if the stop is hit. The calculator shows the consequence of a number; it does not recommend one.
    Stop loss:
    The price where the trade closes at a loss. A wider stop means fewer lots for the same risk.
    Daily loss limit:
    The most a firm lets you lose in a day. The calculator shows what share of it one stop-out would use.
    Common beginner mistakes Five ways the number comes out wrong.
    • Using last week's balance instead of today's starting equity.
    • Wrong contract size: some brokers use 100 barrels per lot, not 1,000. Check yours and use Custom.
    • Forgetting spread and slippage: oil can gap, especially around the weekly EIA report, so the real loss can exceed the planned one.
    • Moving the stop wider after entry without cutting the size.
    • Sizing for one trade while ignoring the losses already taken today.
    Wider stop, fewer lots Same $500 risk: a 1.00 stop means 0.50 lot, a 0.25 stop means 2.00.

    Lots = $500 / (distance x 1,000). Distance 1.00 gives 0.50 lot. Distance 0.25 gives 2.00 lots. The money at risk stays the same; the size changes. Hypothetical numbers.

    Worked example $100,000 account, 0.5% risk, 0.50 stop: 1.00 lot.

    Hypothetical numbers, not market prices. Risk = $100,000 x 0.5% = $500. Stop distance = 0.50. At 1,000 barrels per lot: 500 / (0.50 x 1,000) = 1.00 lot. Against a 5% daily limit ($5,000), one stop-out uses 10% of the allowance.

    Around the EIA report Oil can jump on Wednesdays; some firms restrict trading then.

    The EIA publishes its weekly report on Wednesdays after 10:30 a.m. ET. Check whether your firm restricts it for your account type before you hold a position through it: see the Wednesday checklist and the news trading rules.

    What it does not model Spread, slippage, gaps, commission and swaps.

    A real loss can exceed the figure shown. Firms measure the daily and overall loss in their own way (balance or equity, static or trailing): use the drawdown calculator for a firm's published formula. Prop accounts are simulated and evaluation fees can be lost. Nothing here promises a pass or a profit.

    Frequently asked questions

    How many lots of WTI can I trade on a funded account?

    It depends on your risk per trade and your stop distance, not on the account size alone. Lots = (daily starting equity x risk %) / (stop distance x contract multiplier). The calculator also shows how much of the day's loss allowance one stop-out would use.

    What is the contract size for WTI?

    The calculator uses 1 lot = 1,000 barrels. Some brokers use 100 barrels per lot, so check your broker's contract specification and use the Custom option if it differs.

    Does it include spread and slippage?

    No. Oil can gap and slip, especially around the weekly EIA report, so a real loss can exceed the figure shown. Treat the result as a planning figure.

    Can I trade WTI around the EIA report on a funded account?

    Rules differ by firm and account type. FTMO's FAQ names Crude Oil Inventories among restricted events on a Standard FTMO Account. See the Wednesday checklist and check your firm's calendar.
