Am I ready to size up?

A good week is the most common reason traders add contracts, and the worst one. Four checks on your own record. The answer is not yet, hold where you are, or one step up.

    Built in your browser from the numbers above. Nothing is uploaded, and the card carries your inputs with it — a result without its assumptions isn't worth passing on.

    The four checks, and why each one
    1. At least 30 trades at this size. Fewer than that and your win rate could be almost anything. A hot streak looks exactly like skill over ten trades.
    2. Rules followed on at least 90% of trades. If you break your rules at this size, a bigger size makes every break cost more. Fix that first.
    3. The bottom of your likely win-rate range is above break-even. That’s the point where your record shows a method that makes money, not just a good run.
    4. Your room still covers 10 full losses at one contract more, and one more contract is within the firm’s limit. Losing streaks don’t care that you just sized up.

    These numbers are our rule of thumb, written down so you can see them. If your own rules are stricter, use yours.

    Why only one step

    One contract more is a step you can undo. If your rules score drops or a losing run starts at the new size, go back down and run this check again after another 30 trades. Traders who jump from 2 contracts to 5 on a good week usually give it back faster than they made it.

    How it’s calculated
    rules followed = trades that followed every rule / trades break-even win rate = average loss / (average win + average loss) likely range = Wilson 95% interval on winners / trades full losses covered = room left / (risk per contract x contracts)

    What this can’t tell you
    • The future. A record that passes all four checks still describes the past.
    • Whether your numbers are honest. Leave out the bad trades and it will happily tell you to size up.
    • Your firm’s other rules. Daily loss limits, scaling plans and news rules can all cap your size too. Check them.

    Educational tool only. This is arithmetic on numbers you type in — it is not investment advice, it does not predict anything, and it has no opinion on what you should trade. Trading futures involves substantial risk of loss and most people who try it lose money. Past results, including your own, do not predict future results. Verify contract specifications with your broker and your account rules with your firm; both change.
