Oversized Position

A trade bigger than you planned, riskier than your own max risk per trade, or far above your usual size. Usually paired with confidence or revenge. Limbix flags oversized positions automatically: each of the three checks below compares the trade with a number of your own.

How it's calculated#

$$\text{Oversized} = \left(q > q_{\text{plan}} \times k_{\text{plan}}\right) \;\vee\; \left(\text{risk} > \text{max risk}\right) \;\vee\; \left(q > \bar{q}_{30d} \times k_{\text{avg}}\right)$$

q

The trade's quantity.

q_plan

The Planned size you entered on the trade.

risk

The trade's risk amount: what it put at risk, worked out from its stop. See R-multiple.

max risk

Your Max risk per trade from Settings, as a currency amount.

q̄ 30d

Your average quantity over the previous 30 days.

k plan

A small allowance above your plan, so a rounding difference isn't flagged.

k avg

The multiple of your usual size that counts as far above it.

Any one of three checks flags the trade:

The risk amount comes from the trade's stop, as explained in R-multiple. A percentage limit is converted with your account size first. If a trade is in a different currency from your account, the risk check is skipped rather than guessed across an exchange rate. The limit today comes from Max risk per trade in Settings. Prop firm rules and check-in declarations don't yet carry a per-trade figure. See the risk limit chain.

Oversized Position sits in the Risk group of the mistake tracker: "Size and stops — what threatens the account." The full rule is on mistake detectors.

Worked example#

Your account is €50,000 and your Max risk per trade is 1%, so the limit is €500.

• Trade A. One contract with a stop that puts €650 at risk. €650 is above €500, so it is flagged.
• Trade B. You planned 2 contracts and took 3. A whole contract over plan is far more than a rounding difference, so it is flagged even though its risk was only €400.

When it shows "—"#

With no flagged trades in the range, there is no Oversized Position card. Each check stays silent until it has its input: no planned size, no risk amount, no limit or too little history each switches one check off. They are skipped, never failed.

How many oversized positions is too many?#

Zero. One oversized loss can outweigh a week of disciplined trades, which is why the Risk Score weights sizing so heavily through Risk Consistency.

How to improve it#

1. Set your max risk per trade. Without it, the risk check can't run. See set your risk limits.
2. Enter a planned size when you log or review the trade, so "bigger than planned" has something to compare with. See edit a trade.
3. Take the drafted rule from MAKE IT A RULE on the Mistakes board: "No position larger than 1.5× my normal clip without writing down why first." See add a rule to a playbook.

Frequently asked questions#

What happened to the Over Leverage mistake?#

It was retired on 12 September 2026. It compared a futures contract's full notional value with your account as if it were a cash position, so it fired on almost every futures trade. Oversized Position now compares what you actually risked with your own limit. Your historical mistake counts dropped when this changed. They are more accurate now.

Does an oversized position lower my Risk Score?#

Not through the flag. The mistake is a label for review and costing. Your Risk Score measures sizing on its own terms: Risk Consistency compares each trade's risk with your typical risk, and Risk Rule Adherence checks your playbook's risk cap. An oversized trade usually hurts both, but the flag itself changes no score.

Is sizing down a mistake in Limbix?#

Not a risk mistake. Winners taken well below your planned size are flagged Under-Conviction Size, which sits in the separate Conviction group: "Backing off your own edge. Not a risk failure." The Risk Score gives full marks for risking less than usual. The two groups never sit side by side on screen for that reason.
