Limited bullets. Make them count.
Rule-aware grades, drawdown-safe sizing, and a hard stop on the C-setup that ends evaluations.
Every tool sold to funded traders works on the last line. The account is lost on the first three.
Drag the budget and watch the desk change its mind
Grades are capped by the firm's rules, not annotated with them. Spend the day's budget and nothing clears — which is the correct answer, not a broken one.
Sweep and reclaim into the London window, structure agreeing on the 1H.
Momentum continuation, but the invalidation sits far enough away to cost multiple bullets.
Sample Two worked examples, not live candidates. The budget maths above responds to the firm and the slider you picked; the setups it is judging were written by hand.
Presets approximate each firm's published evaluation rules; the per-trade figure is a conservative fraction of the daily limit, not a firm rule. Check your own account terms — firms change them.
Grade against your rulesPresets approximate published evaluation rules; the per-trade figure is a conservative fraction of the daily limit, not a firm rule. Confirm your own account terms.
A day inside an evaluation
Told in bullets rather than hours, because that is the unit a funded trader actually counts in.
- Bullet 1
The good one, taken at the right size
A-grade in the London window, stop where the structure breaks, size derived from that stop. It loses anyway — most good trades do, some of the time. Budget consumed: 10%.How size comes from the stop - Bullet 2
The second one, same size
Also a valid setup, also stopped. Two losses in and 20% of the budget is gone. Nothing has gone wrong yet — this is what a normal bad morning looks like. - Bullet 3
The one where you want to size up
Here is where evaluations die. The instinct after two losses is to make it back on the next one, and doubling size turns a 20% day into a 60% day on a single trade. The desk sizes it identically and shows the budget it would consume. - No bullet
The C-setup at 15:40, capped to F
It looks tradeable. It sits inside a news window and needs 2.7× your per-trade budget for its stop. The grade goes to F with both reasons named, and you go home with an account.How plans get capped by rules
Nothing in that day required a better entry. It required the same size four times and one refusal — which is exactly the part no indicator has ever helped with.
The breach maths, stated plainly
Filtered to this context: not accuracy, but how much room your rules actually give you.
The first two numbers are arithmetic, not claims — you can check them on the desk above. The fourth is the one a competitor would invent, and it stays a dash until enough funded traders have run evaluations for it to mean something.
How the calibration worksWhat you'll use during an evaluation
Three surfaces, in the order they matter when your constraint is drawdown.
Position Sizing
Prop-firm presets fill balance and a conservative risk-per-trade, so size is right before the chart is even open.

Apply a rule pack and the plan is sized against the daily limit, with headroom stated in losses rather than percentages.

Chart, grade and rule state on one screen — so the constraint is visible at the moment of the decision.
Live AI StudioWhat this cannot do for a funded account
The honest list, because your account terms are stricter than most software's promises.
It cannot block an order
No broker connection, no automation. The desk can cap a grade to F and explain why; clicking buy anyway takes one second and ORIN will not know you did. The discipline stays yours.
Presets approximate, they do not guarantee
Firms revise their rules, vary limits by account type, and measure drawdown differently — some from the day's open, some from peak equity. Treat a preset as a starting point and read your own terms.
Trailing thresholds move under you
An Apex-style trailing drawdown rises with your equity high-water mark, so yesterday's headroom is not today's. The desk models the static case; the trailing case needs your live balance, which lives with your firm.
No pass-rate claims
Every competitor in this space quotes a pass rate. We do not have a sample large enough to publish one honestly, so there is not one on this page — including in the proof strip above, where the dash is deliberate.
The instruments where this matters most are gold and the indices — that page covers the news-window behaviour that ends more evaluations than bad entries do.
Questions traders actually ask
Almost nobody fails an evaluation on entry quality — they fail on a breach. The maths that matters is how many losses your daily limit can absorb at your chosen size, and whether you stop when it is spent. ORIN caps grades against those limits so the constraint is visible before you click, not after.
The most an account may lose in a trading day before the firm closes it. Most firms measure it from the day's starting balance, some from peak equity, and the difference matters. Set the preset to your firm and check your own terms — firms revise these.
At 0.5% risk against a 5% daily limit, ten. That is the number worth internalising, because it converts an abstract percentage into a countable thing you can feel spending. Below about five bullets, one bad sequence ends the day and often the account.
It caps the grade to F and says why. It cannot place or block orders — there is no broker connection anywhere in ORIN — so the last step is still yours. What it removes is the excuse that you did not know.
FTMO, Topstep and Apex presets ship today, covering the common evaluation shapes: percentage daily limits, fixed dollar limits and trailing thresholds. Any other firm can be entered manually with its balance and limits.
The journal records every decision with the rule state at the time, so you can see which rules you actually followed rather than which you intended to. Pass-rate statistics are not published yet — that needs a sample we do not have.
