Short answer
ORIN divides your dollar risk (account × risk %) by the per-unit risk (distance from entry to stop, times the contract size). Size is the output of that division — it is never an input.
Steps
- 1Set your account sizeSettings → Risk defaults. This drives every position size and budget bar on the desk.
- 2Set risk per tradeTypically 0.5–2%. Under 1% is conservative; above 2% makes a five-loss streak cost more than 10% of the account.
- 3Let the stop decide the sizeA wider invalidation produces a smaller position at identical dollar risk. That is the formula working, not a problem to fix.
Worth knowing
- Forex uses 100,000 units per standard lot. Futures use the contract multiplier — NQ is $20 per point, MNQ is $2, and mixing them is a 10× sizing error.
- The figure assumes your stop fills where you placed it. Gaps and thin books do not honour that.

Settings → Risk defaults → Max daily loss (%). The Risk view then shows a budget bar tracking realised losses against that cap, with the remaining headroom expressed in losses rather than percentages.
How to apply a rule pack
Open Library → Guru Packs and choose a pack, or use the lens switcher on the Analyze screen. Applying a pack replaces your grading lens: hard rules cap the grade when broken, and confluences reweight it.
