My position size looks wrong
When a fill is bigger or smaller than you expected, a quantity setting is usually the cause. This guide walks each one.
Your fill came in bigger or smaller than you expected. A quantity setting almost always explains it. Work through the checks below to find the one that changed your size.
Lune sizes each order from your quantity mode, any per-account multiplier, and your caps. One of these usually explains a surprise size.
Open the automation or copy setting and check how quantity is set. A fixed quantity places the same size each time. A mode that scales by account size gives a different size per account. Confirm the mode matches what you want.
Each account can carry a multiplier that scales the base quantity up or down. A multiplier of 2 doubles the size on that account. Open the account settings and confirm the multiplier is what you expect.
Micro and mini contracts are different sizes of the same market. If a size looks off by a large factor, confirm you are trading the contract you meant. A mini is much larger than its matching micro.
A max position cap limits how large a position can grow on an account. If your size is smaller than expected, the cap may have trimmed it. Open Risk Management and review the cap.
Start from the base quantity, apply the multiplier, then apply any cap. Compare that result to your fill. This shows which step changed the number.
