Position size calculator
Risk-based sizing, checked against the price at which the position is actually closed. At 10× the liquidation sits 5.26% from the entry and the stop 5.00% away, so the stop executes first.Your stop is the entry price, so there is no distance to size a position from. Entry defaults to ARB’s mark price, $0.20435.
Not investment advice — modelled figures from stated assumptions. Terms and disclaimer
Liquidation sits between the entry and the stop, so the stop never executes. The position is closed by the venue first, and the loss is the whole margin, taken at a smaller move than the stop was sized for.Liquidation and the stop are too close to call, so which of them triggers first is not something this model can say.The stop is reached first, so the loss is bounded by what you budgeted. Liquidation lies further from the entry than the stop does, which is the whole test.The stop is not on the losing side of the entry, so nothing modelled here can reach it.With the stop at the entry there is no distance to size from, so no position is drawn, and no liquidation. Distances are to scale; the liquidation price is the venue’s tier-correct one.
Why sizing alone is not enough
The standard formula — risk budget ÷ distance to stop — sizes the position so that
if the stop fills, you lose exactly what you budgeted. It says nothing about whether
the stop is reachable. Leverage sets the liquidation price independently, and when liquidation
falls between entry and stop the exchange closes the position first. The stop is then decoration.
The check has to use the tier-correct liquidation price.

notional this contract sits in tier 1, where maintenance margin is
5.000% — so at 10× liquidation sits 5.26% from entry, where the common
entry × (1 ∓ 1/leverage) formula reports 10.00%:
$0.00968 of room that is not there. Both are measured from entry, so the two percentages compare directly.Which tier applies depends on the position’s notional, and with the stop at the entry there is no position to place in one. ARB’s tier-correct liquidation against the formula, on its contract page →
Fees, slippage and funding are not deducted here, and a gap through the stop can exceed the budgeted loss regardless of sizing. Maintenance margin is read at the tier your notional falls in; a size large enough to cross a boundary moves it further.
