Perps and liquidity. Fees in. If liquidation sits before the stop, the page says so in the same view as the size.
Fees, funding per 8h, and the maintenance rate are fractions. 0.0005 is 5 basis points. A positive 8h rate means longs pay shorts. Hold hours spreads that rate over the hold. Targets are 110:50, 120:50 for a price and a close percent. A bare price is a full exit.
The loss fraction is the quote gap per quote deposited, not the classic IL percent. On a 4x move those are 0.5 and 0.2.
20 means 20 percent. This is a flat scenario, not a path of volume.
Short this many base units to flat the delta at this price. It does not cancel the curve.
