i've seen positionLeverageUpdated sometimes be a weird value. on android i'm just checking input.amount == nil

if input.amount is "0" though or "000" etc, i wanted to avoid that


if hasNoInput {
// no input, no change, update accordingly
viewModel?.liquidationPrice?.direction = .none
if currentLeverage <= 1 {
if currentLeverage <= 1 && side == Abacus.PositionSide.long_ {

up to you on whether you want to simplify this if else - on Android i didn't end up doing any complex checks on leverage or side. i just used hasNoInput and liquidation price directly. if it is nil, it's because there is no liquidation price (leverage <= 1 and long).

How did u decide to display "None" or not then?
