Order could be executed below a variable price, expressed as a percentage of spot price in each moment. The maximum price will increase or decrease together with spot price, but will be limited by selected price. Limit price represents a fixed price, under no circumstances will order be executed for a price that is higher than limit price. Additionally, order won't be executed when the spot price is below the stop price. In this case the order will be temporarily deactivated and will be re-activated once the spot price rises above the stop price. Stop price is a fixed price, expressed as a percentage of spot price in the moment when order is activated.
