-Formally, the capacity is a list of terms, all but the first preceded -by one of -, minus, +, -plus. Each term may specify a mass and/or a volume -(separated by a space), as a number followed (without an intervening -space) by a unit (t, kg, kl or -l). Alternatively each term except the first may specify a -percentage, which is applied as a percentage change to the answer from -all the preceding terms. The first term may be a ship name or -abbrevation instead. If the first term specifies only one of mass or -volume, all the subsequent terms may only adjust that same value. +More formally: +

--Trades whose margin is less than the expected loss are never selected. -For example, if you select 1% loss per league, and plan a voyage of 5 -leagues, then any trade with a margin of less than 5.15% would be -completely excluded (5.15% not 5% because the loss works like compound -interest). Theoretically very profitable trades which are close to -the expected break-even point because of the distance can also be -rejected by the optimiser in favour of shorter distance trades with -theoretically smaller margins. +Trades whose margin is less than the expected loss are never included +in the suggested plan.
