Each player starts with 1000 units of each currency of the nations in the Diplomacy game: Crowns, Pounds, Francs, Marks, Lira, Roubles, Piastres. All are equal in value at the start of the game.The deadline for Bourse orders is the same as for the Diplomacy game. The orders are in two parts; SELLING and BUYING. You must always buy as much as you sell every turn. This is most important – see below.

At the start of the Diplomacy game one unit of each currency is worth one US Dollar. However, each time 100 units of a currency are sold its value in relation to the Dollar drops by one Cent. Each time 100 units of a currency are bought its value in relation to the Dollar increases by one Cent. So if in the first season the total of all players’ orders results in 500 more Marks being sold than bought then the Mark would have a value of only 95 Cents the following season. If the total of all players’ orders results in 1000 more Lira being bought than sold then the Lira would be worth $1.10 the following season.If only a net 999 units of a currency are bought or sold then the Dollar value only changes by 9 Cents – all fractions are lost.Each player must buy as much as they sell IN RELATION TO DOLLARS. For example on the second turn, using the values quoted at rule 3 above, a player could sell 100 Lira (worth $110) and then buy 115 Marks (costing $109.25 – again fractions are LOST). If a player makes an error the GM will simply buy as many units of currency as can be afforded.A player may never sell more than 500 units of any one currency in a single turn. You may however buy as much as you can afford.Each season the GM will list all transactions by each player, holdings in each currency and old value and new value of each currency.If a country is eliminated from the Diplomacy game its currency loses all value and any holdings of that currency are worthless. If a country is not eliminated however its currency can never drop below a value of 1 Cent. The value of a currency has no upper limit.Anyone may join the Bourse at any time and will receive 1000 units of each currency still available.At the end of the Diplomacy game each Bourse players ‘credits’ will be calculated by multiplying the number of supply centres held by each country by the number of blocks of 100 units of that country’s currency held (fractions will be carried). The winner of the Bourse is the player with the greatest ‘credits’.Players in the Bourse will usually play under a pseudonym, which allows the players in the Diplomacy game to also take part without giving away any clues as to their future strategy.
