We are a new Forex brokerage firm. We buy and sell currencies & commodities for our clients. What we require is an Accounting software to record transactions of our clients. The Software should have the following abilities :- 1) We should be able to input transactions of our clients individually. 2) Each client will be assigned an account number.

This transaction will earn him a profit of 25000. And commission earned by the firm on each lot is 500 either in profit or loss. If a client sells one (1) Lot of Gold at $1075 and market prices increase to $1100 than he will incur a loss of 25000. And commission earned by the firm on each lot is 500 either in profit or loss. The market value will be entered manually by the operator the system should be able to generate the above accounting A statement should contain settled and unsettled positions. Where the above transactions in example are all settled. If the client buys gold then he has to sell it to make it a settled positions otherwise it will be unsettled and trade is still open.
