Contract size
The number of units one lot stands for at a broker, such as 5,000 ounces of silver. Two brokers can set different contract sizes for the same instrument, so 1.00 lot is not always the same position.
In Trepeat: when both brokers report a contract size and the two differ, the copy is sized to the same exposure. When either size is unknown, nothing is converted.
