A lot is the standard unit size of a transaction.
Depending on the financial instrument traded, the lot size is determined; i.e. a standard lot traded at Windsor, for Forex trading, usually consists of a contract size of 100,000 (units of the base currency).
The contract size is then proportionate as per the lot indication – standard, a mini or micro lot.
As a result, a standard contract size of the GBPUSD is 100,000 GBP then the mini lot consists of a contract size of 10,000 GBP and the micro lot consists of 1,000 GBP accordingly.
For details on all instruments traded at Windsor, please refer to the Contract Specifications document of each account type.
