Lot

In trading, a lot refers to the standardized unit of measurement for the size of a trade.

Since currencies are traded in specific quantities, the concept of a lot helps establish a consistent size for trading. The lot size determines how much of the base currency the trader is buying or selling, and this standardization makes trading more efficient.

There are three main types of lots in trading:

1. Standard lot: represents 100,000 units of the base currency in a currency pair;

2. Mini lot: 1/10th of a standard lot, representing 10,000 units of the base currency;

3. Micro lot: 1/100th of a standard lot, representing 1,000 units of the base currency.

Different lot sizes will require different amounts of margin (the amount you need to open a position). Larger lot sizes will require more margin, while smaller lots require less margin.

In summary, the type of lot affects the risk and capital required for the trade. By understanding lot sizes, traders can better manage their risk, position size, and potential profits or losses.
