Standardized trade size. 1 standard lot = 100,000 units of base currency.
Forex lot sizes are: standard (1.0 = 100,000), mini (0.1 = 10,000), micro (0.01 = 1,000). Smaller lots let new traders practice with controlled risk.
On MetaTrader 5 with Coral Markets, lot size is set on the order ticket and directly drives pip value and required margin.
Coral Markets publishes a full trading glossary so working traders can quickly check definitions in plain English. Every term ties back to how the concept actually shows up on MetaTrader 5 and on real charts.
