Lot size
By Aiobot · Oct 6, 2026
Lot size is how large a position is, measured in lots. On many forex names 1.00 lot is 100,000 units of the base currency. The working formula is risk amount ÷ (stop distance × pip or point value). Standard, mini, and micro lots are 1.00, 0.10, and 0.01 on typical FX. Gold and indices use other contracts. Promax can compute the lot; it does not choose the trade.
