Required Margin for FX Pairs Formula:
Required Margin = Lots × Contract Size × Market Price × Margin Rate
・Lots: Trading volume (e.g., 1 lot = 100,000 units)
・Contract Size: Can be checked in MT4/MT5 by right clicking the symbol in the Market Watch window and selecting “Specification”
・Market Price: Current price of the instrument
・Margin Rate: Depends on leverage (e.g., 1%)
Required Margin for Indices, Precious Metals, and Oil Formula:
Required Margin = Lots × Contract Size × Market Price × Margin Rate
Note: Although the formula is the same as for FX pairs, contract sizes and pricing units vary by product. Always confirm specifications in the platform.
If the margin needs to be converted into the base currency of your trading account, apply the relevant exchange rate separately.
Lot Size Reference
1 lot = 100,000 units
0.1 lot = 10,000 units
0.01 lot = 1,000 units
