# How can I calculate the required funds to open an order?

The required funds are determined by the Margin Requirement, which is the amount needed to open a position.

For Forex trading, the calculation is:

Margin Requirement = Number of Lots × Contract Size ÷
 Maximum Leverage ×
 Conversion Rate (if applicable)

For CFDs (Futures, Shares, Indices, Commodities, Treasuries, Currencies, Metals), the calculation is:

Margin Requirement = Number of Lots × Contract Size × Market Price × Margin Percentage × Conversion Rate (if applicable)

Your margin requirement will vary depending on the instrument, leverage, and account base currency.
