What is the minimum amount required to trade?

How is the minimum margin required calculated?

The minimum margin required to trade will depend on the market and instrument you are trading.

You can find the minimum margin required by applying the minimum lot size to the normal margin requirement formula, which is the following: 

Margin Required = (Contract Size x Lot Size x Open Price) / Leverage. For example, the minimum margin required to trade US30 with an open price of 37330 is the following:

Minimum Margin Required = (10 x 0.01 x 37337) / 200 = 18.67 USD
