Frequently Asked Questions
How is the required margin calculated?
It is trade size divided by leverage. Trade size is lot size x contract size (normally 100,000 units, or 100 ounces for gold) x rate. For example, trading one lot of USD/JPY at a rate of 150 with 1:25 leverage gives a trade size of 100,000 units x 150 = 15,000,000 JPY, not 1,000,000 units, so the required margin is 600,000 JPY.
What margin level should I keep?
Margin level is account balance divided by required margin x 100. Many Japanese brokers close positions once it falls below 100%. To absorb open losses and sudden moves, many traders keep 300-500% or more in practice, and the more headroom you keep, the further price can travel before a stop-out.
Does higher leverage make losses bigger?
Leverage itself only lowers the margin required; what decides the size of your profit or loss is the lot size. That said, needing less margin makes it easier to open a large lot, which is how losses end up growing. It is safer to decide the loss amount first with the lot calculator.
