How to calculate margin requirements

In its simplest terms, a margin is the amount of money which is required for having an open forex or CFD trading position.

Free margin refers to the free amount of money which can be used for opening additional positions.

Margin requirements may vary dependent on various reasons, including what asset you are trading, the amount of leverage you have, your trading volume and positions, and other market situations.

BlackBull Markets provides our traders with the MT4/MT5 trading platform which provides a continuously updated feed regarding your margin. But if you want to calculate margin on your trade, follow the formula and example below.

Margin Formula:

Margin = (Notational volume * Current Trading Value of currency) / Leverage.

Where, Notational volume is the amount of lots multiplied by 100,000 units.

Example:

  • BlackBull Markets offers leverage of 1:500
  • Assume a balance of $1000
  • And you were trading the EURUSD, which is currently trading at 1.11890 mark.
  • And you were trading 3 lots.

If we were to enter these quantities into our Margin Formula:

= ((3*100,000) *1.11890) / 500

= (300,000 * 1.11890) / 500

= 335679 / 500 = 713.40 = Margin

This formula indicated that the higher your leverage, the smaller your margin required will be.

Free Margin Formula: Equity – Margin = Free Margin

Example: 400 - 713.40 = 313.40

Margin Percentage Formula:  Equity / Margin= Margin %

Example: 400 / 713.40 = 56.07%

Once you account reaches a Margin percentage below 75%, you will receive a margin call.

Below 50% you will be stopped out / liquidated. Meaning all your open positions will automatically be closed.

To prevent a stop out more funds will be required, or open positions must be closed.

With our example we can see that a margin call would have been received by this point and out account is nearing a stop out.

All these calculations are provided on the MT4 platform. However, it is important for a successful trader to understand how these figures are derived and what they represent.
