“VOLUME” is the financial size of your position in the market, not the funds required to trade. For the purposes of talking “in” the financial markets;

1 lot = 100,000 = @ 200:1 = \$500 risk to client

1 mini lot = 10,000 = @ 200:1 = \$50 risk to client

1 micro lot = 1,000= @ 200:1 = \$5 risk to client

Before you trade with any broker check to see what their definition of a “lot” is, some actually call 1 lot 5,000.

Leverage and Margin requirements

10:1 = 10%

25:1 = 4 %

50:1 = 2 %

100:1 = 1 %

200:1 = 0.5 %

400:1 = 0.25 %

For any other % simply divide, 100/leverage,  to give your margin requirement.

Margin

“MARGIN” is the actual amount of collateral required by the broker to allow the trader to open a position.

Example

1lot = 100,000 units in the market

At 1:200 leverage = 100,000/200 = 500

So to open a \$100,000  position the trader has a financial risk of \$500

Example

1mini lot = 10,000 units in the market

At 1:200 leverage = 10,000/200 = 50

So to open a \$10,000  position the trader has a financial risk of \$50

Example

1micro lot = 1,000 units in the market

At 1:200 leverage = 1,000/200 = 5

So to open a \$1,000  position the trader has a financial risk of \$5

Higher volume trades will require more “margin” by the broker, this will vary from broker to broker. Typical thresholds may be:

Trades up to 1,000,000 Volume = 1:200

Above 1,000,000 to 3,000,000 = 1:100

Above 3,000,000 = 1:50

Example

The margin requirement of 1,400,000 USD/JPY position

1,000,000 has a 0.5% margin requirement (200:1 leverage) which equals: \$5,000

400,000 has a 1% margin requirement (100:1 leverage) which equals: \$4,000

Total (\$5,000+\$4,000) = \$9,000

Some brokers have now changed the way they calculate the “Margin” requirements to open a position.

Example

Buy 1.0 Lot EURUSD at 1.3000

Margin Requirement for EURUSD: 0.5% (200:1)

Margin Usage would be = 100,000 x 1.3000 x 0.5% = \$650

Under current settings, when a Hedged Sell 1.0 Lot EURUSD was entered, the Used Margin would drop to \$0.

In the new setting, the Used Margin will remain at \$650.

Example

Buy 5000 EURUSD at 1.3000

Currently, this position requires a minimum \$25 Margin Requirement (regardless of the price of the EURUSD).

Under some systems, Margin will be calculated based on current dollar value of the position.

5000 X 1.3000/200 = \$32.5

It is very important to check the “MARGIN” requirements required to open a position with your Broker/Market Maker before you begin to trade. If you do not, you may find that your positions have been closed by your Broker because insufficient funds are in your account to support your open positions.
