The OANDA FXTrade Platform allows currency trading on a margin basis. There
is an upside and a downside to margin-based trading. The upside is that the
trader can strongly leverage the funds in the account and generate a large profit
relative to the amount invested. The downside is that the losses can be just
as great, and the trader can easily risk all of the funds in the account. Hence
it is important that traders fully understand OANDA's margin rules as described
below before they start trading.
What is margin trading
When a trader buys (goes long) or sells (goes short) a currency pair, then the value of the currency pair, as an instrument, is initially close to zero. This is because (in the case of a buy) the quote currency is sold to buy an equivalent amount of the base currency. As the market rates fluctuate, however, the value of the currency pair position held will also fluctuate. Thus, if the rate for the currency pair goes down, the trader's long position will lose value and become negative. To ensure that the trader can carry the risk in the case a position results in a loss, banks typically require sufficient collateral to cover those losses. This collateral is typically referred to as margin.
Margin-based trading refers to trading in transaction sizes larger than the
funds in the account. By leveraging the funds in the account, traders can take
better advantage of small movements in the market to build up profits quickly.
Conversely, leveraging one's account to trade in larger transaction sizes can
just as easily work against a trader and magnify losses, essentially putting
most of the funds in the account at risk.
OANDA's margin rules
There is no minimum margin deposit required to open a trading account with
OANDA. However, OANDA's FXTrade Platform enforces two rules or requirements:
5% margin requirement for new trades
The OANDA FXTrade Platform requires that trading customers have at least 5% collateral on all positions when a new trade is made. Thus, in order to buy or sell 1,000,000 EUR/USD, a trader must have the equivalent of 50,000 Euros in value in his/her account. The margin can be comprised of cash holdings in the trader's home currency, or of unrealized profit in the open positions he/she might have.
Fully understanding this in detail, unfortunately, involves some math. Consider the following definitions:
With these definitions, then the 5% margin requirement for new trades states
that if a new trade were to be executed then 5% of the Total Position Amount
must be less than the Account Equity immediately after execution of the trade
should the trade go through. For example, if a trader has Account Equity of
$2,000, two open positions consisting of
- long 10,000 units USD/CHF and
- short 20,000 units EUR/JPY,
the current EUR/USD exchange rate is 0.9134/06, and the trader would like to
buy an additional 5,000 units of USD/CHF, then the Total Position Amount should
the trade be executed would be:
10,000 + (20,000 * 0.9134) + 5,000 = 10,000 + 18,268 + 5000
or $33,268. The 5% margin requirement for new trades states that 5% of $33,268
(which is equal to $1,663.4) must be less than the Account Equity. In this example,
Account Equity is $2,000, $1,663.4 is less than $2,000, so the new trade will
be executed successfully.
Another way to look at it is if the new trade does not offset an existing open position, then the Margin Available must be greater than 5% of the number of units to be traded when converted to USD using the ask rate. Hence, if the Margin Available is $6,000, the current EUR/USD rate is 0.9134/36, the trader has no open EUR/USD position at the time, and the trader submits a sell trade for 100,000 EUR/JPY, then the margin requirement is met and the trade can be executed, because $6,000 is greater than 0.05 * (100,000 * 0.9136) = 0.05 * 91,360 = $4,568. On the other hand, if the Margin Available is $4,500 and the trader submits a sell trade for 100,000 EUR/JPY, then the trade will be rejected by the system "due to insufficient funds", because $4,500 is less than the $4,568 margin requirement.
The buy/sell window of the user interface displays the maximum trade size for
the trade being considered, given the margin available for the trader.
2.5% margin requirement for open positions
The margin requirement for open positions states that the Account Equity must, at all times, be larger than 2.5% of the Total Position Amount. If this requirement is not met, then the OANDA FXTrade Servers will automatically liquidate all open positions in the account using the prevalent market exchange rates at the time of liquidation. The OANDA FXTrade Servers continuously monitor the value of all positions in all accounts to determine whether the 2.5% margin requirement is met and when open positions need to be liquidated. The trader must assume that such a liquidation will happen without warning, and it is the responsibility of the trader to monitor his or her account to see if this might happen. We strongly recommend that traders make use of Stop/Loss limits to limit their risks. There are two ways a trader can prevent total liquidation of his or her open positions: (i) close a portion of the existing open trades so as to increase the available margin, or (ii) transfer additional funds into the account so as to increase the Account Balance.
If a trader is logged in, then the system will make an attempt at warning the
trader when the Account Equity drops below 4% of the Total Position Amount,
and again when the Account Equity drops below 3% of the Total Position Amount.
The warning takes place through a window that pops up automatically.
Limiting risks
Trading on a margin basis means that any market movement will have a proportionate
effect on a trader's Account Equity. This can work for a trader as well as against
a trader. The possibility exists that a trader could sustain a total loss of
funds. We strongly encourage traders to continuously monitor that status of
their account and to specify a stop-loss order for each open trade in order
to limit downside risk. A stop-loss order specifies that a trade should be closed
automatically when the exchange rate for the currency pair in question reaches
the specified threshold. For long positions, the stop-loss rate is always lower
than the current exchange rate; for short positions, it is always higher. The
stop-loss rate can be specified at the time the trade is issued, or a stop-loss
order can be added at any time for any open trade. Moreover, the OANDA FXTrade
Platform allows traders to change their stop-loss orders at any time to take
current market prices into account. This can be achieved by clicking on an open
trade in the "Open Trades" table and then suitably "modifying"
the trade in the resulting pop-up window.
