Account holders may find themselves holding balances in currencies other than their designated Base Currency as a result of trades in products denominated in a different currency or from profits/losses directly associated with Forex trading. In these cases, IB does not act to automatically convert balances back to the Base Currency as this action would require assumptions as to the account holder's desired currency exposure as well as the trade price at which they would be willing to close the position.¹ IB does, however, provide those account holders who are not active Forex traders an expedited 3 step process for converting such positions at an individual or aggregate currency level.  These steps are outlined below.

Please note the feature below is specific to Trader Workstation. If you are using WebTrader, you must place an order to convert currency. Please see the following link for more information on WebTrader Order Entry: WebTrader Order Entry

Step 1 – View Currency Balances

Select the Account icon from the TWS header.

Step 2 - Select the Position(s) to Close

From the Account window, scroll down to the section titled "Market Value - Real FX Balance", place your cursor on a currency you wish to convert and right-click on the mouse to display the Close Currency menu option. You will be provided with two options, Close Currency Balance which will close the single currency you've selected and Close All Non-base Currency Balances which will close all.

Depending upon the currency quantity you are converting and the market rate, a residual balance may remain as conversions can only be performed in whole currency amounts (e.g. no cents).  The following message will appear advising of this situation and the automated conversion which will take place thereafter.

Step 3 - Review & Transmit Order

Next, an order line for the conversion trade will be populated on the TWS. The order will be set up with default conditions of a market order (“MKT”), good for that day and for the current position quantity². Select "T" to generate the Order Confirmation window using the default conditions or set the price and time conditions as desired.

Note: At times the use of a market order when performing a currency conversion may result in an order rejection due to margin requirements. In order to avoid this, traders may wish to update the order type to a limit order (“LMT”) and set up a limit price. The limit price is the worst price you are willing to trade at; if a better price is available your order will be executed at a better price.

Preview the order from the Order Confirmation window. Note that if your order size is below the IdealPro USD 25,000 equivalent minimum, it will be routed to the odd lot order book. Select the Transmit button when your desired order has been set up.

Once your order has been executed, it may be reviewed through the Trade Log icon from the TWS header.

In the event a residual balance remains, it will be displayed within the Account window (e.g. MXN 7 equals approximately USD 0.56) until the following business day at which point it will be automatically converted to the Base Currency.

¹ IB will act to automatically convert non-Base Currency balances only where the balance is nominal (i.e., below USD 5 equivalent and assuming no subsequent trade activity through settlement) and when the customer requests to close the account (where the balances are below USD 1,000 equivalent)

² Note that the position quantity created by this default will not include balances which are in an accrual state (e.g. interest, dividends).
