Methods

addDataFieldChangedListener(listener, fieldName, notifyImmediateopt)

Adds a listener that is called when the specified field is updated.

If it's more convenient it's also possible to add leg field listeners directly on the associated module:caplin/trading/trademodel/Trade instance, where the given field names must have the leg prefix prepended, e.g. 'L1_Amount' rather than 'Amount'.

N.b. If the notifyImmediate flag is set to true and there is a possibility that the field in question does not have a value at the point the listener is registered, then the first call to the module:caplin/trading/trademodel/DataFieldChangedListener#dataFieldChanged method may be with an undefined value.

Parameters:
Name Type Attributes Description
listener module:caplin/trading/trademodel/DataFieldChangedListener The listener object to add.
fieldName String The field to listen to.
notifyImmediate boolean <optional>
 if set to true then the listener will be immediately notified of the fields current value, otherwise the listener will first be notified immediately the field changes value. If omitted it defaults to false.

getInstrument() → {String}

Returns the financial instrument that is currently being traded on this leg.

The format of the name is dependent on the asset class. Any processing for specific asset classes should be added to subclasses of TradeLeg. The instrument name is generally not understood by Liberator. Liberator requires a subject name that consists of a concatenation of asset class and instrument name.

Inherited From:

Returns:

Type
String

getMaxTierLimit()

Returns the highest tier limit — this is effectively the highest amount the user can trade.
See:

getNotDealtCurrency() → {String}

getPrice() → {String}

Returns either the bid price or the ask price, dependent on the side previously set with module:caplin/fx/trademodel/FxTradeLeg#setSide.

If the user has clicked the bid button, and hence module:caplin/fx/trademodel/FxTradeLeg#setSide has been called with 'BUY', then the bid price is returned, otherwise the 'SELL' price will be returned.

See:
Returns:
A string formatted decimal.
Type
String

getSettlementDate() → {String}

Returns the date the currencies will be exchanged &mdash also known as the delivery date.

See:

getTermCurrency() → {String}

Returns the term currency from the currency pair — this is the second currency within the instrument name.
Returns:
3-digit ISO currency code.
Type
String

getTierLimit()

Returns the tier limit up to which the currently quoted prices will continue to be valid.

The prices quoted are dependent on the amount traded; generally, the greater the amount, the greater the unit price becomes since it requires the dealer to take a greater exposure to change within the market. The tier limit is the largest amount at which the current price will continue to be valid — if an amount larger than this is set (using module:caplin/fx/trademodel/FxTradeLeg#setAmount), then the quoted prices will update to reflect the new pricing tier.
