4.4.2OnPriceChange handler

Instead of using the main OnMessage handler, you may find it easier to watch price changes using an OnPriceChange handler. If defined, this is called by the framework with each individual price (not an array/list) which is changing:

Framework.OnPriceChange = function(quote) {

// The quote object contains the same time, bid, ask etc properties listed above.

// Instrument which is changing is in quote.instrumentId.

// Prices are in quote.ask and quote.bid etc.

};

The quote object which is passed to OnPriceChange() has the following properties:

Property	Description
instrumentId	ID of the instrument, such as EUR/USD
time	Time of the most recent quote
bid	Latest bid price
ask	Latest ask price
high	High of the current period. Availability depends on account features.
low	Low of the current period. Availability depends on account features.
change	Change amount during the current period. Availability depends on account features.
changePc	Change amount as a percentage. Availability depends on account features.
