class IO2GMarketDataSnapshotResponseReader

Brief

The class reads a stream of historical prices.

Details

If you need historical prices information, you must request it. The process of requesting historical prices consists of several steps that are described in the How to get historical prices section.

As an answer to the historical prices request, the trading server sends a response object of the MarketDataSnapshot type. This object is the response parameter in your implementation of the IO2GResponseListener.onRequestCompleted method. To process the response contents, you must use an instance of the IO2GMarketDataSnapshotResponseReader class.

To create an instance of the IO2GMarketDataSnapshotResponseReader class, pass the response object as an argument to the IO2GResponseReaderFactory.createMarketDataSnapshotReader method. For example,

O2GMarketDataSnapshotResponseReader marketDataReader = factory.createMarketDataSnapshotReader(response);

Example

 void ResponseListener::onRequestCompleted(const char *requestId, IO2GResponse  *response)
 {
     //...
     if (response->getType() == MarketDataSnapshot)
     {
         O2G2Ptr<IO2GResponseReaderFactory> factory = mSession->getResponseReaderFactory();
         if (factory)
         {
             O2G2Ptr<IO2GMarketDataSnapshotResponseReader> reader = factory->createMarketDataSnapshotReader(response);
             //...
         }
     }
 }
