Title: Number of networks

Message:
 On your About.html page, you state the following:
 
 "The number of neural networks currently in our library varies from day to day, but normally contains more than 400."
 
 Is this correct?

Response:
There are about 200 networks right now in our forecast library. We haven’t added or removed networks for several months.

The forecast is computed by averaging the predictions of all of the networks in the library. The networks differ in size and structure and in the values of their internal weights. The differences are the result of the randomness of the solution procedure and variations in the collections of market data used in learning. You can think of the networks as a group of experts analyzing the current market data and then making a prediction of where the market is headed.
