Hello there!
1) Could somebody tell me what exactly triggers BookEvent? Does it use volumes of buy vs sell orders and if yes how to obtain those programatically in real time? Is it fair to say that this event only relevant to current tick(time)? How often on average does this event occur?
2) Also, I was wondering if neural network is used in tester's genetic algorithm, if it is, could somebody describe it here, layer-count, type, some logic etc. Maybe even a drawing! If there is no ANN then never mind.
Thank you
Burton

1. Please refer to documentation:
BookEvent
The BookEvent event is generated by the client terminal after the Depth Of Market is changed; it is processed by the OnBookEvent function. To start generation of BookEvent for the specified symbol, it is necessary to subscribe the symbol to this event by using the MarketBookAdd function.
To unsubscribe from BookEvent for a specified symbol, it is necessary to call the MarketBookRelease function. The BookEvent event is a broadcasting-type event - it means that it is sufficient to subscribe just one Expert Advisor for this event, and all other Expert Advisors that have the OnBookEvent event, will receive it. That's why it is necessary to analyze the symbol name, which is passed to a handler as a parameter.
This event is connected with changes in the depth of market. Nobody can tell how often it occurs, it behaves just like the price flow.
2. No neural networks, for more details refer to the client terminal documentation
Thank you, Alexx! The links are spot on! Couldn't find them on my own, silly me. Thanks again!
