Thread: Market Deph in Metatrader 5

I was wondering if any one knows is there any limitation o requisite in acccesing de market deph? does it need to be an active account? or can it be tested in demo? Im onable to access it. I also tried using MarketBookGet() on and EA using the example in the docs

MqlBookInfo priceArray[];
bool getBook=MarketBookGet(NULL,priceArray);
if(getBook)
{
int size=ArraySize(priceArray);
Print("MarketBookInfo about ",Symbol());
}
else
{
Print("Failed to receive DOM for the symbol ",Symbol());
}
having put MarketBookAdd() in the OnInit() function. But it always goes to the part of Failed. Im new to MQL thanks in advance for your help

About DOM, the MQL5 help is referring only to "equity securities".

Trade Orders in Depth Of Market

For equity securities, the Depth of Market window is available, where you can see the current Buy and Sell orders. Desired direction of a trade operation, required amount and requested price are specified for each order.

I suppose DOM will be available also for forex crosses only if your broker is a true ECN broker and only in real account. But it's only my opinion...

Take care
