Hi All,
I am new in MQL5/trading and was learning its coding. One thing which is very strange for me is that when I call MarketBookGet() function on some symbol, it is giving me totally different values than shown in Depth of Market. I might be missing something, due to which I came here to get help.
Below is how I am calling it.
in bookDummy variable I am getting totally different values than what is shown in DOM, like number of records, price levels and volume. Not a single record is matching. I have tried different symbols like AUDNZD, AUDCAD, GBPUSD randomly.
