(This post is for the MatLab experts only)
Can anybody help me with connecting MetaTrader3 API to MatLab? Some basic steps I can solve:
loadlibrary('mtapi.dll','mtapi.h');
Now I can call some library functions:
example:
verzeion=calllib('mtapi', 'MtGetVersion');%
socket1=calllib('mtapi', 'MtCreate');
return_code=calllib('mtapi', 'MtConnect',socket1,'217.74.44.14',1950); %alpari demo
Now I can login in proviously (in metatrader) created account:
return_code=calllib('mtapi', 'MtLogin',socket1,656816,'my_password')
I can also make pounters to receive actual prices:
bid_ptr=libpointer('doublePtr',0);
ask_ptr=libpointer('doublePtr',0);
and then:
return_code=calllib('mtapi','MtGetPrices',socket1,symbol_ptr,100,bid_ptr,ask_ptr)

However, I do not know how to deal with remaining functions returning pointers to structures: For example, the functions:MtGetRates, MtGetTradeHistory,MtDeleteOrder, MtSetPumpingMode, MtGetUpdatedTickInfo , etc I don't know how to deal with.
Could anybody help me with this functions?
Regards
F.

Thank you. I have read this help carefully but still I can't solve it. My functions don't work.
