[MT4] SymbolInfoTick() does not return Last and Volume

[eabase]

I noticed this before, and thought it was an MT4 issue, but in their docs, it show that this info should be available.
I don't see either Volume or Last coming from the SymbolInfoTick() response.

2020.11.14 00:54:38.034	MtApi_debug EURUSD,M15: OnRequest: Response = {"ErrorCode" : 0,"Tick" : {"Ask" : 1.18335,"MtTime" : 1605311819,"Last" : 0,"Volume" : 0,"Bid" : 1.1832}}

Can you look into this, please?

This works fine for me with this function: Get_instrument_info I used

Hi Shay,

This works fine for me with this ...

Well, are you using this mtapi .NET, or your own TCP/IP connector?
(I'm using Python with the .NET DLL and didn't roll my own.)

For quick reference , the lines mentioned above are shown here .

@eabase This is not might be an issue.
You can check MQL function in MtApi.mq4 and find that function
void ExecuteRequest_SymbolInfoTick(JSONObject *jo, string &response)
fills all the fields of MqlTick (Volume and Last also).

Please check answer #10 to similar question on MQL5 forum:

Indeed seem to be a problem with MT4/5 not populating their returned arguments.

void OnTick()
  {
   long        symbol_volume = SymbolInfoInteger(Symbol(),SYMBOL_VOLUME);
   double symbol_volume_real = SymbolInfoDouble(Symbol(),SYMBOL_VOLUME_REAL);
   long tick_volume_array[],real_volume_array[];

   MqlTick m_tick;
   if(!SymbolInfoTick(Symbol(),m_tick) 
      || CopyTickVolume(Symbol(),Period(),0,1,tick_volume_array)!=1 
      || CopyRealVolume(Symbol(),Period(),0,1,real_volume_array)!=1)
      return;

   Print(TimeToString(m_tick.time,TIME_DATE|TIME_MINUTES),",",
         " m_tick.bid ",DoubleToString(m_tick.bid,Digits()),
         " m_tick.ask ",DoubleToString(m_tick.ask,Digits()),
         " m_tick.volume ",IntegerToString(m_tick.volume),
         " m_tick.volume_real ",DoubleToString(m_tick.volume_real,0),
         " SYMBOL_VOLUME ",IntegerToString(symbol_volume),
         " SYMBOL_VOLUME_REAL ",DoubleToString(symbol_volume_real,0),
         " tick_volume_array[0] ",IntegerToString(tick_volume_array[0]),
         " real_volume_array[0] ",IntegerToString(real_volume_array[0]));
  }

For performance consideration, don't really want to triple my API/EA requests just to get that volume for ticks...
