Python MetaTrader5 librairy - copy_tick_from() - flag field value (mt5.TICK_FLAG_...)

[Alex1btz]

Hi,

I use MetaTrader5 python package dl from Pypi. 

I downloaded ticks with copy_ticks_range() and in the result I have a field "flags" uint32. 

On the all the ticks I received I have 3 different values for this field: 4, 130 and 134.

In accordance to https://www.mql5.com/en/docs/integration/python_metatrader5/mt5copyticksfrom_py#tick_flag I have:

print(mt5.TICK_FLAG_BID) #Bid price changed

2

print(mt5.TICK_FLAG_ASK) # Ask price changed

4

print(mt5.TICK_FLAG_LAST) #Last price changed

8

print(mt5.TICK_FLAG_VOLUME) # Volume changed

16

print(mt5.TICK_FLAG_BUY) # last Buy price changed

32

print(mt5.TICK_FLAG_SELL) # last Sell price changed

64

For 4, it seems ok with the few ticks I checked, but I can't find any reason for 130 and 134 (because the sum of all flags is inferior to 130) !

Also 130 + 4 is 134 ! But what could I do with this clue (if it's one)

Any info or idea ? 

Thanks 

Alex 

EDIT: 

Also in the documentation https://www.mql5.com/en/docs/integration/python_metatrader5/mt5copyticksfrom_py

At the end of the page, tick results are showing 134 for the flag value, so I think this is a MetaTrader 5 situation and not related my broker/account

Read the MQL5 reference documentation: CopyTicks .

Especially the comparison part:

//+------------------------------------------------------------------+
//| Returns the string description of a tick                         |
//+------------------------------------------------------------------+
string GetTickDescription(MqlTick &tick)
  {
   string desc=StringFormat("%s.%03d ",
                            TimeToString(tick.time),tick.time_msc%1000);
//--- Checking flags
   bool buy_tick=((tick.flags&TICK_FLAG_BUY)==TICK_FLAG_BUY);
   bool sell_tick=((tick.flags&TICK_FLAG_SELL)==TICK_FLAG_SELL);
   bool ask_tick=((tick.flags&TICK_FLAG_ASK)==TICK_FLAG_ASK);
   bool bid_tick=((tick.flags&TICK_FLAG_BID)==TICK_FLAG_BID);
   bool last_tick=((tick.flags&TICK_FLAG_LAST)==TICK_FLAG_LAST);
   bool volume_tick=((tick.flags&TICK_FLAG_VOLUME)==TICK_FLAG_VOLUME);
//--- Checking trading flags in a tick first
   if(buy_tick || sell_tick)
     {
      //--- Forming an output for the trading tick
      desc=desc+(buy_tick?StringFormat("Buy Tick: Last=%G Volume=%d ",tick.last,tick.volume):"");
      desc=desc+(sell_tick?StringFormat("Sell Tick: Last=%G Volume=%d ",tick.last,tick.volume):"");
      desc=desc+(ask_tick?StringFormat("Ask=%G ",tick.ask):"");
      desc=desc+(bid_tick?StringFormat("Bid=%G ",tick.ask):"");
      desc=desc+"(Trade tick)";
     }
   else
     {
      //--- Form a different output for an info tick
      desc=desc+(ask_tick?StringFormat("Ask=%G ",tick.ask):"");
      desc=desc+(bid_tick?StringFormat("Bid=%G ",tick.ask):"");
      desc=desc+(last_tick?StringFormat("Last=%G ",tick.last):"");
      desc=desc+(volume_tick?StringFormat("Volume=%d ",tick.volume):"");
      desc=desc+"(Info tick)";
     }
//--- Returning tick description
   return desc;
  }
