Tick flags codification - how to understand?

[sergey087]

I read about it here https://www.mql5.com/en/docs/integration/python_metatrader5/mt5copyticksfrom_py#tick_flag

But if I do query, server will return flags as 230/100/226 ... etc

How to decode them to really values? Maybe table or formula is allow for decode all possible int values?

Where is it?

Just as the name says — they are "bit flags" or "binary flags". Here are some references for Python ...

Please advise which type of flag corresponds to number 24. Experimentally determined that

• TICK_FLAG_BID = 2
• TICK_FLAG_ASK = 4
• TICK_FLAG_LAST = 8
• TICK_FLAG_VOLUME = 16
• TICK_FLAG_BUY = 32
• TICK_FLAG_SELL = 64

CopyTicks question

Since anding with a bit mask can only result in zero or the bit mask and since non-zero is true	if((tick.flags  &TICK_FLAG_BID)==TICK_FLAG_BID)       s+="BID|"; if((tick.flags  &TICK_FLAG_ASK)==TICK_FLAG_ASK)       s+="ASK|"; if((tick.flags  &TICK_FLAG_LAST)==TICK_FLAG_LAST)     s+="LAST|"; if((tick.flags  &TICK_FLAG_VOLUME)==TICK_FLAG_VOLUME) s+="VOL|"; if((tick.flags  &TICK_FLAG_BUY)==TICK_FLAG_BUY)       s+="BUY|"; if((tick.flags  &TICK_FLAG_SELL)==TICK_FLAG_SELL)     s+="SELL|";
Code can be simplified.	if(tick.flags & TICK_FLAG_BID)    s+="BID|"; if(tick.flags & TICK_FLAG_ASK)    s+="ASK|"; if(tick.flags & TICK_FLAG_LAST)   s+="LAST|"; if(tick.flags & TICK_FLAG_VOLUME) s+="VOL|"; if(tick.flags & TICK_FLAG_BUY)    s+="BUY|"; if(tick.flags & TICK_FLAG_SELL)   s+="SELL|";
