How to identify tick flags?

New comment
 

I tried to export ticks data using Python and I got the data, but I don't identify what does 2, 4, 6, 312, 344, 376 flag codes means?

Hi William, I have a question: How could 2, 4, 8, 16, 32, 64 sum up to 312 or even 1026 in my case for the uint flags? Also by doing

if ((bool)(tck1.flags & TICK_FLAG_LAST) || (bool)(tck1.flags & TICK_FLAG_VOLUME)
    || (bool)(tck1.flags & TICK_FLAG_BUY) || (bool)(tck1.flags & TICK_FLAG_SELL)
  )

one cannot capture all the trades as shown in the "Draw Time and Sales" dots of Depth of Market window. Sorry I failed to find the correct way from MQL5 document and forum to extract all the trades performed from MqlTick[], but what is the correct way that "Draw Time and Sales" in MT5 performed?


Thanks.

There are some internal (undocumented) flags, just ignore them.

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

From your screenshot :

312 => 312-256 = 56   -> flags 32+16+8
344 => 344-256 = 88   -> flags 64+16+8
376 => 376-256 = 120 -> flags 64+32+16+8

I don't see 1026 in your screenshot ? But I suppose the same logic can be applied (1026 => 1026-1024 = 2 ?).
