Hello,

Does anyone know if TICK_FLAG can have a larger value of 252?

Using CopyTicksRange I get TICKS_FLAGS which has 256 more than the flag.

Example: TICK_FLAG 312 instead of 56.

Is that correct?

6    = 0110                      // all digit "1" is a flag position

252 = 1111 1100            // all digit "1" is a flag position

312 = 0001 0011 1000    // all digit "1" is a flag position

string GetTickFlag( uint tickflag )
{
  string flag = " " + (string)tickflag;

#define TICKFLAG_MACRO(A) flag += ((bool)(tickflag & TICK_FLAG_##A)) ? " TICK_FLAG_" + #A : ""; \
                          tickflag -= tickflag & TICK_FLAG_##A;
  TICKFLAG_MACRO(BID)
  TICKFLAG_MACRO(ASK)
  TICKFLAG_MACRO(LAST)
  TICKFLAG_MACRO(VOLUME)
  TICKFLAG_MACRO(BUY)
  TICKFLAG_MACRO(SELL)
#undef TICKFLAG_MACRO

  if (tickflag)
    flag += " FLAG_UNKNOWN (" + (string)tickflag + ")";

  return(flag);
}

void OnStart()
{
  Print(GetTickFlag(312));
  Print(GetTickFlag(344));
  Print(GetTickFlag(376));
}

Result

312 TICK_FLAG_LAST TICK_FLAG_VOLUME TICK_FLAG_BUY FLAG_UNKNOWN (256)
344 TICK_FLAG_LAST TICK_FLAG_VOLUME TICK_FLAG_SELL FLAG_UNKNOWN (256)
376 TICK_FLAG_LAST TICK_FLAG_VOLUME TICK_FLAG_BUY TICK_FLAG_SELL FLAG_UNKNOWN (256)

Yes it's correct. The additional bit used for internal management by MT5.

...and TICK_FLAG is of type uint, so the value may be 4 294 967 295

Yeah and will be the semantic of higher bits ? This bit-8 is already undocumented. However with Metaquotes all is possible I guess.

Please don't double post. Doing that you are wasting people time.

Thanks for wasting mine and others' time by selfishly posting the same question twice. (sarcasm)
