I do this for timed based bar
PrevTN = StaticVarGet("TimeNumber");
TN = LastValue(TimeNum());
NewBar = TN != PrevTN;
StaticVarSet("TimeNumber",TN);
This should work for any bar type
newday=day()!=ref(day(),-1);
PrevBN=StaticVarGet("BarofDay");
BN=lastvalue(barssince(newday,1));
newbar=BN!=PrevBN;
StaticVarSet("BarofDay",BN);
if (newbar)
{..... do trading code
}

Subject: [amibroker] Re: Question regarding real-time trading
I might be missing something in your question but if you want to know if a new
bar has arrived, you could just check the value of barindex?
LastBar = LastValue(BarIndex());
prevLastBar = StaticVarGet("prevlastbar");
// Initialise
if (IsNull(prevLastBar)){
prevLastBar = LastBar;
StaticVarSet("prevlastbar", prevLastBar);
}
if (LastBar > prevLastBar){
_TRACE("New Bar");
StaticVarSet("prevlastbar", LastBar);
}
Regards,
Jules.
