Hi jcl,

I've found another bug (version 2.50.2), I guess it is somehow related the previous issue.

Zorro executes ticks twice:
- once for data from t6 historical file
- once more for data downloaded from broker (my guess)

It happens under certain circumstances, as an example:
- BarPeriod = 60
- TICKS and PRELOAD are set (doesn't happen if PRELOAD is not set)
- Data source is t6 file with 1 min resolution (doesn't happen with t1 file in my experiments)
- Last data point in t6 file is at 17:56 UTC
- Script starts at 18:47 UTC

Script executes tick() for historical data up to 17:56 UTC, then tick() time goes back to 17:01 UTC instead of continuing 17:57 UTC.

Code:
Code
void recentDataPrint(int type, int duration)
{
	int timestampNow = utm(wdate(NOW));
	
	var dateData = wdate(0);
	int timestampData = utm(dateData);
	
	if ((timestampNow - timestampData) < (duration * 60 * 60)) { // show up to x hour to prevent spamming message window
		printf("%s timestamp: %s \n", ifelse(type, "Bar", "Tick"), strdate("%d %b %y %H:%M:%S", dateData));
	}
}

void tick()
{
	recentDataPrint(0, 2);
}

void main()
{
	History = "History\\Dukascopy\\*.t6";
	// History = "History\\DukascopyT1\\*.t1";
	
	BarPeriod = 60;
	
	set(LOGFILE, TICKS, PRELOAD);
	Verbose = 3;
	
	LookBack = 20;
}

void run()
{
	recentDataPrint(1, 3);
}
