I'm narrowed a logic issue down to return values from the iBarShift function. I'm looking for the offset to other bars (obviously) and it seems that iBarShift will return a positive value even when the bar doesn't exist and the exact param is set to true.
This isn't always happening, I'm getting -1 return values for some bars which don't exist.
I've attached some code which illustrates the problem. The hourly bar for 2007.01.01 06:00 doesn't exist on my hourly chart, yet I'm getting a return offset for bar 2006.12.29 22:00.
Can I get another pair of eyes to check my code to make sure I'm not doing something stupid? If you would be so kind, download the script and run it on an hourly chart, what do you get?
Here's what I get (read output from bottom to top):

PHP Code
int start() { // Test timestamp, this bar should NOT exist in charts datetime dtTimestamp = D'2007.01.01 06:00'; // The shift of the bar on the chart // this SHOULD be -1 since the bar doesn't exist // and the exact param = true int iBarNumber = iBarShift(NULL,PERIOD_H1,dtTimestamp,true); // Let's see what we get Print("Looking for bar with timestamp ", TimeToStr(dtTimestamp)); if (iBarNumber == -1) { Print("Bar not found."); } else { Print("Bar supposedly found at shift ", iBarNumber); Print("Bar at shift ", iBarNumber, " has timestamp of ", TimeToStr(iTime(NULL,PERIOD_H1,iBarNumber))); } return(0); }
