BarsArray

[mballagan]

The following code causes an exception when trying to access the first bar on the chart:

Print("Number of bars is : " + BarsArray[0].Count.ToString());
Print("Number of time elements is : " + Times[0].Count.ToString());

try{

Print("The first bar on the chart is: " + Times[0][Times[0].Count-1].ToString());

}
catch(Exception ex)
{
Print("Error: " + ex.Message);
}

Sample output is:

Number of bars is : 14479
Number of time elements is : 14479
Error: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

If you want the first bar of the chart just do Times[0][CurrentBar].

loop

I would actually also like to loop through all the bars as in the following example where I want to do a calculation based on bars in a certain date range:

//calculate highest high in period Start Time to End Time
for(int i = 0;i<Times[0].Count;i++)
{
if(Time[i] >= dtStart && Time[i] <= dtEnd)
{
Print("The current bar time is : " + Time[i].ToString());
}

}

But this causes an exception as before:

Error: Index was out of range. Must be non-negative and less than the size of the collection.

Don't loop with .Count. Loop with CurrentBar.

DateTime

Thanks CurrentBar has worked.

In the for loop below we are comparing each bar to see if it falls within a certain time range but it doesnt seem to be working properly as
bstart is always true and bend is always false even though this is clearly not the case from looking at each bar time.

for(int i = 0;i<CurrentBar;i++)
{
Print("The current bar time is : " + Times[0][i].ToString());
DateTime dtCurrent = DateTime.Parse(Times[0][i].ToString());
bool bstart = dtCurrent >= dtStart;
Print("The current bar time > dtStart : " + bstart.ToString());
bool bend = dtCurrent <= dtEnd;
Print("The current bar time < dtEnd : " + bend.ToString());

// if(Times[0][i] >= dtStart && Times[0][i] <= dtEnd)
// {
// Print("The current bar time is : " + Times[0][i].ToString());
// }
}

You'll need to debug your variables. Print out what everything is at every step of the way.

type conversion

Is there some type conversion that has to be done if comparing
Times[0][i] to a DateTime variable?

[NinjaTrader_JoshP]

Shouldn't be needed. They should be DateTimes.
