Issue with my if statement

[daaim0]

Hello

I'm trying to do a few calculations based on the condition that there has been a change in price. I did it doing the following way:

if(Close[0] !=(Close[1]){... etc

To test this, I inserted a print statement within the IF statement and got the following output:

Line 1: Close[0]: 1665.25 Close[1]: 1665.5
Line 2: Close[0]: 1665.25 Close[1]: 1665.5
Line 3: Close[0]: 1665.25 Close[1]: 1665.5
Line 4: Close[0]: 1665.25 Close[1]: 1665.5
Line 5: Close[0]: 1665.25 Close[1]: 1665.5
Line 6: Close[0]: 1665.25 Close[1]: 1665.5

On the next "OnBarUpdate" shouldn't the value on Close[1] on Line 2 equal "1665.25" etc. Have I misunderstood how DataSeries work?

I'm trying to avoid doing the calculation on the same Close value twice in a row. Any idea on how I can achieve my goal?

Thanks

Looks like you have COBC = false. Is that correct?

Yes I do. I assume my output is justified then?

Hello daaim0,

Welcome to the NinjaTrader Support Forums!

Yes, that would be expected since with COBC set to false each incoming tick of data will cause OnBarUpdate() to be triggered. Once, the bar closes you will see the values change, otherwise while ticks of data are coming in the previous days Close will not change. You may want to print out the "CurrentBar" so that you can see when a new bar is formed for the values to change.
