I have been trying to write the time difference between the current bar and the previous 2 bars to a streamfile using streamfilewriter. I cant use Time[0] - Time [2] because I gety an error that I cant use - for Time
I cant use Time[0].subtract(Time[2]) since this gives me 0 all the time. I have looked here but could not find any thing regarding the time difference between bars.

Someone Please help.

Thanks in advance

You could try and use Time[0].Ticks - Time[2].Ticks
Then you have the different in ticks
There are 10.000 ticks in a millisecond or 10 million ticks in a second

hope this helps you

Thanks for the reply. When I tried the code to write this to an indicator or stream file writer I get the following error :

"Error on caling 'OnBarUpdate' method for Indicator 'TickTime' on bar 0: Bar Index needs to be greater/equal 0"

I am not sure how to proceed!

yeskannan,

this error will come up when you try to access a bar that is not yet present - for example trying to look back two bars on the first bar of the chart. You can prevent this by checking you have enough bars.
Depending on how far back (in this case two bars from the current bar), adding the following code at the top of OnBarUpdate should prevent the error.

Code

if (CurrentBar <= 2)
{
   return;
}

You can find additional information here.
