Identifying the first and last bar in an intraday set up

[timhan]

Hi,
I've got a strategy using 2 multi-time frames. Is there a way of knowing which bar is being called? I know I can use BarsInProgress to find out which time frame it is, but can I then find out which bar of that time frame it is?

For example, when the period is set to 1 minute, I only want to execute the code on the first and last bar of that day.

Thanks for the help, Tim.

Hello Tim,

Thank you for your post.

You would continue to use BarsInProgress. This is designed as a filter for your OnBarUpdate to let you know which bar update and what bar series it belongs to.

Lets say I have the chart set to 1 minute and added a 150 tick to the script
1 minute becomes BIP == 0 and 150 tick becomes BIP == 1

You can then use that logic to separate out your script accordingly.

Cool, so how would I identify the 5th minute bar, and the last minute bar? Is there an index.

I thought the BIP only identifies which bar the currentbar belongs to.

Tim,

You would want to most likely use GetBar() in conjunction with BarsArray
