Difference between"Bars ago" & "look Back"

[ju1234]

What is the difference between "Bars ago" and "Look back period".

If I understand it correctly: the look back of 3 will look for the condition (all settings in the condition left panel and right) in last 3 bars and if any of the three meet the condition it will take action. On the other hand "Bars ago=3", ONLY the parameter set in left panel of the Builder will be searched through the last 3 bars. Am I right? Thanks.

Hi ju1234,
Thanks for your post.

The 'LookBack' period sets the number of bars to look back to check for the cross above / cross below condition.

'BarsAgo' references a certain data point value of your parameters in past.

Bars ago?

For VOL if I have bars ago=3, does that mean the volume of "bar 3" or "any bar in last 3". If the former, how do i express "any bar in last 3"? Thanks.

Hi ju1234,

Thanks for posting!

This means it considers the volume that occured 3 bars ago.

For your purpose you can look into MAX() from the indicators and specify 3 as the 'Period' while using Volume from the Price data category as your input series.
