Giving the "bars ago" option a time period, not a specific value

[Chris_GRM]

Hello Support team,

you are always very helpful, thanks for that first!

I have another question today. I want to enter long, once a close price was less the lower bollinger bond within the last 10 bars AND the EMA with a period of 5 cross above the EMA with a period of 14 (for example)

To enter long when the 2 EMA cross is no problem, but for the Bollinger bond section I can only use bars ago. I want to use something like "within the last 10 bars"

Is this possible?

Thanks!

Hello Chris_GRM,

Thank you for your post.

You could do this by using CrossBelow with a lookback of 10. So, on the right, I'd select the close price and on the left the lower Bollinger band, and use CrossBelow with the lookback set to 10. What this is basically doing is looking for the close price to have crossed below the Bollinger any time within the prior 10 bars. I'm attaching a very simple example I've set up in the Strategy Builder.

Please let us know if we may be of further assistance to you.
