-### How can I get the resolution in milliseconds from a string in the `input.resolution` or `timeframe.period` format?
-This code presents two ways to go about it. The second method should be preferred, as it is more reliable than the first, which breaks when intervals between bars are irregular, which can happen for many reasons.

 ### Is it possible to use `security()` on lower intervals than the chart's current interval?
