Updated FirstXminsHL.efs

[kevinmclark]

How do I modify FirstXminsHL.efs so it will work with a specific time period (0930-1000) using a 24 hour time template? Also I would like to display the values for the additional lines on the charts, similar to the original lines. Thanks.

Addditonally, is it possible to have multiple start and ending times (for example: 0930-1000 & 0000-0030) on the same chart? Thanks.

The HiLo_firstXminutes.efs that is available here will compute the High and Low based on user defined Start/End times regardless of the Time Template used (see enclosed image). You could incorporate the logic of your script into that formula.
If you are unfamiliar with programming in efs then you may want to contact one of the EFS Consultants and have them develop the study for you

Thanks for pointing me in the right direction.
