Hi guys

I'm a programmer newbie and don't know how to use red line and yellow line of TDI as a filter in a new EA
I know it' s a basic question but I need help.....or documents to understand how to do it
Thanks in advance

Review one of these EAs:

If that is not enough look for iCustom in this tape indicator:
