Chart Rationale

[Trader Question]

I really cannot figure out the rationale for using plain, continuous nearest contract charts sometimes, while other times
In long-term charts, they often offer contrasting indications one is in a c-wave, the other is not, one has res/supp at the envelope, the other not,....
Is there a criteria we could stick to?

Thanks for your help

You know, I don't think their is a perfect answer to this question... all the alternatives have one disadvantage or another. I end up using several charts and cross-referencing them. But let me do a little research on this and get back to you in a bit and see if I can come up with a more definitive answer.
