As a guide for the ES, if the 16:30 pm est open is on the opposite side of the daily pivot as it did today, from the 9:30 am est open (splitting the pivot) this usually results in a move back to the 16:30 open within the same day or 48 hour period.
If you are receiving short signals and you have this guide appear, it is a nice exit target to have in mind and possibly can offer you a more profitable exit than your trade signal.
There is a lot you can deduct from this guide, even if it fails.
Side Note: there is a nice little gap on the ES full session charts at 1056 level around 17:00 pm est. Add this gap to the pivot being split and any rally we "may see", even if its a multi-day, will most likely revert back to at least 1056....now I do not execute trades off of this but I do like matching my signals that execute trades around this...so I become extra aware of short signals.
