Quote from JackDaniel:
The ES has two sets of numbers from the previous day's trading that people use to calculate the pivots. Some people use the "all session" numbers, that is, the H/L/C from the evening, overnight in addition to the regular day session. Other people use the H/L/C just from the regular day session. This will cause the pivots to be in either exactly the same spots (if the overnight session didn't have much range) or slightly different, as they were today.
From the previous posts it looks to me like DB uses the day session numbers and ERIERAMBLER used the all session numbers. As I said, today's pivots were different from each other, but over the last month, they have varied very little between the two sets of calculations.
I've put up two charts with the different numbers up for a month or so, a few months back. The result was, you can use either numbers. It looks like an equal number of traders are using one or the other.
In other words, there doesn't seem to be a consensus as to which numbers everybody should use. For me, after my testing, I've decided to use the all session numbers and leave it at that.
Hope this helps.
