Days to load for weekly & monthly pivots

[warrior]

Hi, what is the minimum number of days that need to be loaded in chart for correct calculation of weekly and monthly pivots? I am using std NT pivotpoints indicator. Probably different for weekly vs. monthly pivots. I want to keep number of days to minimum to save amount of time it takes to load the chart with ModHeikenAshi indicator. Also is there a custom indicator out there which doesnot look at amt of days loaded in the chart but still calculates correct weekly/monthly pivot values by looking in the database? thx.

There is no "looking at database" without populating it into a chart. That is how you look at the database. For weekly you need 5 trading days. For monthly you need 5x4 trading days give or take some depending on the month.
