DR/IDR - How to Resolve an Error with Sunday Evening Calculation

View Count: 145

Using some Simple Studies & Spreadsheet Formulas, I've created the DR/IDR lines & 1x Std Deviation for the ADR session only. Cht file attached below.

The ADR session calculation is based on price action between 19:30 till 20:29:59

Everything works perfectly on All days, EXCEPT for certain Sundays, when the calculations are based on Sunday evening data (19:30 - 20:29:59 NY time).

Bizarrely, certain Sundays appear to show the calculations correctly (e.g. 16.03.2025), but on other Sundays, the line calculations are off (e.g. 9.03.25)

This happens on all symbols, both Forex pairs and Futures (USDJPY, AUDUSD, 6J, etc.)

What am I missing? Please help.

We need more information on what exactly is incorrect. We do not see anything that stands out when we look at the lines for March 9, 2025. Please get us an image with any markups on it showing the particular problem and explaining it. Refer to the following for how to get us an image:

Thanks. Sharing 3 examples below with screenshots & markups

A) Sunday 9 March DR/IDR Lines NOT plotting correctly (& skewing subsequent calculations that are based on those lines)
B) Sunday 16 March lines working fine
C) Other Days (Mondays - Thursdays) - Calculation working perfectly

Another Sunday example where the calculation is NOT working correctly is Sunday 23 February.

Please note: These errors are not confined only to one pair (USDJPY in this example). Similar errors occur on certain Sundays on Futures as well (E.g. 6J) and on other Forex pairs (e.g. AUDUSD). I can share those screenshots if need be.

Please guide on where the error seems to be occurring. Thanks


Update: The same error occurred yesterday too (Sunday 23 March 25 19:30 - 20:30) on all the symbols I checked (NQ, ES, 6E, USDJPY, AUDUSD, 6J)

When we open your Chartbook everything shows correctly for us. Attached is an image of what we see for March 9, 2025.

Therefore, we do not know what is occurring or why it is occurring in your case.

You would need to strip things down to the simplest studies that show what you are seeing and determine why those studies are doing what you see.

Thanks. Magically, just upgrading my Sierra to the latest version fixed this somehow.

Appreciate the help.
