Date issue

Subject: Date Format Issue with ThinkorSwim Data Import

Hi,

I'm experiencing a date format issue when uploading data exported from ThinkorSwim into MyPnL.

My spreadsheet correctly shows today's date as 04/08/2026 (MM/DD/YYYY), however MyPnL is interpreting this as 4th August rather than 8th April, suggesting it is reading the date in DD/MM/YYYY format instead.

This appears to affect dates from the 1st through to the 12th of each month — any date where the day value could also be read as a valid month number — and as a result I am having to manually correct the dates on all affected positions after every import, which is time-consuming.

Could you please advise whether there is a date format setting within MyPnL that I can adjust, or whether this is something that can be resolved on your end?

Many thanks
