No nothing is 1999 in TDS. Although histdata.com goes back to 2000 for the major pairs, I'm not sure about the quality. In the Discord channel I think I noticed some confusion. Someone was talking about m1 data going back to 1999 but it seems he was looking at and showed a screenshot of metaquotes data downloaded in the MT4 history center which is not TDS.
Getting m1 metaquotes data might be useful though.
note: I only double checked the major forex pairs in TDS
