Contract change day

[Venom]

Hi, can you help me understand contract change day on CL from 02.20 to 03.20. NT used to change contract 1 day before ToS from Ameritrade.
Ameritrade changed today, I got mail from NTfew days ago that I can change contract as soon as 15.01.2020. But I changed it today on 16.01.20.
Does NT start showing 03.20 contract from 15th or from 16th of January?
Because my yesterday's candle on NT is the same as on ToS, but it used to be diffferent when contracts change, because NT usually changes contract 1 day before ToS, so normally ToS would show 02.20 for yesterday and NT would show 03.20 for yesterday, but they are same for some reason
