If you open the full res, you will find a tiny fraction difference between the three:
Uniswap.org: 35.199
Uniswap.vision: 35.19849
Chartex: 35.1799
I think the different data that shown is normal, AFAIK, the gap because API used by uniswap vision and chartex have different speed to grab data. something normal. but if uniswap vision and chartex have more higher than uniswap.org, something strange happens or it can be manipulated data. CMIIW.
