I'm sorry but it is not a ratio. XLY closed at 145.43 XLP closed at 72.70 The difference is 72.73. This matches the number on the chart The ratio is 145.43 divided by 72.70 which is 2.00 which matches the number on my ratio chart. But if you want to call it a ratio chart, I am good with that. https://investorshub.advfn.com/uimage/uploads/2023/3/21/bnwsfx.png https://investorshub.advfn.com/uimage/uploads/2023/3/21/[iqftx.png
