Hi Pak Ku Leung,
No, they are all the same EAs. Choosing Y1, M1, W1, D1 does two things. For example, if you choose M1 then all the EAs that have not traded over the last one year are blocked from being viewed. Secondly, it zooms in on the right hand edge of the charts so you can get a better view of how the EAs are currently trading.
