Graham,
EMA is also an indicator. It has trendlines, for example, like any
plotted line.
As I wrote to RSIsup/res, trendlines value for tomorrow are ALREADY
known today.
You may, consequently, anticipate through trendlines the next bar
EMAsupport and EMAresistance and then translate it into Close terms.
Since EMA is smoother than Close itself, EMA trendlines are tighter.
I will give the full code later, now I try [unsuccessfully] to buy !!
