The above chart show's FXCM's DAX proxy - the GER30. We note that the orange 13-day EMA has crossed above the black 34-day EMA (green ellipse). This has put the EMAs into a bullish stack. I.e. the green 5-day EMA is above the orange 13-day EMA, and the orange 13-day EMA is above the black 34-day EMA. If the EMAs develop angle and separation to the upside, it will denote an unfolding positive momentum for the index.
