 The formula for a DEMA is:

(2*n-day EMA)-(n-day EMA of EMA)

So, the following formula would return True if the 6-Period Simple Moving Average crossed up through the 5-Period DEMA:

AVGC6 > 2 * XAVGC5 - XAVG(XAVGC5,5) AND AVGC6.1 <= 2 * XAVGC5.1 - XAVG(XAVGC5.1,5)

Your formula would depend on your specific settings and the direction of the crossover. You may wish to review the following:
