Heikin Ashi Close for Today's Candle is
(L + (XAVGO3.1 + XAVGH3.1 + XAVGL3.1 + XAVGC3.1) / 4 - ABS(L - (XAVGO3.1 + XAVGH3.1 + XAVGL3.1 + XAVGC3.1) / 4)) / 2

What is the formula for the 10 and the 20 exponential MA of the Heikin Ashi candle Close?

Your formula is actually for the Heikin-Ashi Low. A formula for the Heikin-Ashi Close would be:

(O + H + L + C) / 4

A 10-Period Exponential Moving Average of this would be:

(XAVGO10 + XAVGH10 + XAVGL10 + XAVGC10) / 4

A 20-Period Exponential Moving Average of this would be;

(XAVGO20 + XAVGH20 + XAVGL20 + XAVGC20) / 4

A 10-Period Exponential Moving Average of the Heikin-Ashi Low would be much longer:

(XAVGL10 + (XAVG(XAVGO3.1,10) + XAVG(XAVGH3.1,10) + XAVG(XAVGL3.1,10) + XAVG(XAVGC3.1,10)) / 4 - .181980276277401 * (ABS(L - (XAVGO3.1 + XAVGH3.1 + XAVGL3.1 + XAVGC3.1) / 4) + 9 / 11 * (ABS(L1 - (XAVGO3.2 + XAVGH3.2 + XAVGL3.2 + XAVGC3.2) / 4) + 9 / 11 * (ABS(L2 - (XAVGO3.3 + XAVGH3.3 + XAVGL3.3 + XAVGC3.3) / 4) + 9 / 11 * (ABS(L3 - (XAVGO3.4 + XAVGH3.4 + XAVGL3.4 + XAVGC3.4) / 4) + 9 / 11 * (ABS(L4 - (XAVGO3.5 + XAVGH3.5 + XAVGL3.5 + XAVGC3.5) / 4) + 9 / 11 * (ABS(L5 - (XAVGO3.6 + XAVGH3.6 + XAVGL3.6 + XAVGC3.6) / 4) + 9 / 11 * (ABS(L6 - (XAVGO3.7 + XAVGH3.7 + XAVGL3.7 + XAVGC3.7) / 4) + 9 / 11 * (ABS(L7 - (XAVGO3.8 + XAVGH3.8 + XAVGL3.8 + XAVGC3.8) / 4) + 9 / 11 * (ABS(L8 - (XAVGO3.9 + XAVGH3.9 + XAVGL3.9 + XAVGC3.9) / 4) + 9 / 11 * (ABS(L9 - (XAVGO3.10 + XAVGH3.10 + XAVGL3.10 + XAVGC3.10) / 4) + 9 / 11 * (ABS(L10 - (XAVGO3.11 + XAVGH3.11 + XAVGL3.11 + XAVGC3.11) / 4) + 9 / 11 * (ABS(L11 - (XAVGO3.12 + XAVGH3.12 + XAVGL3.12 + XAVGC3.12) / 4) + 9 / 11 * (ABS(L12 - (XAVGO3.13 + XAVGH3.13 + XAVGL3.13 + XAVGC3.13) / 4) + 9 / 11 * (ABS(L13 - (XAVGO3.14 + XAVGH3.14 + XAVGL3.14 + XAVGC3.14) / 4) + 9 / 11 * (ABS(L14 - (XAVGO3.15 + XAVGH3.15 + XAVGL3.15 + XAVGC3.15) / 4) + 9 / 11 * (ABS(L15 - (XAVGO3.16 + XAVGH3.16 + XAVGL3.16 + XAVGC3.16) / 4) + 9 / 11 * (ABS(L16 - (XAVGO3.17 + XAVGH3.17 + XAVGL3.17 + XAVGC3.17) / 4) + 9 / 11 * (ABS(L17 - (XAVGO3.18 + XAVGH3.18 + XAVGL3.18 + XAVGC3.18) / 4) + 9 / 11 * (ABS(L18 - (XAVGO3.19 + XAVGH3.19 + XAVGL3.19 + XAVGC3.19) / 4) + 9 / 11 * (ABS(L19 - (XAVGO3.20 + XAVGH3.20 + XAVGL3.20 + XAVGC3.20) / 4) + 9 / 11 * (ABS(L20 - (XAVGO3.21 + XAVGH3.21 + XAVGL3.21 + XAVGC3.21) / 4) + 9 / 11 * (ABS(L21 - (XAVGO3.22 + XAVGH3.22 + XAVGL3.22 + XAVGC3.22) / 4) + 9 / 11 * (ABS(L22 - (XAVGO3.23 + XAVGH3.23 + XAVGL3.23 + XAVGC3.23) / 4) + 9 / 11 * (ABS(L23 - (XAVGO3.24 + XAVGH3.24 + XAVGL3.24 + XAVGC3.24) / 4) + 9 / 11 * (ABS(L24 - (XAVGO3.25 + XAVGH3.25 + XAVGL3.25 + XAVGC3.25) / 4) + 9 / 11 * (ABS(L25 - (XAVGO3.26 + XAVGH3.26 + XAVGL3.26 + XAVGC3.26) / 4) + 9 / 11 * (ABS(L26 - (XAVGO3.27 + XAVGH3.27 + XAVGL3.27 + XAVGC3.27) / 4) + 9 / 11 * (ABS(L27 - (XAVGO3.28 + XAVGH3.28 + XAVGL3.28 + XAVGC3.28) / 4) + 9 / 11 * (ABS(L28 - (XAVGO3.29 + XAVGH3.29 + XAVGL3.29 + XAVGC3.29) / 4) + 9 / 11 * (ABS(L29 - (XAVGO3.30 + XAVGH3.30 + XAVGL3.30 + XAVGC3.30) / 4) + 9 / 11 * (ABS(L30 - (XAVGO3.31 + XAVGH3.31 + XAVGL3.31 + XAVGC3.31) / 4) + 9 / 11 * (ABS(L31 - (XAVGO3.32 + XAVGH3.32 + XAVGL3.32 + XAVGC3.32) / 4) + 9 / 11 * (ABS(L32 - (XAVGO3.33 + XAVGH3.33 + XAVGL3.33 + XAVGC3.33) / 4) + 9 / 11 * (ABS(L33 - (XAVGO3.34 + XAVGH3.34 + XAVGL3.34 + XAVGC3.34) / 4) + 9 / 11 * ABS(L34 - (XAVGO3.35 + XAVGH3.35 + XAVGL3.35 + XAVGC3.35) / 4)))))))))))))))))))))))))))))))))))) / 2

Thanks again Bruce. Have a great day!

How would one write (or create) an EasyScan that looks for the 10 Heikin Ashi EMA & 20 Heikin Ashi EMA crossover? Both to the upside and to the downside? I tried using "Create Scan Condition" but only one of the HA EMA's comes up and not the other one. Thoughts?

Are both of the exponential moving averages plotted on the chart? You definitely don't want to be creating a Condition Formula for this unless absolutely necessary.
