Moving Average Colored EMA/SMA

This script will give you the ability to put an EMA and/or SMA on the chart that changes color based upon the direction. Default at startup is EMA visible and SMA hidden. When the MA is moving up, it is green. When the MA is moving down, it is red. You can change the color to whatever you like.

@vitalycool, You can do that with most indicators. Just right click on the line and setup an alert.

This is really great, thanks for making it available.

I'm trying to apply the idea to this HPotter's ADV Line indicator, but can't figure it out. Any chance you could help?
This is the code:

study(title="Advance/Decline Volume Line", shorttitle="ADV Line", overlay = false)
AdvSymbolVolume = input(title="Advancing Volume Symbol", type=symbol, defval="USI:UVOL")
DecSymbolVolume = input(title="Declining Volume Symbol", type=symbol, defval="USI:DVOL")
Resolutin = input(title="Resolution", type=resolution, defval="D")
xASVValue = security(AdvSymbolVolume, Resolutin, close)
xDSVValue = security(DecSymbolVolume, Resolutin, close)
NetADV = xASVValue - xDSVValue
nRes = nz(nRes, 0) + NetADV
plot(nRes, color=green, title="ADV Line", style=line)

Many thanks in advance.

@OTMRob, At first glance you are trying to create a new value that is referencing itself (nRes): nRes = nz(nRes, 0) + NetADV

@repo32, thanks for the reply, sorry to take so long to reply myself, I hadn't noticed the alert...
I'm not familiar enough with pine to understand what you're saying there about the self referencing value, unfortunately, but would love to try to understand if you have the time to explain. This is @HPotter 's script.

I would be happy to pay for the script above with code that changes color based upon the direction added in.

@OTMRob, Please post the link to the script.

Thanks in advance.

@OTMRob, Just remove the last line from his script and add the following:

UnRes = nRes > nRes
DnRes = nRes < nRes
mycolor =UnRes ? green : DnRes ? red:blue
plot(nRes, color=mycolor, title="ADV Line", style=line)

@repo32, Not sure why the is being removed from the end of the first two lines.
