Moving Average Cross plot as a line

[agent]

Hi, can anyone point me to, or possibly create an indicator which plots the 9 EMA and the 21 EMS into a single line and have the color change when the crossover happens and back again on the reverse.

Thanks in advance for the help.

Try this

input length1 = 9;
input length2 = 21;
def ema1 = expaverage(close, length1);
def ema2 = expaverage(close, length2);

plot ema = (ema1 + ema2) / 2;
ema.AssignValueColor(if ema > ema[1] then Color.GREEN else Color.RED);

plot up = if ema1 crosses above ema2 then ema else Double.NaN;
up.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
up.SetLineWeight(5);

plot dn = if ema1 crosses below ema2 then ema else Double.NaN;
dn.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
dn.SetLineWeight(5);

Hi, not sure if I am not reading it correctly but the plot line is changing but not at the 9/21 cross. Let me know what I am not seeing. thank you

The line color change is not based upon a cross occuring, but whether the combined ema is different than the combined ema 1 bar prior. The crossing arrows are based upon when the actual ema9 and ema21 crosses that you requested. This would possibly give you an idea of a change in direction, which then could possibly be confirmed by the arrow at the actual cross.

So if you want the combined line color to match the change of the arrow, this was substituted for assignvaluecolor in the above code to do that.

def emacolor = if isnan(up[1]) and !isnan(up) then 1 else if !isnan(dn) then 0 else emacolor[1];
ema.AssignValueColor(if emacolor[1] == 1 then Color.GREEN else Color.RED);

.
Here is the revised code with the new assignvaluecolor change.

input length1 = 9;
input length2 = 21;
def ema1 = expaverage(close, length1);
def ema2 = expaverage(close, length2);

plot ema = (ema1 + ema2) / 2;

plot up = if ema1 crosses above ema2 then ema else Double.NaN;
up.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
up.SetLineWeight(5);
up.setdefaultColor(color.green);

plot dn = if ema1 crosses below ema2 then ema else Double.NaN;
dn.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
dn.SetLineWeight(5);
dn.setdefaultColor(color.red);

def emacolor = if isnan(up[1]) and !isnan(up) then 1 else if !isnan(dn) then 0 else emacolor[1];
ema.AssignValueColor(if emacolor[1] == 1 then Color.GREEN else Color.RED);

Its Perfect, sorry my original request wasn't as clear. This is what I was looking for. Have a great day. Thank you.

This is simple and perfect. How do we setup a scanner for this I would like to be able to receive alerts. Thanks a bunch!
