Moving Average Last Value

[RogerC]

I'm trying to get the last value of a weighted moving average on a daily chart. I would like the last value to be represented graphically by a horizontal bar starting on the last day of the chart and then extending right.

The code below gives me an orange line for each day, but I want only the value of the last day.

# Define input parameters
input length = 20;

# Calculate moving average
plot ma = MovAvgWeighted(close, length);

# Get the last value of the moving average
def lastMAValue = GetValue(ma, 0);

# Plot the last value as a horizontal line
plot lastMAPlot = lastMAValue;
lastMAPlot.SetDefaultColor(Color.ORANGE);
lastMAPlot.SetLineWeight(2);
lastMAPlot.SetStyle(Curve.FIRM);
lastMAPlot.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);

Thanks for any suggestions.

this isn't the last bar. it has an offset of 0, so it points to the current bar.
def lastMAValue = GetValue(ma, 0);

this will find the last bar. the current has a valid price and the next bar has an error, no price data.
if (!isnan(close) and isnan(close[-1])) then

# horz_last_avg

def na =  double.nan;

# Define input parameters
input length = 20;

# Calculate moving average
def ma = MovAvgWeighted(close, length);

input show_avg_line = no;
plot avg = if show_avg_line then ma else na;

def line = if (!isnan(close) and isnan(close[-1])) then ma
else if isnan(close) then line[1]
else na;

plot z = line;
z.setdefaultcolor(color.cyan);
