# AddLabel Show vs Not Showing w/condition

Hello, I wrote a script to calculate the dividend yield divided by the original cost basis(I.E "Cost Basis Yield") and show it as a label at the top of the chart(since portfolio data doesn't work as a column as far as I understand.

Here's the script for that:

def QuarterlyDiv = if IsNaN(GetDividend()) then QuarterlyDiv[1] else GetDividend();
def AnnualDiv = if QuarterlyDiv <> 0 then QuarterlyDiv * 4 else Double.NaN;

def costbasis = if GetAveragePrice() == 0 then Double.NaN else GetAveragePrice();

def yield = AnnualDiv / costbasis * 100;

AddLabel(1, "Cost Basis Yield: " + Round(yield, 1) + "%", Color.CYAN);

It works fine, but I want to code it so if a stock doesn't pay dividends that the whole label doesn't show(instead of N/A or -----).

I don't understand why something like this:

AddLabel(if isNan(quarterlydiv) then 0 else 1 , "Cost Basis Yield: " + Round(yield, 1) + "%", Color.CYAN);

doesn't work. It accepts the script like it's going to work, but still shows N/A on non div paying stocks

Solution

Probably should be:
Ruby:
``def QuarterlyDiv = if IsNaN(GetDividend()) then Double.NaN else GetDividend();``
it still shows "Cost Basis Yield N/A %

Probably should be:
Ruby:
``def QuarterlyDiv = if IsNaN(GetDividend()) then Double.NaN else GetDividend();``

your label is N/A because you don't have an open position in TOS, of the stock on your chart.

if there is no average price, no open position,
then this formula becomes N/A,
def costbasis = if GetAveragePrice() == 0 then Double.NaN else GetAveragePrice();

it causes the yield formula to be N/A
which shows up in the label.

change the formula to this to verify, this shows a number.
def costbasis = if GetAveragePrice() == 0 then 1 else GetAveragePrice();
