Pine Script failed to plot some data

Question

I'm trying to plot some data in pine script, some data failed to plot; here is the script

// This source code is subject to the terms of the Mozilla Public License 2.0 at https://mozilla.org/MPL/2.0/ // © subikshababu

//@version=5
indicator("Gain Loss Spread", shorttitle = "GLS")
Up=close>open
Down=close<open
int datapoints=input.int(defval = 3,title="total datapoints to check",minval = 1,maxval = 512)

meangain=Up? ta.sma((close[datapoints]+ta.change(close,datapoints)),datapoints):na
meanloss=Down?ta.sma((close[datapoints]-ta.change(close,datapoints)),datapoints):na

meanpopulation=ta.sma(close,datapoints)

gainlossspread=(meangain-meanloss)+close // to be plot

//RS=meangain/meanloss
//RSI=100-(100/1-RS)// to be plot

plot(meangain,color = color.green)
plot(meanloss,color = color.red)
plot(gainlossspread,color = color.blue,style = plot.style_circles) //not ploted?
plot(meanpopulation,color = color.aqua,linewidth = 2)
//plot(RSI) // not plotted

the script plots this

What is not plotting?

meangain will only have a valid number if Up is true.
meanloss will only have a valid number if Down is true.

Up and Down are the opposites of each other so they cannot be true at the same time.

You calculate gainlossspread as gainlossspread=(meangain-meanloss)+close. Since either meangain or meanloss is na on a given bar, the result also becomes na. THat's why it is not plotting anything.

But the script is plotting mean gain and mean loss for every bar; i will add a snap shot of the indicator to my question; i'm confused

No, it does not. See my edit. I have also added a screenshot. You see a continuous line but that is because Tradingview connects two dots together. But in between, you have na values. Just move your mouse over the chart and observe the plot values.

Gratse, i changed plot style now only one is ploted

i used ta.valuewhen for gainlossspread calculation; i added close value as scaling

indicator("Gain Loss Spread", shorttitle = "GLS",overlay = true)
Up=close>open
Down=close<open
int datapoints=input.int(defval = 3,title="total datapoints to check",minval = 1,maxval = 512)

meangain=Up? ta.sma((close[datapoints]+ta.change(close,datapoints)),datapoints):na
meanloss=Down?ta.sma((close[datapoints]-ta.change(close,datapoints)),datapoints):na

meanpopulation=ta.sma(close,datapoints)
//bolinger band
meanstdev=ta.stdev(meanpopulation,datapoints,false)
hiband=meanpopulation+(meanstdev*3.619)
lowband=meanpopulation-(meanstdev*3.619)

gainlossspread=(ta.valuewhen(Up,meangain,1)-ta.valuewhen(Down,meanloss,1))+close // to be plot

plot(meangain,color = color.aqua,style = plot.style_circles,linewidth = 3)
plot(meanloss,color = color.fuchsia,style = plot.style_cross,linewidth = 3)
plot(gainlossspread,color = color.blue,linewidth = 2) //not ploted?
plot(meanpopulation,color = color.aqua)
plot(hiband,color = color.black)
plot(lowband,color = color.black)

//end
