Hi, I would like to create a plot for the white arrows on the DAILY Chart when these conditions are met
1. The Weekly DPO line is below the Zeroline
2. 10Week EMA is below 30Week EMA
3. Weekly Close is greater than previous week close
Overview,
On left chart, the white arrows near the 4 white dotted lines are invalid because, the DPO line is above zeroline, marked on the Weekly chart.
The only valid WHITE arrow is being marked by the Blue line.

I am not sure if this is possible, and like to seek some help.

Thanks

#white arrow plot
Plot Trend1 = MovAvgExponential(close, 10);
Trend1.AssignValueColor(if close > Trend1 then Color.GREEN else Color.RED);
Trend1.SetLineWeight(1);
Plot Trend2 = MovAvgExponential(close, 30);
Trend2.AssignValueColor(if close > Trend2 then Color.GREEN else Color.RED);
Trend2.SetLineWeight(2);
Plot white = close > Trend1 and close<trend2 and Trend2 > Trend1;
white.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
white.SetLineWeight(3);
L5.AssignValueColor(COLOR.white);

input Num_Dev_Up = +0.8;

# Fuel Cell (MACD) inputs

input MACDScaling = 50; # Enlarge or shrink FuelCell size.
input MACDWidth = 3; # Width of individual FuelCell elements.
input MACDColors = {default "Cyan_Only", "Cyan_Magenta", "Red_Green"};
input level =-1;

plot Zeroline = 0;
ZeroLine.SetDefaultColor(GetColor(5));

plot DPO = price - Average(price[DPO_length / 2 + 1], DPO_length);
DPO.DefineColor("Highest", Color.Yellow);
DPO.DefineColor("Lowest", Color.Light_Red);
DPO.AssignNormGradientColor(colorNormLength, DPO.color("Lowest"), DPO.color("Highest"));

Yes, it's possible.

However, when you access higher timeframes they cause the smaller periods within those timeframes to continue updating until the higher timeframe period ends, commonly referred to as "repainting". For instance, on Monday you may have no arrow on the daily chart because the weekly conditions are not met. On Tuesday they are met and an arrow appears on both Monday and Tuesday. On Wednesday conditions are no longer met so the arrows are gone. Thursday conditions are met again and now you have arrows on Mon, Tue, Wed, Thu. This back and forth can continue until the close of the week on Friday.

You can access higher timeframes by specifying the aggregation period when you refer to prices. For instance, to get the 10 week EMA you can write:

Ruby:
def weekEma10 = ExpAverage(close(period=AggregationPeriod.WEEK), 10);

For each of your conditions based on weekly data you need to either update the code to accept the period as an input parameter or make a new version of the code that hard codes the period. This can be done either as new individual scripts or you could copy all of the code into your main script and do it there.

After taking careful consideration of the very good comments by @Slippage, see if this helps in your analysis.
