Label that shows SPY DIA QQQ and their % difference from yesterday?

Hello, I made 3 labels to have the SPY DIA and QQQ on top of my charts, which is really helpful for me, but I was wondering if there's way to have the % difference from yesterday for each of those in the same label or in another one right next to it. Any help would be immensely appreciated.
 
Post what you have and then we can help you add on top of it.
Extremely simple, this is just the only thing that I have:

Code:
def SPY = Close ("SPY");
def QQQ = Close ("QQQ");
def DJI = Close("DIA");
AddLabel(Yes,"SPY: " + SPY, Color.Blue);
AddLabel(Yes,"QQQ: " + QQQ, Color.Blue);
AddLabel(Yes,"DJI: " + DJI, Color.Blue);

So it would be great just to have the % change from yesterday for each of those. Really new into coding so I have no idea on how to do this. I have been reading a lot trying to figure out, but I've only been able to find ways to display the % difference for the ticker of the chart that's showing.

TIA!
 
the current price compared to the close from the previous day would be what would help me out the most

I came up with this. I tested it in OnDeMand, since today's a Saturday, and it at least shows percentages. I have not double-checked for accuracy. Hope it fits your use case (or, the use case of the next person that stumbles upon this thread)

Note: I included the aggregation period because the comparison might break down at lower time frames (imagine looking at a 5-minute chart, when you want to know how well SPY did since yesterday, not since 5 minutes ago). Of course, adding the aggregation period then means this label won't do you any good on weekly or monthly charts.

def SPY = close("SPY", period = AggregationPeriod.DAY);
def QQQ = close("QQQ", period = AggregationPeriod.DAY);
def DIA = close("DIA", period = AggregationPeriod.DAY);

AddLabel(yes, "SPY: " + SPY + " | " + AsPercent((SPY - SPY[1])/SPY[1]), Color.BLUE);
AddLabel(yes, "QQQ: " + QQQ + " | " + AsPercent((QQQ - QQQ[1])/QQQ[1]), Color.BLUE);
AddLabel(yes, "DIA: " + DIA + " | " + AsPercent((DIA - DIA[1])/DIA[1]), Color.BLUE);
