I've recently wondered which stocks in my watchlist have the greatest and lowest percentage change since the stock market "crash" in March 2020. Here's a watchlist column and label to help you identify the stock percentage change since the pandemic panic low on March 23.
For your watchlist column, be sure to set the aggregation period to D for Daily.
Watchlist column
Code:
# Stocks Percentage Change since March lows

def close_value = close(period = AggregationPeriod.DAY);
def date1 = GetYYYYMMDD() == 20200323;
def date2 = GetYYYYMMDD() == GetYYYYMMDD();
def prev = if date1 then close_value else prev[1];
def current = if date2 then close_value else current[1];
def test = Round((current - prev) / prev);
#AddLabel(yes, Concat("", test), color.orange);
AddLabel(1, "" + AsPercent(test), color.orange);

Label for your chart
Code:
# Stocks Percentage Change since March lows
# Assembled by BenTen at UseThinkScript.com
def close_value = close(period = AggregationPeriod.DAY);
input source = 20200323;
def date1 = GetYYYYMMDD() == source;
def date2 = GetYYYYMMDD() == GetYYYYMMDD();
def prev = if date1 then close_value else prev[1];
def current = if date2 then close_value else current[1];
def test = Round((current - prev) / prev);
#AddLabel(yes, Concat("Change since March's low = %", test), color.orange);
AddLabel(1, "Change since March's low = " + AsPercent(test), color.orange);
