Stable signal on watch list

How are you doing? Hope all is well.

I’m looking for a stable signal in the watch list. Let me explain.

When I’m on Watchlist and I have a 1-minute trend reversal signal, when the 1-minute candle is finished, the signal also disappears.Can you create when the signal appears,it stays until the signal reverse .

I want the red and green color in the Watch List to show several bars AFTER the signal until the signal is reversed

Can you create when the signal appears,it stays until the signal reverse .

an example of stable signal created by you:
#———- Signals Section
def upSignal = rsi > ma;
def downSignal = rsi < ma;
plot data = if upSignal then 1 else if downSignal then -1 else 0;
data.AssignValueColor(if data == 0 then Color.CURRENT else Color.BLACK);
AssignBackgroundColor(if data == 1 then Color.GREEN else if data == -1 then Color.RED else Color.CURRENT);
