Convert Future Bar Repainter to a Current Bar Non-Repainter

[Vinnertrade]

Can someone please help create a scanner and watchlist column for the following indicator?

I understand that the indicator references future candles, which are not supported in Thinkorswim scanners. I am looking for a scanner-compatible version that works only with confirmed/current and historical bars.

Desired scanner behavior​

• A ticker should appear in the scan when a buy signal is triggered.
• It should remain in the scan results until a sell signal is triggered.
• Conversely, once a sell signal occurs, the ticker should no longer appear in the buy-signal scan.

Desired watchlist column​

I would also like a custom watchlist column that displays:

• The current signal state: Buy, Sell, or Neutral/Blank.
• The price at which the most recent active signal was triggered—for example, the entry price from the latest buy signal.

The key requirement is that the scan retains symbols after the original buy bar, rather than showing them only on the exact bar where the buy signal occurs.

input signalOffsetFactor = 0.20;

def signalOffset = Average(TrueRange(high, close, low), 9) * signalOffsetFactor;
plot Data = hlc3;

def triggerSell = If(If(close[-1] < high, 1, 0) and (hlc3[-2] < close[-1] or hlc3[-3] < close[-1]), 1, 0);

def triggerBuy = If(If(close[-1] > low, 1, 0) and (hlc3[-2] > close[-1] or hlc3[-3] > close[-1]), 1, 0);

rec buySellSwitch = If(triggerSell, 1, If(triggerBuy, 0, buySellSwitch[1]));

def thirdBarClosed = If(IsNaN(hlc3[-3]), 0, 1);

plot SBS = If(triggerSell and thirdBarClosed and !buySellSwitch[1], high + signalOffset, If(triggerBuy and thirdBarClosed and buySellSwitch[1], low - signalOffset, Double.NaN));

SBS.SetStyle(Curve.FIRM);
SBS.SetPaintingStrategy(PaintingStrategy.LINE_VS_POINTS);
SBS.SetLineWeight(2);

SBS.AssignValueColor(if triggerSell then
if thirdBarClosed then
#UpPos
CreateColor(255, 0, 0) else
#UpNeg
CreateColor(255, 0, 0)
else if triggerBuy then
#DnPos
CreateColor(0, 255, 0) else
#DnNeg
CreateColor(0, 255, 0));

plot BuyArrow =
    If(triggerBuy and thirdBarClosed and buySellSwitch[1],
       low - signalOffset,

BuyArrow.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
BuyArrow.SetDefaultColor(Color.GREEN);
BuyArrow.SetLineWeight(2);

SellArrow.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
SellArrow.SetDefaultColor(Color.RED);
SellArrow.SetLineWeight(2);

AddChartBubble(

    "B " + AsPrice(close),
    Color.GREEN,
    no
);

AddChartBubble(

    Color.RED,
    yes
