The following code creates a Green or Red arrow when the price moves above the SMA AND when the MACD crosses above zero. 

I want to create a scan to scan for present day stocks and historical stocks. Is it possible to run this in the scanner and scan back say 6 months or a year ago and find companies that 
meet this criteria on a given day in history and then I can click ahead in time to see how they performed based on the arrows?  


#SMA
input size=100;
input price = close;

input length = 10;

Def SMA = Average(price,length);

Def SMAup = price >= SMA;

Def SMAdwn = price <= SMA;

#MACD

input fastLength = 8;

input slowLength = 17;

input MACDLength = 9;

input averageType = AverageType.EXPONENTIAL;

def Value = MovingAverage(averageType, close, fastLength) - MovingAverage(averageType, close, slowLength);

def Avg = MovingAverage(averageType, Value, MACDLength);

def Diff = Value - Avg;

def ZeroLine = 0;

def UpSignal = Diff > ZeroLine;

def DwnSignal = Diff < ZeroLine;

def status= if  UpSignal AND SMAup then 1 else if  DwnSignal AND SMAdwn then 2 else status[1];
plot bullish = UpSignal AND SMAup and status[1]==2;

bullish.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);

bullish.SetDefaultColor(Color.UPTICK);

bullish.SetLineWeight(3);

plot bearish = DwnSignal AND SMAdwn and status[1]==1;

bearish.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);

bearish.SetDefaultColor(Color.DOWNTICK);

bearish.SetLineWeight(3);

#addOrder(OrderType.sell_TO_CLOSE, DwnSignal[-1] AND SMAdwn[-1] and #status==1,close[-1],size,color.red,color.DOWNTICK ,"SELL" );
