Ken,
I had weird display problems with your code. Price was a straight line at
the top. I basically rebuilt it and got it to work. I think maybe there were
oddball characters in there from the copy and paste. Anyhow this version has
StyleLine plots instead.
What I found was I couldnıt get the Buy arrows, but only got the Sell
Arrows! I finally discovered that your formula gives no Buy arrows if you
select, for example, ^NDX. Select INTC or AAPL and I get both types of
arrows.
Try selecting a bunch of different symbols to see if the arrows show up.
Then I would check out the Buy/Sell conditions to be sure theyıre what you
want.
Hereıs my version (only changes are to Plot statements):
AdjBar = Param("Bar",0,0,BarCount,1);
AdjZ = Param("Zig",10,0,20,.1);
//Select Current Tickers OHLC
CO = Ref(O,-AdjBar);
CH = Ref(H,-AdjBar);
CL = Ref(L,-AdjBar);
CC = Ref(C,-AdjBar);
//Select Foriegn OHLC
"Ticker " + TN = Name() ; // Show Ticker
"Index " + BI = GetBaseIndex(); //BI = BaseIndex String
FO = Ref(Foreign( BI,"O"),-AdjBar);
FH = Ref(Foreign( BI,"H"),-AdjBar);
FL = Ref(Foreign( BI,"L"),-AdjBar);
FC = Ref(Foreign( BI,"C"),-AdjBar);
//Create Trend
ZAC = Zig( CC, AdjZ );
UTrend = ZAC > Ref(ZAC, -1);
DTrend = ZAC < Ref(ZAC, -1);
//Do Cross (Create Result Arrays)
t1 = OscP( 3, 6 );
Cond1a= Cross (t1,MACD());
Cond1b= MACD()>-1 AND MACD()<0;
Cond1= Cond1a AND Cond1b;
Cond2 = MACD()>Signal()-.2;
Cond3 = Cross(0,t1);
// Select Conditions to Display.
C1 = Ref(Cond1,-AdjBar);
C2 = Ref(Cond2,-AdjBar);
C3 = Ref(Cond3,-AdjBar);
//Plot Data
Color = IIf(CO > CC, colorYellow, colorBlue);
Plot(C,Name(),color,styleThick);
Plot(FC,"Reference",colorLightGrey,styleLine|styleThick|styleOwnScale);//Plo
t Sector Index.
ZColor = IIf(UTrend, colorBlack, colorRed);
Plot( ZAC, "Zig", ZColor, styleHistogram); //Plot ZigZag Trend.
//Show Buy/Sell Arrows.
Buy = C1 AND C2 AND UTrend;
Sell= C3 AND DTrend;
Short = Sell;
Cover = Buy;
PlotShapes( shapeUpArrow * Buy, colorGreen,0,C,-20 );
PlotShapes( shapeDownArrow * Sell, colorRed,0,C,-20 );

Hi
Can anyone suggest a solution to a problem with the indicator code below.
I can am able to gain an up arrow on the chart for a buy signal but am
unable to obtain a down arrow for a sell condition no matter what I do.
What am I missing here.
Many thanks in advance.
Ken
