I loaded your code, which looks fine, and I see no arrows. I click
backtests and then right-click on results and choose show arrows and they show
up provided I have checked Show Arrows in the parameters of the chart.
Since this is too much trouble, I then added some specific PlotShapes
to your code and they show up all the time. Can’t explain why, but this
is how I do all my arrows.
Note I have specified Graph0, but you can specify z1, z2 or any other
value you have already plotted that is on the PRIMARY axis (does not use StyleOwnScale).
In this case, Graph0 is the same as z1.
SetPositionSize( 200, spsShares
);
z1 = C*StochD(15);
z2 = TEMA(z1,3);
zt1 = Cross(C*StochD(15),TEMA(C*StochD(15),3));
zt2 = Cross(TEMA(C*StochD(15),3), C*StochD(15));
Buy = zt1==1;
Short = zt2==1;
Sell = Short;
Cover = Buy;
Plot (z1,"z1",colorBlue);
Plot (z2,"z2",colorRed);
"Closing price = " + WriteVal( Close
);
"zt1 = " + WriteVal( zt1 );
"zt2 = " + WriteVal( zt2 );
PlotShapes(shapeUpArrow
* Buy,colorGreen,0,Graph0,-10);
PlotShapes(shapeDownArrow * Short,colorRed,0,Graph0,-7);
PlotShapes(shapeHollowSmallDownTriangle * Sell,colorGreen,0,Graph0,7);
PlotShapes(shapeHollowSmallUpTriangle * Cover,colorRed,0,Graph0,7);

|
| Here's my code (modified a bit from it's initial intent because of
| my trouble with buy/sell signal arrows that STILL do not show up):
|
| SetPositionSize( 200, spsShares );
|
| z1 = C*StochD(15);
| z2 = TEMA(z1,3);
| zt1 = Cross(C*StochD(15),TEMA(C*StochD(15),3));
| zt2 = Cross(TEMA(C*StochD(15),3), C*StochD(15));
| Buy = zt1==1;
| Short = zt2==1;
| Sell = Short;
| Cover = Buy;
|
| Plot (z1,"z1",colorBlue);
| Plot (z2,"z2",colorRed);
|
| "Closing price = " + WriteVal( Close );
| "zt1 = " + WriteVal( zt1 );
| "zt2 = " + WriteVal( zt2 );
|
|
|
| So, why aren't I getting any arrows for buy and sell? I have
arrows
| on in both the indicator and main chart, I see zt1 go to 1 when a
| crossover occurs (same for zt2 when cross under). NO ARROWS??
|
| Help!

|
| ps my original code was:
|
|
| z1 = C*StochD(15);
| z2 = TEMA(z1,3);
|
| Buy = cross(z1,z2);
| Sell = cross(z2,z1);
|
| Plot (z1,"z1",colorBlue);
| Plot (z2,"z2",colorRed);
|
| ... but no arrows! arrrgh!!!
| which led to the expanded test above, which again... no arrows.
