Hi,
You should not be calling array based functions from within a loop.
The first argument to PlotShapes is an array. PlotShapes will take that array and plot the indicated shape on a bar by bar basis. By calling that within a loop, you are plotting all bars at every bar, using the same shape value at each bar for every bar (that's a mouthful, but reread it a few times and hopefully it will become more clear).
If you want to build up your own array for when a shape should be drawn, change your looping code to populate the array, then call PlotShapes once after the loop, passing in your array as the first argument.
e.g.
my_array = 0;
for( i = 0; i < BarCount; i++ )
{
if( ...some true condition... )
{
my_array[i] = shapeDownTriangle;
}
else
{
my_array[i] = shapeNone;
}
}
PlotShapes(my_array, ...);
Better still would be to use array math to produce the contents of my_array and skip the loop entirely.
