Investment Entry & Exit Points Line Graph
I'm trying to make a line graph that will have approximately 100 data points.
The YVALUE is the price of a stock and the XVALUE is the date for that price.
The datapoints are for purchase of the stock (entry) and sale of the stock (exit).
I would like to visually distinguish somehow between entry and exit datapoints.
When creating additional datasets to mark the datapoints with different colors (blue for entry and red for exit), each dataset also includes a line between the datapoints (each exit is linked to the next exit with a red line).
This means I end up with two different line graphs rather than a single line graph with two differently colored markers.
Is there a method to assign alternating colors to each record in my WHILE loop instead of using two while loops like I'm doing?
Is there a method to suppress the lines connecting the datapoints but still leave the datapoints?
BONUS SUPPLEMENTARY QUESTION:
Once I've got this working properly, I'd ideally like to replace the dot markers with up or down arrows. Is there a method to use images or alternate shapes for data markers?
Thanks in advance.
