I have tried to add a second vertical line with this code:
line1 = DateNum() == ParamDate("Date", "01/01/2009", 0);
line2 = DateNum() == ParamDate("Date", "31/01/2009", 0);
Plot(line1, "", colorRed, styleHistogram | styleOwnScale | styleNoLabel);
Plot(line2, "", colorBlue, styleHistogram | styleOwnScale | styleNoLabel);
Plot(Close, "Close", colorDarkGrey, styleBar);
However, it recognises only the a single line. Any suggestions?

The following AFL will allow you to pick a Date via the Parameters
menu of your chart (i.e. right click on chart and select Parameters).
A red vertical line will be drawn for that date and remain constant
across all symbols until you change the parameter value.
In the interest of providing a complete example, I've also plotted
price. You can remove the second Plot for your own chart.
line = DateNum() == ParamDate("Date", "01/01/2009", 0);
Plot(line, "", colorRed, styleHistogram | styleOwnScale | styleNoLabel);
Plot(Close, "Close", colorDarkGrey, styleBar);

something that will remain fixed on my charts no matter what chart I
am scrolling through. It would solve my problem if the layers tool had
some type of setting that enabled the highlighted dates to remain
fixed on the chart sheet or there were some type of afl that would
work. I have searched the groups database for information but didn't
find anything. Any ideas or suggestions??
