Re: [EquisMetaStock Group] How can I draw a Verical Line

Suhken,

Here's a quick idea of how it could be done in Metastock. 

In the indicator builder you would write a custom formula and lets 
call it MACD Signal. We are going to write a formula that signals the 
cross of the MACD above zero. Our formula would simply be:

{MACD Signal}
cross(MACD(),0)

This indicator is then laid onto a chart window of either a price 
plot or incicator. It is overlayed without scale...the other options 
would have been to scale with the chart or to merge. We choose 
without scale because the ouput generated by the signal would be 1 
when the signal occurs. 

What you will see on the chart is a vertical line where the MACD() 
cross over zero occurs. It would only appear in the window it resides 
in, be it price or indicator.

If you want to program a date or time you would first need to define 
that event. Roy and Jose have already done a considerable amount of 
work in that area and you might want to check their work for some 
ideas. For Fibonacci's, I'm sure Dusant can help you. What you will 
need is to define the event.

that I forgot to clearly state that. I am trying to draw vertical 
lines programatically. Suppose I calculate the datetime (I don't know 
that also how I can calculate datetime with the help of MetaStock 
language but I am sure there'd a way, would appreciate any help in 
that aspect also, was also thinking if a system call could be 
implemented using an external C/any other program if not directly 
supported by MetaStock Formula language). But before going in to 
those kind of complexities, my first basic question was if a vertcal 
line could be drawn programatically at all and if so, how. Let me 
explain a little more - if you get in to Visual Trading software of 
CMS-forex.com, you'll see a Fibonacci can be drawn along the X-axis 
(datetime for us). I was trying to work in that line (something 
similar but not exactly the same).
