RE: [amibroker] StaticVar Application: Measure price changes between clicks

["Herman van den Bergen" <psytek@xxxxxxxx>]

Thank 
you  Tomasz, good point. However the code is intended to illustrate a 
possible use of Static vars. For example, in my personal application 
I use this code to collect sequential prices for further analysis 
and tabling on the chart. I think that would be difficult (impossible?) to 
do without Static vars :-)

  Hello,
   
  An easier solution would be using BeginValue and 
  EndValue functions

    Application: Measure price changes between clicks
    
    This function is 
    handy to measure the price difference between two points, click on the first 
    and then the second and read the difference. I use it to get an idea of 
    indicator profitability by clicking on various points on my charts. It 
    works under Real Time Refresh conditions. You can modify this to work 
    horizontally to measure distances between bars.
