    Subject: [amibroker] question about 
    symbols in chart
    
    hello,
     
    what I sometime notice is that certain symbols 
    whcih I try to put at certain places in the chart seem to change if I blow 
    up the chart and scroll through it. 
     
    My question is: is this an indication of an 
    error in the code or do I not understand how exactly Amibroker operates when 
    plotting the chart. As an example I give the code below which is part my 
    interpretation of Welles Wilders "Reaction Trend System". I give here only 
    the calculation of the "phase". This phase is added to the chart using the 
    numbers 1, 2 and 3. 
     
    Now if you make a chart of INTRADAY data (e.g. 
    the hourly data) and not plot all the data but just like 30 days and use the 
    mouse-scroll to move the chart from left to right or the other way around 
    you will notice that sometimes the numbers change. Why is that? Is it due to 
    an error in coding or is it the way Amibroker calculates the 
    chart?
     
    So maybe in general my question is: if I see 
    indicators changing in the chart when scrolling through it is this 
    immediatelly a sign that there is an error in the code?
     
    thnks, Ed
     
     
    part of the code. Note: try it using Intraday 
    data (hourly)
