If I have offended you, I am sincerely sorry! AmiBroker is the best program
available and I love working with it!!! Nothing wrong with AB!!!
One of the reasons the TF Functions didn't do the job in my specific case was
that my systems works with 1, 5 and 15 minute timeframes. In the chart I need
to see (and save) all the values from all the TFs plotted with 1 minute
resolution. Basically to plot the TF data as a staircase is probably the best
way to display the results for easy viewing and it's actually often so that
some TF values in a 1 minute resolutions often very closely follow a staircase
pattern- such as a Moving Average. But the AB TF Functions gives me the last
value for each period. I needed more. Now when I have all values in each period
it reveals huge amount of information when the three time frames are plotted in
one indicator with the same data resolution. For example instead of 1 value for
a 15 minute period, I have now 15 values.
Then I wouldn't like to go so far to prove my point by publish the work and
system I have been working on for months. I have a system which seems to work
rather well and I am sorry, but that one I will keep for myself. I could send
anyone who wants a screen capture of the indicator with data from 3 TFs
plotted. But such a screen capture could be faked. So I will instead give a
short explanation how easy it is to create what I was looking for. And the
reason it was easy to create, after I figured it out, was because AmiBroker is
a great program with fantastic features.
First of all, I use AB TF Functions to get the BarIndex in each TF. By having
that I can tell when each TF has a new period, and any holes doesn't matter.
Then I just go in a loop from first visible bar as many bars I need extra,
until end of the array. So in this loop when a new period is detected, I jump 1
step back and collect the values I need and the jump is equal to the TF I need
data from. Here is a part of that code:
if ( NewTFBar[i] )
{
for ( n = i; Counter < Periods AND n >= 0 ; n-- )
{
if ( NewTFBar[n] )
{
SUMA = SUMA + Close[ n - 1 ];
if ( Counter < BBPeriods - 1 )
SUMB = SUMB + Close[ n - 1 ];
Counter++;
}
}
Etc.
I hope that settles it and again it's not my intention to talk bad about
AmiBroker or to insult anyone.

Jorgen
