Amibroker - For loops backwards

[skinner36]

The following code works if I iterate forward through the for loop but doesn't work as illustrated below, iterating backwards.

for( i = Barcount; i > 0; i-- )
{

a = C;
}

Plot( a, "", 1,1);

I want to loop through the bars from newest to oldest, examining information from selected bars. Any idea how to do this?

Regards

Hi Skinner - not sure what you are asking here, is this post in the right area?

Skinner,

The latest bar is barcount-1, you cannot reference barcount or you will get a subscript out of range error.

Hi Skinner --

You wrote:

It looks like this is AmiBroker code. If so, the index runs from 0 to BarCount-1. So the loop control statement should read:

for (i=BarCount-1; i=0; i--)

Thanks,
Howard

Now that was stupid of me. I forgot to say that it was amibroker code. Many thanks for your help guys.

Perhaps one of the mods can amend the title inc Amibroker, so thread get the AmiBroker Attention.
