RE: [amibroker] Loop thru past N bars

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

Perhaps:

Str = "";
nBarsToLoopThrough = 10;
for (n=BarCount-1; n >= BarCount - nBarsToLoopThrough; n--)
{
Str = Str + NumToStr(n,1.0,False)+"\n";
}
str;

Not sure what you mean with "I want it to start from the 1st bar in the
chart."....you are starting at the end and count backwards. Perhaps this:

Str = "";
nBarsToLoopThrough = 10;
for (n=BarCount - nBarsToLoopThrough-1; n< BarCount; n++)
{
Str = Str + NumToStr(n,1.0,False)+"\n";
}
str;

Copy to a new Indicator, Apply, Open your Interpretation screen, and click
on your chart to see a list of array elements addressed by the loop.

best regards,
herman

Subject: [amibroker] Loop thru past N bars




Hi,
I am trying to write a for loop to loop thru the past N bars for each
backtesting cycle.

I did something like this:

lastbar = LastValue(BarIndex());

for (n=lastbar; n>=lastbar-20; n--)
{
check close[n], etc.
}

But it seems that this loop is only run once during the auto analysis
starting at the very last bar of the chart. I want it to start from
the 1st bar in the chart.

Thanks,
Steven.
