What is an Array?

It's amazing what a good night's sleep does for a little perspective.
Of course these functions only look back from the right edge of the
chart - and do not produce full arrays. Thus, they are of very little
use.
That will teach me to try to be creative at 1 in the morning

Interesting. I've often wondered how to do that.
I have created a function that can be called based on this code. I
have quickly checked the results and think it works as intended.
It is 1 based - not zero based. To calculate the 4th Highest Close -
pass C to array etc.
|*function* NextHiRank ( array, Lookback, element )
// to get 4th Highest High in last 10 periods call NextHiRank (H,10,4)
{
element = *Min*(Lookback, element)-1;
bi = *BarIndex*();
a = *LastValue*( bi );
b = a - Lookback;
z = *IIf*( bi >= b, array, *Null* );
*for* ( i = b;i <= a;i++ )
{
*for* ( j = i + 1;j <= a;j++ )
{
*if* ( z[i] < z[j] )
{
temp = z[i];
z[i] = z[j];
z[j] = temp;
}
}
}
*return* z[b + element];
}|
Based on the same logic - here is the NextLoRank function.
|*function* NextLoRank ( array, Lookback, element )
{
element = *Min*(Lookback, element)-1;
bi = *BarIndex*();
a = *LastValue*( bi );
b = a - Lookback;
z = *IIf*( bi >= b, array, *Null* );
*for* ( i = b;i <= a;i++ )
{
*for* ( j = i + 1;j <= a;j++ )
{
*if* ( z[i] > z[j] )
{
temp = z[i];
z[i] = z[j];
z[j] = temp;
}
}
}
*return* z[b + element];
}|
Thanks to Inquisitive Voyager for a great idea.

I want to find out the three highest highs for the past 100
periods. Highest give only the top value, how can I get the next
highest value and the next?
Thanks,
