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 Best Regards Rick Osborn ________________________________ From: Rick Osborn <ri...@rogers.com> To: amibroker@yahoogroups.com Sent: Sat, August 7, 2010 1:06:46 AM Subject: Re: [amibroker] Multiple Higher Highs in Amibroker? 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. functionNextHiRank ( 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; } } } returnz[b + element]; } Based on the same logic - here is the NextLoRank function. functionNextLoRank ( 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; } } } returnz[b + element]; } Thanks to Inquisitive Voyager for a great idea.
