I ran your code and TJ's and got exactly the same result.

Joe,
That code is TJ’s kludge to get around the need to initialize HaOpen:
HaOpen = ( Ref(HaOpen,-1) + Ref(HaClose,-1) )/2;
The correct value requires a loop:
HaOpen[0]= O[0]; HaClose[0]= C[0];
for(i=1;i<BarCount;i++)
{
HaOpen[i] = (HaOpen[i-1]+HaClose[i-1])/2;
HaClose[i] = (O[i]+C[i]+H[i]+L[i])/4;
HaHigh[i] = Max(H[i],Max(HaOpen[i],HaClose[i]));
HaLow[i] = Min(L[i],Min(HaOpen[i],HaClose[i]));
}
but inserting the correct line in your code as I’ve done below will give a
near-perfect result.
Regards,
Bob

Jack, I'll ship this to you but from here on out you must promise to look in
the program library. (:>

Also in the program library.

Subject: [amibroker] Heiken Ashi indicator
hi,
anyone has heiken ashi indicator? I found an article talking about its fomula
as below:
The heikin-ashi candlestick technique uses modified open-high-low-close
(OHLC) values and displays them as candlesticks. The modified values are
computed using these definitions:
• haClose = (O+H+L+C)/4
• haOpen = (haOpen (previous bar) + haClose (previous bar))/2
• haHigh = Maximum(H, haOpen, haClose)
• haLow = Minimum(L, haOpen, haClose)
is this the one everyone uses? if anyone has a working heiken ashi indicator
AFL file, please help uploading it or email to me.
thanks a lot
jack
