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. (:>

HaHigh = Max( H, Max( HaClose, HaOpen ) );

HaLow = Min( L, Min( HaClose, HaOpen ) );

Title = "\n" + "" + Name() + ", " + Interval(2) + ", " + Date() + "\n";

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
