That’s a proof?

Could you please elaborate?

I must have missed where you proved that

HaOpen =AMA(Ref( HaClose, -1),0.5);

Heikin Ashi was published as TASC tip and it does not require loop. AMA can do the same

in fewer lines

USING THE HEIKIN-ASHI TECHNIQUE

In "Using The Heikin-Ashi Technique" article Dan Valcu presents a new candlestick charting technique based on modified open-high-low-close values. The charts presented in the article can be easily reproduced using AmiBroker Formula Language. Listing 1 shows ready-to-use code that produces modified candlestick chart. Listing 2 shows the code for haDiffCO indicator presented in the article.

LISTING 1

HaClose = (O+H+L+C)/4;
HaOpen =AMA(Ref( HaClose, -1),0.5);
HaHigh =Max( H, Max( HaClose, HaOpen ) );
HaLow =Min( L, Min( HaClose, HaOpen ) );

PlotOHLC( HaOpen, HaHigh, HaLow, HaClose,"Modified "+Name(), colorBlack, styleCandle );

LISTING 2

HaClose = (O+H+L+C)/4;
HaOpen =AMA(Ref( HaClose, -1),0.5);
HaHigh =Max( H, Max( HaClose, HaOpen ) );
HaLow =Min( L, Min( HaClose, HaOpen ) );

HaDiffCO = HaClose - HaOpen;

per =Param("MA Periods",3,3,50,1);
Plot( HaDiffCo,"HaDiffCO", colorRed );
Plot(MA( HaDiffCo, per ),"MA("+per+")", colorBlue );

The screen shot in Figure 1 shows the daily SP-500 modified candlestick chart (upper pane), classic candlestick chart (middle pane) and HaDiffCO indicator with 3 day moving average (lower pane).

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

Also in the program library.

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
