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) The "open," "high," "low," and "close" referred to are of the current bar. The prefix
ha- indicates the corresponding heikin-ashi modified values

Thanks, Brett

Hi Brett,

Here are two ways of calculating Heikin-Ashi values in MS. Both ways can only be plotted as an indicator; as far as I know, you can't plot the candlestick format without an external dll.

Method 1:

Heikin-Ashi I

HaClose:=(O+H+L+C)/4;
HaOpen:=(PREV + (Ref(O,-1)+Ref(H,-1)+Ref(L,-1)+Ref(C,-1))/4)/2;
HaHigh:=Max(Max(H,HaOpen),HaClose);
HaLow:=Min(Min(L,HaOpen),HaClose);
HaOpen; HaHigh; HaLow; HaClose

Method 2 is my favorite.

It is interesting to me for three reasons.

1. It provides insight into what Heiken-Ashi really is. It is the current day's Pivot vs. a moving average of the Pivot (Pivot = O+H+L+C)/4).
2. It is optimizable; you can optimize the lookback moving average of HaOpen (i.e., change the EMA period = 3 to OPT in a system test).
3. It shows a way to avoid using the PREV command in certain situations. This trick can be used in any MS formula where PREV is needed in the form Current Value + PREV.

Heikin-Ashi II

HaClose:=(O+H+L+C)/4;
HaOpen:=Mov(Ref(HaClose,-1),3,E);
HaHigh:=Max(Max(H,HaOpen),HaClose);
HaLow:=Min(Min(L,HaOpen),HaClose);
HaOpen; HaHigh; HaLow; HaClose
