[EquisMetaStock Group] Re: Heikin Ashi and PREV function

["jawjahtek" <jawjahtek@xxxxxxxxx>]

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:

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.

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

close (OHLC) values and displays them as candlesticks. The modified

and "close" referred to are of the current bar. The prefix
