size=2>Herman,
I use
OHLC composites all the time. As an example I run the following code
against a watch list to update my sector indexes
<FONT face=Arial color=#0000ff
size=2>
//creates index by sector
isym=<FONT
color=#0000ff>"~i"+<FONT
size=2>SectorID(<FONT

PMTo: AmiBrokerSubject: [amibroker] Introducing
OHLC-Composites
Most composites
display just one variable or, if they use more, they are usually
independent variables. This means that generally speaking composites do not
carry enough information to apply standard OHLC technical
analysis, like RSI, CMO, SAR, etc. to them.
<SPAN

If we could make our
Composites embody all four price arrays (OHLC), in an accurate
representation of the market they represent, then they would be much more
useful. If you have played with this type of formulas you will know that you
cannot simply create four separate OHLC composites and use these
prices in a standard OHLC bar; the resulting price bar is usually distorted to
the point it becomes useless.
<SPAN
class=120583612-09122003>
Below you'll find
one way to create OHLC-Composites. While the Open and Close probably
accurately represent the market, the High and the Low appear to have lost
their significant information (they don't change much). What is needed is a
better way to calculate the OHLC-Composite's High and Low price.
<SPAN
class=120583612-09122003>
Any constructive
help from our resident Composite-Wizards to help make the
OHLC-Composite more meaningful will be much appreciated!
