Subject: RE: [amibroker] Dynamic
indicators
A
workaround would be
<SPAN
class=642142913-17042003>
<SPAN
class=642142913-17042003>c=v<FONT face=Arial color=#0000ff
size=2>;
<SPAN
class=642142913-17042003>plot(macd(12,26),"",4,1);
<SPAN
class=642142913-17042003>
of
course this fails if you need actual closing data elsewhere in the
code......

[amibroker] Dynamic indicatorsHi CS, DT and
all,I too would like dynamic (user modifyable) args tointernal
functions. For example the MACD and SIGNALfunctions work only on the Close
price. It would be a plus if user could override the default Close array
it internally uses.The function prototypes then would look like:
MACD(fastperiod = 12, slowperiod = 26, sourcearray = Close);
SIGNAL(fastperiod = 12, slowperiod = 26, signalperiod = 9, sourcearray =
Close);(here the last param was added).then such things like the
following would be possible: MACD(12,26,C) > MACD(12,26,EMA(C,
9)); or you could create the MACD for volume etc...

When we write RSI(12), we mean RSI calculated on Close, periods=12.> An
