Sorry for a silly suggestion, but have you used Foreign to get the MACD etc
for the S&P500 and ASX500. I assume this is where the signals are required
to come from?
Another suggestion, in case the above is a wrong assumption, use plotshapes
to demonstrate the crossing points of the MACD/Signal and the MA's on a
chart. It may just be that the MACD etc used in the calculation may be
different to that displayed on the chart
Cheers,
Graham

Thanks indeed for your efforts Andrew,
Also thanks to Graham,Mr Valley,Corey and Anthony.
To explain my requirements more fully;
One of my portfolios 'Position Trades' the ASX (Australian Stock
Exchange).
The overiding condition of entering any trade is that both the S&P500
and the ASX500 are displaying an uptrend.
My definition, in this instance, of an uptrend is;
MA(C,5) > MA(MA(C,5),7).
After some investigation I figured that adding;
MACD > an 18pd SIGNAL LINE,
to my definition would improve the results. The use of an 18pd signal
line will reduce whipsaws to an acceptable level.
I require that a color change be plotted if either condition is met.
So,my final formula (inserted in the built-in 'PRICE' indicator) is
as follows;
//MACD & MA Ribbon
down = MACD()<EMA(MACD(),18) AND MA(C,5)<MA(MA(C,5),7);
up = MACD()>EMA(MACD(),18) AND MA(C,5)>MA(MA(C,5),7);
Color = IIf(down,colorRed,IIf(Up,colorGreen, IIf(BarsSince(up)
>BarsSince(down),colorGreen,colorRed)));
Plot(10,"ribbon",Color, styleOwnScale|styleArea|styleNoLabel, -0.5, 100 );
/*xxxx end xxxx*/
IN ADDITION.
The use of this ribbon method of displaying indicators has several
benefits for a laptop user such as myself;
It is visually clear, unobtrusive and compact,
It does not 'clutter' the pane,
It allows the use of other MA lines thru 'Preferences'.
Andrews other contributions detailed below (Post 53458) lead me to
envisage several clear,compact indicators IN ONE PANE.
When I have more than three panes open on my monitor I lose
perspective.
The ability to have several visually clear indicators open in one
pane on my laptop?
I'M EXCITED!
Thanks again to all,
Regds Gerard
