I'm not totally clear as to what you want, but if this describes
what you are after then the following AFL will do this.
Description - If we treat your 2 conditions as Cond1 and Cond2, is
what you want this? If cond1 and cond2 are up - colorgreen, if cond1
and cond2 are down - colorred, if previous bar was colorgreen and
either cond turns down - colorred, if previous bar was colorred and
either condition turns up - colorgreen. If this is what you want
then try
down = MACD()<Signal() AND MA(C,5)<MA(MA(C,5),7);
up = MACD()>Signal() 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 );
This type of code will give you increased whipsaws as either
condition changing changes color of ribbon. More informative is to
perhaps introduce a third intermediate state where the 2 conditions
don't agree. This would enable you to enter positions when both
conditions are in agreement, but exit if either condition changes.
down = MACD()<Signal() AND MA(C,5)<MA(MA(C,5),7);
up = MACD()>Signal() AND MA(C,5)>MA(MA(C,5),7);
Color = IIf(down,colorRed,IIf(Up,colorGreen, colorYellow));
Plot(10,"ribbon",Color, styleOwnScale|styleArea|styleNoLabel, -0.5,
100 );
Even more informative is to "stack the ribbons". By plotting
successive ribbons at increased widths, we can stack the ribbons so
as to see the state of each Cond separately and then the overall
state. The 3 ribbons are separated by a black "separator" line
(cosmetic only).
// cond1 ribbon
Plot(5,"Cond1", IIf( MACD()<Signal(), colorRed, colorGreen
),styleOwnScale|styleArea|styleNoLabel, -0.5, 100 );
Plot(6,"",1,styleOwnScale|styleArea|styleNoLabel, -0.5, 100 );
// Cond2 ribbon
Plot(11,"Cond2", IIf( MA(C,5)<MA(MA(C,5),7),
colorRed, colorGreen), styleOwnScale|styleArea|styleNoLabel, -0.5,
100 );
Plot(12,"",1,styleOwnScale|styleArea|styleNoLabel, -0.5, 100 );
// overall ribbon
down = MACD()<Signal() AND MA(C,5)<MA(MA(C,5),7);
up = MACD()>Signal() AND MA(C,5)>MA(MA(C,5),7);
Color = IIf(down,colorRed,IIf(Up,colorGreen, colorYellow));
Plot(20,"Overall Ribbon",Color,
styleOwnScale|styleArea|styleNoLabel, -0.5, 100 );
Hope this helps
