Hi Andre,
I don't know about in ALF, but in AFL <vbg> it's certainly possible and easy.
I'm assuming you want the entire chart to have a different color when the
condition is true and another color when false, rather than just the indicator
changing color. So you can try the following:
XX = C; // substitute your value here
Indicator1 = MA(c, 5);
Indicator2 = MA(c, 20);
Indicator3 = MA(c, 50);
Indicator1_Color = colorblue;
Indicator2_Color = colorred;
Indicator3_Color = colorplum;
plot(c, "CLOSE", colorblack, stylecandle);
Plot(Indicator1, "Indicator 1", Indicator1_color, styleline );
Plot(Indicator2, "Indicator 2", Indicator2_color, styleline );
Plot(Indicator3, "Indicator 3", Indicator3_color, styleline );
Background1_color = colortan;
Background2_color = colorrose;
Cond1 = indicator3 > XX;
cond2 = indicator3 < XX;
Plot(100, "Close vs Indicator 3",
iif(cond1, colortan,
iif(cond2, colorrose,
colordefault )), styleownscale|stylearea|stylenolabel|stylenotitle, 0 ,
100, 0, -5);
I wrote the above on the fly (didn't write it within the formula editor),
however it should work fine unless there is a word-wrap issue. Let me know if
this is what you want. For demonstration purposes I simply made the indicators
to be moving averages with some default periods and the value the close of the
instrument. Substitute your own value for XX and indicators for the MAs.
Similarly you may pick your own colors to suit you. Didn't bother to
parameterize anything as I don't know what you are really doing or what you are
trading.

Subject: [amibroker] Help Needed with formula
Hi Guys,
I need to know if the following is possible in ALF.
I have 3 indicators and a price chart on my screen. When the bottom indicator
drops below a specified value, I would like to highlight in colour this area,
however, the colour must extend through the other two indicators and over the
price chart.
Does anyone have a clue how to do this?
cheers
Andre
