moving average that changes colors

[rtwave]

hello everyone,


i have been trying to code an indicator that will change colors according to two different data sets but i have run into a lot of trouble with nt's regions, variables, data sets and other minutiae.

i'd like to plot a 9 period sma. this 9 period sma would be plotted orange if a 10 period sma and an 18 period sma are both rising. it would be plotted purple if the 10 period and 18 period sma's are both falling and it would be plotted black in any other case.

i have managed to create an sma that changes colors if it is rising or falling, but i haven't had success in plotting one sma according to how two other sma's are trending. maybe someone with more extensive experience coding in nt could help me.


thanks.

Hello,
Thank you for your post.

You can have the 8 period SMA change colors based off of the two other SMA's by doing something similar to the following:

if(CurrentBar < 1)
    return;
	
mySMA.Set(SMA(8)[0]);
			
if( Rising(SMA(18)) && Rising(SMA(10)) )
{
	PlotColors[0][0] = Color.Orange;	
}
else if( Falling(SMA(18)) && Falling(SMA(10)) )
{
	PlotColors[0][0] = Color.Purple;
}
else 
{
	PlotColors[0][0] = Color.Black;
}

If we can be of any other assistance please let us know.

Cody,


thanks for your super fast reply.


i have tried to paste the code you suggested into a copy of the sma indicator but it won't compile.

i get several error messages, and the one i haven't been able to get past reads something like this:

operator && cannot be applied to operands of type boole and nt.indicator.sma

i see that it will take some time and reading to at least get the basics for coding in nt. is there any kind of manual for beginners that would be recommendable?


thanks.

Codys code was more meant to be its own indicator rather than a change to the original sma. His code already includes everything u need for it to work, ecxept adding the actual plot

here would be his code implemented in a full script. just take ur copied sma file delete everything, paste this code and compile, should work like a charm.

EDIT:you would find this indicator as "coloredSMA" not what ur filename would say. just to prevent confusion.

Hello rtwave,

BigRo is correct here. koganam also refers to the Help Guide documentation that you can find at the following link: http://ninjatrader.com/support/helpG..._resources.htm
