Trend Bar Painting

[zhawenx]

First of all, a big THANK YOU to Chelsea at Ninjatrader for all the links provided to get this started.

This is my 1st Ninja script here and I need some help. I used script from ColoredScalpBar8 and replaced its indicator logic with current one.

The idea is simple. I want to paint the bars with the same color as long as they stay in the same trend. The trend is defined as below:

double close0 = Close[0];
double SMA1 = SMA(Close, 6)[1];
double ATR1 = ATR(6)[1];

if (close0 > (SMA1 - atrPercent*ATR1))
{BarBrush = UpBrush;}
else
{BarBrush = DownBrush;}

But it did not compile well and I attached screenshot here. I could not figure out why "UpBrush" and "DownBrush" were declared fine in ColoredScalpBar8 but not in my script.

Would really appreciate some help. Since there are compiling errors, I don't know how to export the script. Hence the screenshot only.

Hello zhawenx,

Thank you for your post.

I can't see in the screenshot provided where you've initialized any of these variables. Could you copy and paste the entirety of the code you currently have into your reply?

Thanks in advance;I look forward to assisting you further.

Hello zhawenx,

Thank you for your reply.

The code provided is not the code shown in your screenshot. Can you just select all the code in that window and copy it, then paste it into your reply?

However, from what I am seeing you are not initializing your variables before you try to use them. Do you have something like this in your code before OnStateChange()?

public class wzTrend : Indicator
{
//initialize the variables we will be using
private Brush UpBrush;
private Brush DownBrush;
private double atrPercent;

protected override void OnStateChange()
{
//code continues

Thanks in advance; I look forward to assisting you further.

Thanks Kate. That's exactly where the problem was. eDanny has pointed this out and is helping me with another issue. Will post the script once it's done.
