indicator will not plot

October 6th, 2014, 05:33 PM

Hi I'm fairly new to NT and so am not good at it as you may have surmised from the title.

I made an indicator starting with the wizard to plot a dot at the High of Up bars or the Low of Down bars when the percentage of a bars body is <= 49%

I have wasted a few hours trying different things to get it to work.

Attached is a picture of my code and of the Settings.
Please ignore the NumCdls input as that is not being used.

Any help will be greatly appreciated.

Milford.

You aren't testing for CurrentBar > 1 first. If you check the Log, it will tell you as much.

I think you will run into 3 problems:

(1) For the first bar of your chart, which is CurrentBar = 0, you cannot access Close[1] or Open[1], because it does not exist. Therefore, you need insert a line in the beginning of OnBarUpdate()

Code

if(CurrentBar < 1) 
   return;

(2) There are bars that have a zero range when high = low. In that case you will run into a division by zero problem, which you need to exclude.

(3) Rather than using the Plot method to place a dot above or below the current bar, I would use the NinjaScript method DrawDot(), which allows you draw a margin above the high or below the low. If you use the Plot method, you may get unwanted dots, even if you have set no values to the plot.

Thank you so much for this quick reply.
I am now doing the CurrentBar check, making sure I don't divide by zero, and am using DrawDot.
It is now working like champ!

Also discovered where log is! Guess I was pretty much flying blind

Should of come around sooner and saved a few hours

thanks again.
