Code snippet for Parabolic SAR

[FutureTrade]

Dear Support
Regarding the Indicator "Parabolic SAR", can you help me with a code snippet that I can see the dots colored (i.e. up color green, down color red). And how must I implement this code snippet to the right place?
Thanks for advice.
Best
Markus

Hello FutureTrade,

The dots from the ParabolicSAR are a plot.

Plot can be colored on each bar by setting the PlotBrushes for the plot index and bars ago index.

Below is a link to the help guide.

I would recommend doing this in OnBarUpdate after the plot Value[0] is set.

Below is a link to an example script that does something similar. It colors the plot differently for up bars than it does for down bars.

Dear Chelsea

Sorry for late answer and thank you for suggestion. I copied the Standard Parabolic SAR as SARcolored and added following in OnBarUpdate:

if(IsRising(Value))
{
PlotBrushes[0][0] = Brushes.Green;
}
else if (IsFalling(Value))
{
PlotBrushes[0][0] = Brushes.Red;
}

Now I see the dots in Green and Red, but unfortunatelly, the first dot starts with the wrong color i.e. if the trend is long the dots are green but the first dot of this trend is red - but must be in green also - and if the value of a green dot (or red dot) is the same as one bar before, the unchanged dot is "Goldenrod" as defined in AddPlot.

see a picture from the Chart as dpf..

Question: what made I wrong?

Thank you and best regards
Markus

Hello Markus,

Thanks for your reply.

This is Paul responding for Chelsea who is out of the office today.

The first dot is not being colored because the methods IsRising() and IsFalling() require two data points to determine the rise and fall status. The dots are colored the original color because they are neither rising nor falling so you have no condition to color them.

If I may suggest, please comment out your code and try this: PlotBrushes[0][0] = Value[0] > Close[0] ? Brushes.Green : Brushes.Red; as i think that will get you what you are looking for.
For clarity: Value[0] > Close[0] ? Brushes.Green : Brushes.Red is read as: If the current Psar value is greater than the current close price, color the brush green, otherwise color the brush red.

Dear Paul

Wow - so easy with your suggestion. Now it works very fine. I have to learn a lot more in programming...

Thank you so much for this and I wish you a very nice weekend.

Hello Markus,

Thanks for your reply.

I have to correct something, "The first dot is not being colored because the methods IsRising() and IsFalling() require two data points to determine the rise and fall status. The dots are colored the original color because they are neither rising nor falling so you have no condition to color them." That was incorrect, they were not colored the original color, rather they were colored according to the previous direction. Sorry if that added any confusion.

Glad the example worked for you.
