Hi Akros,

We have implemented the Hull MA with our upcoming NT6. Hopefully someone here may be kind enough to convert the KAMA. If we have some time, we will do it for NT6.

Ray

[NinjaTrader_Ray]

How about this?

HMA - Orange
KAMA - Green

Ray

[Akros]

Great! You are working well

Well done!

Anynews for the Quote board?

[NinjaTrader_Ray]

QB will be out with V6 which we anticipate should be out in beta in August.

[ljoe]

Does Ninja have a HMA with color for trend up (Blue) and trend down (Red)?

Thanks

[NinjaTrader_Ray]

By HMA if you mean Hull Moving Average then yes, we support it but without trend based coloring.

[ljoe]

Thanks, what would it take to add the trending color to the indicator? I am not a programmer so if someone could accomplish this it would be great.

[NinjaTrader_Ray]

Maybe someone will be kind enough to help you out. If not, you can contact one of our consultants.

[whitmark]

Here you go ljoe, feel free to modify the colors to suit . . . enjoy!

Regards,

Whitmark

[ljoe]

Thank you very much for the indicator.

[ljoe]

I tried to compile the cs file but keep getting an error "error on generating Indicator." Any suggestion?

Thanks

[whitmark]

ljoe . . . I've pm'd you with my contact info. Please contact me directly and I will be happy to help.

Regards,

Whitmark

[ljoe]

Just wanted to thank Whitmark for all of his assistance and provide me the cs file with the indicator. Finally figured out that one of my templates was causing all the problemd with compiling the indicator. Deleted template and Whitmark's color indicator compiled with out any problem. Indicator is working great, thanks again to Whitmark.

My pleasure, and thanks for posting a follow-up!

[NinjaTrader_Ray]

ljoe,

What do you mean by template? A chart template?
