Has anyone else had this issue?

Hello WilyCa,

Thank you for writing in.

Did you replace your existing @EMA file when you were prompted when you imported?

I look forward to your reply.

[WilyCa]

Hi Zach,

No, I didnt. It looked a fairly terminal error. Could you explain in idiot proof steps how I woudl go about this?

[NinjaTrader_RyanL]

Hello WIlyCa,


Thank you for the follow up.


To import indicators you will need the original .zip file.

Here is a basic guideline of how to Import indicators.

To Import
1. Download the indicator to your desktop, keep them in the compressed .zip file.
2. From the Control Center window select the menu File > Utilities > Import NinjaScript
3. Select the downloaded .zip file
4. NinjaTrader will then confirm if the import has been successful.

Critical - Specifically for some indicators, it will prompt that you are running newer versions of @SMA, @EMA, etc. and ask if you want to replace, press 'No'

Hello and thanks for your post.

If you change the setting of CalculateOnbarClose from true to false, the bar being formed will change.

Please let me know if I can be of further assistance.

[shinmycock]

Thanks

Works! Thanks Paul.

Time Frame

Dear All,
The signal that can generate this trading system could be interesting to look at: It gives the trend from different time frame.
However, personaly, a minor time frame chart should be consider as a "tactical chart" for entries.
Q: How I can get this famous signal on a minor time frame chart with this Zip file ?

Sorry I am new or Jumior with NT...
Thanks in advance.
----------------------------------------------------------------------------------------------------------------------------

Dear all,
Greetings !
Quick question: how to you get THE signal on this strategy ?
It is a multiple time frame strategy so do you need to open at least 2 charts and run on both this strategy to get THE signal on the inferior time frame ?
Thank you in advance for your kind help.

I couldn't get the indicator to work, but as I was only slightly curious, I havent pursued. The webinar below explains the indicator. Not sure of your level of knowledge, but the indicator is not a stand alone entry/exit tool.

Thx wilyCa

Hello,

I just downloaded the Elder Impulse System.. Is there any kind of documentation on how this strategy works..?

Thanks Michael

Hello,

I figured out how to use Google 20 years ago..

All I need is a bit of clarification.. Let me rephrase my last post... How do you work the strategy based on it's properties..? Please...

Thank You..

Michael

Hello Michael,

Thanks for your reply.

In the NT7 strategy (which the NT8 version was converted from) the description provides two links for the strategy. I do not know why the description was not copied to the NT8 version.
For your convenience here is the NT7 description with links:

Elder Impulse trading system. Includes support for a second, higher time frame period for determining trend and momentum. The background is painted pink when the higher time frame trend and momentum is down, and green when it is up. The rules for entering and exiting a trade are described here on Investopedia and Stockcharts.com.

Please note that the NT7 strategy was provided by member shodson to begin with.

[Mykro]

Paul,

I'm confused on how the parameters work in it's properties window.. HTFType, HTFPeriod, TradeTimeBegin, TradeTimeStart.
I understand the concept of the strategy..
