GSB conversion to Ninja trader
Many users are keen to get GSB working on Ninja Trader
The steps will be as follows.
1 get gsbsys1es on your ts going. see this video.
2 compare the oscillators in TS vs NT. GSB/TS has great debug features to do this. GSB can write date, time, osc values, normalized osc values,
result, secondary filter.
3 normalize the data, compare to GSB. This is in GSB_Norm2 function.
4 Build secondary filter
5 add result = osc1*osc2
6 add secondary filter (prev day close)
7 add buy if result >0 and Secondary filter >x
8 then compare trading results.
9 If that works then convert the other oscillators from GSB to ninja
10 Add other data normalization methods in GSB_Norm2
11 Add other entry types. ie cross over of result, two results in a row >x, one result >x
Its the first 8 steps are my main focus. The rest is just tweaking what we have.
NT users contributions to this would be great. I know TS well, but not NT

NinjaTrader Conversion Progress Update
Hi Peter and GSB users,
As discussed with Peter just now, good progress is being made on enabling GSB to output its strategies for NinjaTrader in the same way it is able to
do now for TradeStation and MultiCharts.
The current focus is on compatibility with NinjaTrader8 rather than NinjaTrader7 or earlier versions. This is due to a difference in the underlying
NinjaScript between version 8 and earlier versions.
Initially a sample GSB strategy is being converted from EasyLanguage to NinjaScript and compared to each other for consistency. This will be the
basis of a template for GSB to natively output strategies to NinjaScript. To enable the GSB NinjaScript based strategies to work, a NinjaTrader8
AddOn is being created that contains the custom GSB functions required by GSB strategies. This will make NinjaTrader 'GSB literate'. These functions
have already been created by Peter in EasyLanguage and are being converted to NinjaScript for inclusion in the NinjaTrader AddOn. GSB users will
import the AddOn through the NinjaTrader Control Center.
There remains plenty of work to do, however solid progress has been made. I'll keep the forum updated as substantial progress is made.
Thanks to Peter for your support in this development effort, and for the excellent ongoing work on GSB and its growing functionality.
Cheers,
Jason.

GSB conversion to Ninja trader
Great news on the progress.
I have Ninja Trader and an account with IB so am able to participate in the testing once the templet system is completed.
I am more or less working full time currently with GSB, TS and trading so have the time available.

Progress - Feb 2019
Hi folks,
its been a while between drinks however we've picked up the momentum again on the NinjaScript coding.
Right now we've taken an example strategy, mapped out all its dependent functions, and sub-functions, and their sub-functions (!) and are in the
process of converting and testing those to ensure each function returns the same results in ninja as the do in TradeStation. (see attached)
We've converted the example strategy and so soon we'll put that all together to have a pilot GSB style strategy calling GSB functions, in NinjaTrader.
Pretty exciting.
Once we get that working we'll work our way through the remaining functions then test for consistency between TradeStation and NinjaTrader.
Please note that we are working on coding for NinjaTrader 8 (current release) and have no current plans to re-code for earlier versions.
I'll share more info as we progress through the above development path.

Progress - 1 Mar 2019
More than 100 hours of work has been performed over the past month to convert Tradestation Easy Language scripted functions to Ninjascript functions,
and in such as way as it is easy for GSB users to add them to Ninjatrader and that they work with Ninjascript versions of GSB generated strategies.
And excellent progress has been made.
While based on C#, Ninjascript doesn't always behave the same as C# and deciphering the difference and finding effective ways to work around
Ninjascript's limitations has been frustrating, interesting and very time consuming. Also EL performs in unexpected and undocumented ways at times and
so we've had to be creative in getting Ninjatrader to perform some unnatural acts.
We've tested each function used in the sample strategy mentioned in the prior post in both EL and Ninjascript to ensure they deliver the same output
and so the strategy (and other functions that call them) receive the same input, then treat that input in the same way.
What we've achieved is a working GSB strategy for Ninjatrader 8. See attached screen shot.
Next steps include some further internal testing and alignment of that strategy output on both EL and Ninja. Although we've performed most of work on
this already, we expect some work is still required to align chart times and session templates between TS and Ninja. We expect there to be variations
between how the two platforms handle entries and exits that will have to be worked through.
Once this alignment work is complete we will then crack on with completing the remainder of the functions to support the full range that GSB
strategies might use.
Finally we will finish off the general Ninjascript template to enable all the new GSB features to be captured in strategies that GSB creates.
So encouraging progress so far.
Once we've finished creating all the functions and we're ready for more testing, those of you who are interested will be welcome to submit strategies
that they would like to see working in Ninja. We'll let you know when it's time for that.

Thanks Peter. No that's not GSBsys1ES, its a strategy we took from a GSB run about a month ago, in order to ensure we were using current EL
functions. It was selected for its relative simplicity.
As you can see in the attachment below there are still some alignment issues to iron out as identified in the recent update.

Would be able to do some very basic docs for GBS/NT.
word would do, then i cut and paste into the program that makes the help file.
Thanks for you & Matts work. Its been a big job and a long tome coming.
Its what I enjoy about the GSB community, a lot of people work together to do things that the individual cant do

Yes can do. Will send via email.
See below an example of a random system working in Ninja. Start date is 2006 due to limited historic data from my provider.

Hi I'm excited merchant GSB + Ninja.
I will dedicate the next few days to the test.
I have been a trader for 10 years in automated systems with NinjaTrader, in my champion curriculum with 128% accounts audited in one year, I am
looking for a software that works for me, GSB is among my options, I will be active in the forum.
Greetings to the developers, good working tool, thank you.

Hello,
Integration with Ninja8 when will it stop being beta?
Do you plan to improve the integration and evolution with Ninja8 in the same way as MC or TS?

I think the main issue is new indicators that are released to the beta GSB users, lag in NT. Apart from that I think its fully functional. Currently
there is a regular addition of new indicators most builds.

@remo, need to look via anydesk / teamviewer
I see a few issues
data that starts at 2019 only is totally useless. Its not enough data.
Likely your session time is not configured correctly for MOC to work
I have not worked on dax for years, but I think that 830 to 1500 central USA time with es as data2 830 to 1500
all 30 min bars will work best.
I would not recommend you start on dax. There is much less experience on this market. The next installer of gsb will be great on nq es ym on default
settings

I'm not getting results with the NT data.
I think all the settings are correct.
After Optimize the following exception appears.
Where is the problem? What am I doing wrong?

I have seen that error message when the data file already is in use by another program. Try to close the data file (note pad) and the Ninjatrader
chart with Data Exporter Indicator attached.
