NT8 Questions

[RiversideDude]

1. If I modify a strategy that's running, how do I get the new changes to take affect?

2. Can I change a user defined input value while the strategy is running?

3. I only trade currencies. Can I hide the other markets?

4. Can a strategy manage a manually created position?

5. Can I create a dashboard? Can a strategy process data from more than one pair?

Hello RiversideDude,

Thanks for writing in.

As allowing the changing of user defined inputs on-the-fly could cause for a lot of unexpected behavior, this feature is not allowed. Strategy parameters must be modified by disabling and re-enabling the strategy.

You can create instrument lists to conveniently monitor any group of futures, FOREX, or stocks. You can learn more about using instrument lists in NinjaTrader 8 here: http://ninjatrader.com/support/helpG...ment_lists.htm

There are two different approaches to creating strategies in NinjaTrader 7 and NinjaTrader 8 referred to as the Managed Approach and the Unmanaged Approach. The Managed Approach will allow you to create strategies without having to control orders exactly for each profit target and stop loss. The Unmanged Approach allows you to manage raw orders and you can manage the orders based on your current market position. The Unmanaged Approach is intended for experienced developers who want complete control of their strategies. You can learn moire about creating strategies with the documentation below:

Yes you can create a dashboard. A watch list can be made in the Market Analyzer with customizeable columns and alerts, or you can create your own window to manage and watch your instruments.

Market Analyzer documentation: http://ninjatrader.com/support/helpG...t_analyzer.htm

You may want to looking into creating your own window if the Market Analyzer does not fulfill your needs.

Strategies can access more than one pair by adding additional data series to that strategy. We have this documented in our help guide here: https://ninjatrader.com/support/help...dataseries.htm

DaystoLoad & BarstoLoad

In my strategy I am using the Pivot indicator. It requires maybe a month or 2 of historical data. when I enter a large number for DaystoLoad say 60 days the pivots calculate fine. Now In the strategy analyzer I only want to test one day at a time to see the results. So I Put same day for the start and end date. Instead of giving me one day it give me historical data when I run the strategy analyzer. Is there a way in the Strategy Analyzer to only get results for one day but still calculate the pivots correctly in my strategy.

Hello dlespinasse50,

Thanks for writing in.

To answer your question directly, no there is not any specific setting in the Strategy Analyzer to have a back-tested strategy use different data series per indicator. This must be coded manually.

To restrict historical trades from showing up in your back-test, you may want to add a return condition for historical data in OnBarUpdate():

protected override void OnBarUpdate()
{
  // only process real-time OnBarUpdate events
  if (State == State.Historical)
    return;
    
  //rest of logic           
}

To have your pivots form off of historical data that you are not inputting to the Strategy Analyzer's primary data series, you will want to add an additional data series to your strategy that will be used for pivot calculations.

We have a reference sample on creating an additional data series for calculating values outside of the primary data series. I will provide a link below:

http://ninjatrader.com/support/forum/showthread.php?t=6652

Please also take the time to read the documentation for the components listed within as well as the documentation on creating NinjaScript for Multi-Time Frame & Instruments:

http://ninjatrader.com/support/helpGuides/nt8/en-us/multi-time_frame__instruments.htm

Syntax for using Pivots in NinjaScript can be referenced here: https://ninjatrader.com/support/help...us/?pivots.htm

If you have any further questions, please don't hesitate to ask.

Thank you very much for your answer. My program is getting a compile error when I use the
if(Historical)
return:

It says its not finding Historical in the context. Do I need to define it some where and check for a condition?

[NinjaTrader_Jim]

Hello dlespinasse50,

Thanks for writing back.

Yes, you are correct. if(Historical) does return a compiler error in NinjaTrader 8. NinjaTrader 8 uses a State system now which allows for other states other than Historical and Realtime. You can read about the State system here: https://ninjatrader.com/support/help...n-us/state.htm

You will be looking to add the following code to your strategy instead:

protected override void OnBarUpdate()
{
  // only process real-time OnBarUpdate events
  if (State == State.Historical)
    return;
    
  //rest of logic           
}

I will update my last post to reflect this correction.

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

Thanks again for your response. I drop that code in there and there was no errors but My did not have any orders. Nothing is getting pass
State == State.Historical
Return;.
I tried to use the link that you provided to read up but It says I am not authorize.
