TradingHours -> OrderFlowVWAP

[webus]

Hi,

I want to use the 'OrderFlowVWAP' indicator in my indicator. And I want to add the 'OrderFlowVWAP''s input parameters in my indicator input parameters. However, I do not understand how to create the 'TradingHours' correctly. Please take a look, this is what I want to see in 'OrderFlowVWAP' Indicator:


However, in my Indicator I see just this:


As you can see - this is not a drop down menu. This is looks loke a string value. I cannot choose anything.

Question:
How can I create the TradingHours correctly?

Hello webus,

Thanks for your post.

Please see the forum thread below demonstrating how to create a TradingHours drop-down menu user-defined property.

Hi NinjaTrader_BrandonH,

Hello webus,

Thanks for your post.

Please see the forum thread below demonstrating how to create a TradingHours drop-down menu user-defined property.

Thanks, but please take a look:

protected override void OnStateChange()
{
   if (State == State.SetDefaults)
   {
      tradingHours = TradingHours.Get("CME FX Futures ETH");
   }
}​

As you can see - the trading hours are specified for "CME FX Futures ETH" by default. How can I specify <Use data series settings> instead by default?

Hello webus,

Thanks for your notes.

Setting to TradingHours drop-down input property to "<Use default settings>: would not be possible to accomplish.

To clarify, what exactly will be the use case for adding a TradingHours user-defined property in the script?

For example, if you are trying to create a user-defined input to use for AddDataSeries() calls in the script, this would not be supported. AddDataSeries() arguments must be hardcoded in the method as noted in the help guide.

From the help guide: "Arguments supplied to AddDataSeries() should be hardcoded and NOT dependent on run-time variables which cannot be reliably obtained during State.Configure (e.g., Instrument, Bars, or user input). Attempting to add a data series dynamically is NOT guaranteed and therefore should be avoided."

AddDataSeries(): https://ninjatrader.com/support/help...dataseries.htm

Something you could consider is to leave the default as null, check if the value is null, and then use the BarsArray[0].TradingHours when null.

As I wrote earlier - I want to use the 'OrderFlowVWAP' indicator in my Indicator. And I want to share the 'OrderFlowVWAP' input parameters in my indicator's input paramters. As I can see - in 'OrderFlowVWAP' indicator the TradingHours by default are <Use data series settings>. Please take a look at the screenshot below (you can also start the 'OrderFlowVWAP' on your side) -> so it is possible to specify <Use data series settings>. My question is 'how'?

Hello webus,

Thanks for your notes.

Setting to TradingHours drop-down input property to "<Use default settings>" in a custom NinjaScript would not be possible to accomplish.

You could consider following the advice mentioned in post # 4 in your script. See the forum thread linked in post # 4 for more information.
