Failed to add Volume Delta to my strategy

[FarzadHA]

Hi
I'm trying to build a strategy with strategy builder , in my strategy i wanna use "Volume Delta" indicator to get delta close of candle number one
but when i try to run my script this message popup on script output:
'Volume Delta' tried to load additional data. All data must first be loaded by the hosting NinjaScript in its configure state. Attempted to load 6E 09-23 Globex: 1 Tick
can u tell me what is the problem and how should i handle it please?
(i used calculate on each tick)
thanks

Hello FarzadHA,

Thanks for your post.

This error message indicates that you need to add a 1-Tick additional data series for instrument 6E 09-23 to your strategy so the indicator can properly calculate values. This is because that indicator uses a 1-Tick data series for calculations so the 1-Tick data series must also be added to the strategy.

From the AddDataSeries() help guide: "Should your script be the host for other scripts that are creating indicators and series dependent resources in State.DataLoaded, please make sure that the host is doing the same AddDataSeries() calls as those hosted scripts would. For further reference, please also review the 2nd example below and the 'Adding additional Bars Objects to NinjaScript' section in Multi-Time Frame & Instruments"

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

The Additional Data screen of the Strategy Builder is where you could add the additional data series to the script.

See the 'Understanding the Additional Data screen' section of this help guide page for more information: https://ninjatrader.com/support/help...er_screens.htm
