EasyLanguage to NinjaScript

[NinjaTrader_PatrickH]

Do you know how to make it save data input via external. I tick the "save data as historical" box, but can I set it in config.xml?

It would be the following in the Config. I recommend testing out changes to the config and seeing hwo they change the document.

    <StoreRealTimeData>
      <boolean>false</boolean>
    </StoreRealTimeData>

no i changed it with notepad,.

Can you supply the changes you made?

[RobinT]

Thanks again.

[RobinT]

all I changed with Notepad was:

<ConnectOnStartup>false</ConnectOnStartup>

to

<ConnectOnStartup>true</ConnectOnStartup>

in

<ConnectOptions xsi:type="ExternalOptions">
<Backup />
<ConnectOnStartup>false</ConnectOnStartup>

[RobinT]

I can see that NT creates a new config.xml to save all its setup options.

is it possible that it is seeing

<ConnectOnStartup>true</ConnectOnStartup>

in

<ConnectOptions xsi:type="ExternalOptions">
<Backup />
<ConnectOnStartup>false</ConnectOnStartup>

as a new interface, as it is creating a new entry in config.xml.

should I be altering something else?

all editing done with notepad.

Hello RobinT,

Thank you for your patience.

You should not need to write to another file and the behavior you are seeing is not expected.

Would you be willing to send the Config.xml that you edited to platformsupport[at]ninjatrader[dot]com with 'ATTN: Patrick H - 1462237' in the subject line?

[RobinT]

I will send before and after.

When you are making a bar with Last () a five minute bar does not print until the first tick of the next bar arrives. Is there anyway you can close a bar or send a dummy value to open the nexxt bar?

Hello RobinT,

There would not be a means to pull the value until the tick to open the next bar is received.

How do I get the DateTime of the lastbaronchart during OnStartUp?

How do I get the DateTime of the lastbaronchart during OnStartUp?

Are you referring to a NinjaScript Object? Such as a Strategy or Indicator?

OnStartUp() would not have the data loaded, so the last bar on the chart would not be accessible.

[RobinT]

Indicator, I feared that, will have to do in OnUpdate. Can you do it there? How?

Also, is there a feedback from Last ? I am flooding the system with data and it seems I am loading it too quickly. If I put a Sleep (50) in after every data point it is ok, but I wondered if there was a buffer full indication?

[NinjaTrader_PatrickH]

Hello RobinT,

You can use Bars.GetTime(Bars.Count-1) for the last bar on the chart.

For the question on Last, are you referring to pulling this in your external application or in NinjaScript? How often are you pulling? When do you need it?

[RobinT]

Bars.GetTime(Bars.Count-1) - Thanks for that,

it is my external application, and I am calling it every 50 ms ok, but if I remove the sleep (50) and pump in data at max speed say 5 data points per ms, it cant take it. Is there a buffer full test?

[NinjaTrader_PatrickH]

Hello RobinT,

There would not be an native functions in the .DLL for buffer or memory management.
