Hello esignal, and thank you for your question.

If you want to take action on the last historical bar of the chart, you'll need to record what you need to work with every bar, and take action on the first live bar. That pattern could look like this

[FONT=Courier New]private double saved = 0.0;
private bool processed = false;
protected override void OnBarUpdate()
{
    // updates every historical bar
    if (Historical)
    {
        saved = Close[0];
    }

    // run exactly once with information from the last historical bar
    else if (! processed)
    {
        processed = true;
        Print("CurrentBar" + (CurrentBar - 1));
    }
}[/FONT]

Please let us know if there are any other ways we can help.

hi,
i try it :

protected override void OnBarUpdate()
{
if (Historical)
{
Print(CurrentBar);
}


}

but i see nothing ..

Is correct? ...The "Historical " where i find it in help guide?

My apologies, the example I gave you was for NinjaTrader 7. That documentation is here,

http://ninjatrader.com/support/helpGuides/nt7/historical.htm

To convert this to NinjaTrader 8 we can add the line

[FONT=Courier New]bool Historical = State == State.Historical;[/FONT]

Here is my earlier sample with this addition.

[FONT=Courier New]
private double saved = 0.0;
private bool processed = false;
protected override void OnBarUpdate()
{
    bool Historical = State == State.Historical;

    // updates every historical bar
    if (Historical)
    {
        saved = Close[0];
    }

    // run exactly once with information from the last historical bar
    else if (! processed)
    {
        processed = true;
        Print("CurrentBar" + (CurrentBar - 1));
    }
}[/FONT]

excuse me....i've still the problem
I want to run my loop only one time (it finish historical feed and in that point i want to execute my loop..
How i do can it?

i try

bool Historical = State == State.DataLoaded;
if (Historical)
{
Print("ciao !"); //execute my loop
}

but i don't see it..

Similar if i use State.Terminated or State.Transition or State.DataLoaded...

Can you help me?

I am happy to help. In anticipation of your desire to only run this code exactly once, I included a boolean variable "processed" in my earlier code samples. If you include this in your strategy the way I have, all the code in the "if (! processed)" section will only be run exactly once.

[esignal]

bool Historical = State == State.Historical;
bool processed = false;

if (!Historical && !processed)
{
Print("ciaoff !");
processed = true;
}

it print nothing...
if i don't have connection internet it don't run Print
Other suggestion?

Hello esignal,

Your saved variables must be initialized outside of OnBarUpdate. See,

[FONT=Courier New]private double saved = 0.0;
private bool processed = false;
protected override void OnBarUpdate()
{[/FONT]

i think the problem is that if i don't have connection
it see always Historical..and not real time

i try when i 've connection and it run Ok..
If i don't have it..don't run

Hello esignal,

For situations such as this, where you would like to be in a live state but would also like to backtest a strategy, I highly recommend the playback connection. Here is an instructional video for NinjaTrader 7 on its Market Replay connection. Every concept regarding the NT7 Market Replay connection is valid with the NT8 Playback Connection.
