Print only after last Daily bar

[trader3000a]

I have a Print line that does running totals (+=) in OnBarUpdate, so i only want it to Print once. What's the most succinct way to make that happen on Daily bars?

[QuantKey_Bruce]

if (CurrentBars[0] > 0) if (Times[0][0].Date > Times[0][1].Date) Print(Times[0][0].ToString("yyyy-MM-dd") + " : Foo");

Or perhaps you mean:

if (CurrentBars[0] >= 0 && Bars.IsFirstBarOfSession) Print(Times[0][0].ToString("yyyy-MM-dd") + " : Foo");

The former is the date changing. The latter is the session changing.

Hi Bruce,
Thanks for that. I'm cycling through a trade colleciton, and I want to print that line only after the last trade. I'm porting a script from a friend who works in tradestation, and he has something called "LastBarOnChart" that does the trick for him, but I haven't found anything for NT like that.

LastBarInChart would be something crudely like: CurrentBar == Bars.Count - 1 if it's an intrabar strategy, but the best way would be in OnStateChange, in State.Transition, to set a flag that you've reached realtime trading, and then later you can just check that flag.

Hi, If your script is running Calculate.OnBarClose, the last historical bar would be:

if ( CurrentBar == ( BarsArray[0].Count-2))
{
Draw.Dot(this, "LASTBAR", false, 0, High[0], Brushes.Red);
}

If the script is running OnEachTick, it can be written as:

if ( CurrentBar == ( BarsArray[0].Count-1) && IsFirstTickOfBar)
{
Draw.Dot(this, "LASTBAR", false, 0, High[0], Brushes.Red);
}

thanks, Chris!

Hi Chris,
Is there a way to do this when I'm using State == State.Terminated inside of OnStateChange()? for instance:

else if (State == State.Terminated)
{
if (SystemPerformance.AllTrades.Count > 0)
{
foreach (Trade lastTrade in SystemPerformance.AllTrades)
{
lastMfe = lastTrade.MfeCurrency



//adjustMfe += lastMfe / (ATR(14)[0] * Bars.Instrument.MasterInstrument.PointValue); // how do I print this cumulative value only once at the end of the collection?

I would be reluctant personally to do this... do we know that during State.Terminated the SystemPerformance information has not already been broken down? The naming of the state "Terminated" (rather than "PreTerminate" or something like that suggests that the destruction is already underway. Still, maybe it will work if coincidentally that part is disposed later than this part? Have you tried?
