Session Begin and session End

[blarouche]

Hi guys

I am testing the new version 7. I am migrating from 6.5 and I have met some problems that I would like to address with you this morning.


In my old script I was using ChartControl.SessionBegin and ChartControl.SessionEnd that obviously don't work anymore.


What is the script I should write to get the same result as before.

I tried GetSession()...... like you mention in your email but get compiled errors


Thanks

Hi blarouche,

Please try this:

BarsArray[int barSeries].Session.SessionsOfDay[int dayOfWeek].BeginTime

Here is my old code :

if(ToTime(Time[0]) >= ToTime(ChartControl.SessionEnd)){
...
}

Now I should write :

if(ToTime(Time[0]) >= ToTime(BarsArray[0].Session.SessionsOfDay[3].EndTime));

int barseries being ?
int SessionOfDay : I put 3 but I just need to know if we are in a regular session.


This script didn't work

blarouche,

The concept of Session begin/end times is different in NT7. You now have actual session templates that is controlled in the Session Manager window. Before in 6.5, you only had one session setting which was determined by the chart or whatever you set it as when starting the strategy in the Strategies tab. Now, you choose the session template you want to use for the instrument and it has many start/end times depending on the days.

barSeries refers to which BarsInProgress you are on. If you have a multi series script then you will need to define this as to which instrument you want to be checking. SessionsOfDay[] determines which actually session definition you want to look at. Please open up the Session Manager to get a feel for this. 0 corresponds to the first listed day, 1 the next, etc.

OK I understand.
But my code still don't work.

I get the following error :

The best overload method match for NinjaTrader.Indicator.Indicator.ToTime(System DateTime) has some invalid arguments)
Argument1 : cannot convert from int to System Datetime.

It seems that my code before was returning a DateTime and now with the new script it is returning an int..

Bernard,

That would be correct. Before you were converting the DateTime to an int with ToTime(). Now it is already an int to begin with so you don't need to use ToTime() to further convert it.

Josh

You're right

It now works

Many thanks

Still need help on the following code :


TimeSpan duration = ChartControl.SessionEnd - ChartControl.SessionBegin;


I was looking for a duration TimeSpan between End and Start Time of a session.


What would be the new code ?
I need to return a DataTime object.

Bernard,

These do not return DateTimes. You could try to create your own DateTime by parsing the ints components into hours, minutes, seconds.

You could also try BarsArray[int barSeries].Session.NextBeginTime and .NextEndTime which should return DateTimes.

[blarouche]

Josh

It worked with this :

BarsArray[int barSeries].Session.NextBeginTime and .NextEndTime





Thank you very much

Does it mean if you upgrade to 7 you will have to re-write many of home growth indicator?

nkhoi, for some scripts this is correct - to see code breaking changes, please consult this document which we update as we move forward - http://www.ninjatrader-support2.com/...ad.php?t=21016

SMA of Prior Sessions Daily Range for intraday

Hello Mr Bertrand,

I am hopelesly stuck with trying to code SMA of prior 7 sessions range. Line bellow does not return any value?
double rangeB = PriorDayOHLC().PriorOpen[0]-PriorDayOHLC().PriorLow[0];

I have seen your sugestions on using
Bars.GetSessionBar as well as SampleGetHighLowbyTimeRange, but I am still confused as to implementation of SMA of prior DAILY range?
I know that NinjaTrader 7 supports this better. I really need your sugestions to above or perhaps help to get beta 7.

Thank you.

Gene.

Daily range calculation for intraday chart

Good Morning Bertrand,

You have not reply to my last messages. If you can please look at the code below. I took it from the sample code and tried to adapt it for Open-Low Daily range for intraday chart. It doesn't plot ???

if (EndHour < StartHour)
return;

if (ToTime(EndHour, EndMinute, 0) > ToTime(Time[0]))
return;

if (startDateTime.Date != Time[0].Date)
{
startDateTime = new DateTime(Time[0].Year, Time[0].Month, Time[1].Day, StartHour, StartMinute, 0); //changed to Time[1].Day???
endDateTime = new DateTime(Time[0].Year, Time[0].Month, Time[4].Day, EndHour, EndMinute, 0);//Time[12].Day
}

// Calculate the number of bars ago for the start and end bars of the specified time range
int startBarsAgo = GetBar(startDateTime);
int endBarsAgo = GetBar(endDateTime);



double smaLow = SMA(Low,startBarsAgo - endBarsAgo)[endBarsAgo];
double smaOpen = SMA(Open,startBarsAgo - endBarsAgo)[endBarsAgo];


double Myrange = (smaOpen-smaLow);




double x = Open[0] - Myrange;

MyNumber.Set(x);


Thank you for Help,
