Working with DateTime

[EastLondonKiwi]

Ok I am working with the DateTime function.

in my example I am capturing the DateTime detail of a specific bar into a variable. myBarTime

private Series<DateTime> myBarTime;

myBarTime[0] = Time[0]

I am then trying to check if the current bar is a specific distance in time from myBar based upon the hour and date values.

if (Time[0].Hour > myBarTime[0].Hour + 5)
{
    Do Something
}

In the above example if myBarTime is a bar that formed at 06:00 the Hour item is 6

I was expecting to be able to add 5 to that and it should return 11

However when I print out the hour value of myBarTime I get 65

clearly the + is not adding the numbers but rather concatenating them.

Can you explain how I achieve my desired result which should have myBarTime.Hour[0] +5 to = 11

Kind regards

Duncan

Hello EastLondonKiwi,

DateTime.AddHours(int hours)
to add minutes use
DateTime.AddMinutes(int minutes)

https://msdn.microsoft.com/en-us/library/system.datetime_methods(v=vs.110).aspx

That said, I am not able to reproduce this behavior.
Attached is a test indicator and a screenshot of how this looks on my end.
Are you seeing that the print is not adding 5 to the .Hour int object on your end.

Thanks Chelsea I think I had a bracket issue that was causing the problem. the time check seems to work now.

however I can not get the Date check to work properly:

Time[0].Date > myBarTime[0].Date

appears to work.

but

Time[0].Date == myBarTime[0].Date

does not?

can you advise

[sledge]

Do some prints to the output window to see what is being compared.

Print ( Time[0].Date.ToString() );

Wouldn't you need in your example : Time[0].Date.CompareTo ( myBarTime[0].Date )

Are you looking for generic code time entry? I picked this up here a long time ago:

if (      ToTime(Time[0]) >= ToTime( 10, 30, 00)
     && ToTime(Time[0]) <= ToTime( 15, 01, 00) )
 {

Print ( ToTime(Time[0]));

 }

You might also be interested in the TimeSpan which has come in handy.

Also you might never see a == condition - trades aren't guaranteed to happen down to any second...

Thanks Sledge, but ToTime(Time[0]) is a value in hour format like 12:00:00 and not a date format.

I found the answer in the function 'Time[0].DayOfYear' which is an int value that is the number of days a bar is from Jan 01 of each year.

That gave me the opportunity to simply test the current bars DayOfYear against the specific bar I was checking how far away I was.

Like this:

Time[0].DayOfYear >= myBarDayOfYear

I think this is the same topic. How can I use the time function to exit or prevent reentry 2 min before session close for example?

[QuantKey_Bruce]

// field variable outside of OnBarUpdate
DateTime MyTime;

// later, in OnBarUpdate
if (SomethingIsTrue) MyTime = Time[0];

// further down, in OnBarUpdate
if ((Time[0] - MyTime).TotalHours >= 5)
{
  // here, it is at least 5 hours after SomethingIsTrue
}

Hello ronaldgreene828,

Thanks for your note.

You could create a time filter to limit trades being placed between a certain time range.

If you want to exit 2 minutes before the session close, you could use a Time condition that checks if the current time is two minutes before the session close time and call your Exit method within that condition.

See this 'How to create time conditions' and 'How to create Time FIlters' sections of the help guide page below.

Thanks. Sometimes it's hard to find that stuff without the correct wording.
