Arithmetic operations with times.

[Stanfillirenfro]

Hello!

I want to draw Rays based on Time[x].
I want afterwards to be able to move my ray from Time[x] to another. I thought about an integer and I would have something like this:

Time[x] + (y*BarsPeriod.Value)

The problem here is that I am failing to make addition on DateTime and an integer. The best way would be to convert my integer to DateTime or the dateTime to integer, but the number would be very high.
In the dosumentation on DateTime in google, I have seen either comparison or operation on two DateTimes.

Does someone have an idea on how to such operation as specified above?

Many thanks!

Hello Stanfillirenfro,

What are you trying to add or subtract?

Are you trying to add or subtract a number of bars ago?

int fiveBarsAgo = CurrentBar - 5;

// print the time of the bar from 5 bars ago
Print(Time[fiveBarsAgo]);

Are you trying to add or subtract a number of minutes from a date?

DateTime fiveMinutesAgo = Time[0].AddMinutes(-5);

// print the time of the bar from 5 minutes ago
Print(Time[CurrentBar - Bars.GetBar(fiveMinutesAgo)]);

Many thanks NinjaTrader_ChelseaB for your reply.
I am working with 2000 ticks bars and not with time based bars.
I am also in a loop and I want an operation such as:

 for(int i = y; i >= 1; i--)
{
 Time[0] + (i*BarsPeriod.Value)
}

Hello Stanfillirenfro,

What are you using the loop for? What are you trying to loop over?

Ok, you are using tick bars and not time based bars. I understand this. Tick bars are indexed with BarsAgo values and the bar index can still be retrieved by time, just like any other bar type.

What are you trying to add or subtract?

Are you trying to add or subtract a number of bars ago?

Are you trying to add or subtract a number of minutes from a date?

I want to substract the number of bars ago.
I think your explanation gives me an idea. I will implement it in the code and revert to you if I am still having problem.
Thanks again for your help.
