Assigning Data to Custom Series

[DuggyLou]

Ok I want to define a custom series where the end result is a series Velocity[0] = Close[0] - Close[1] and Velocity[1]=Close[1]-Close[2] etc. etc. So far I have coded part of it as following...

public class SeriesTest : Strategy
{
private Series<double> Velocity;
.
.
.

else if (State == State.DataLoaded)
{
Velocity = new Series<double>(this);

I have tried the following code OnBarUpdate

Velocity[0]=Close[0]-Close[1];

But when I print out my Velocity values they are incorrect.

How and where do I correctly assign the Data to my series?

Hello DuggyLou,

If you add print statements which contain the time of the bar, do they differ from what you’d expect?

For example,
Print(Time[0].ToString()+Time[1].ToString()+Close[0].ToString()+":"+Close[1].ToString());

I look forward to your reply.

Here is a sample of my output. I have added the statement you provided and also printed out my resulting Velocity values "Velocity[0] Through Velocity[2].. It looks like Velocity[0] is correct but [1] and [2] are always -0.0399999999999991 and 0.019999999999996 respectively.. How do I get the correct data loaded into the whole series and not just the first value Velocity[0] ?

My code is
Velocity[0]=Close[0]-Close[1];
Print(Time[0].ToString()+Time[1].ToString()+Close[0].ToString()+":"+Close[1].ToString());
Print("Velocity[0] Velocity1[1] Velocity[2]");
Print(Velocity[0]);
Print(Velocity[1]);
Print(Velocity[2]);

I've got it figured out. I've created a Velocity indicator and call that method within my main script. Seems to work fine. Thanks for your input.
