Doubts about how to maintain (roll) a future positon?

At first I guess rolling a future potion by volume should be reasonable. But I did a simple research shows maybe simply roll by volume maybe too early. VXQ17 expires around 8/17/2017. Using volume to roll cause the rolling happens at 2017-08-08, there's 8 days remaining,the front one is still active traded. The other way roll by calendar date maybe too late.
My intention is to maintain a short current VX future position. Is is possible to define a way to roll (roll after the second future's volume> first future's volume*1.1)? I need some suggestion,plz

I guess use continuous_future('VX')? I am also new in quantopian.

Hi,

I would recommend you checking out this community thread where Jamie shared an example of how to customize the way your algorithm rolls your portfolio positions.

For clarification, the roll attribute of a continuous future specifies how to determine the primary contract on that future's chain of active contracts. It does not deal with rolling or moving positions from one contract to the next.

I hope this helps.
