According to research, the odds of two sisters having twins are approximately 1 in 80 pregnancies. This is if both pregnancies were conceived naturally without any medical intervention. The odds of two sisters being pregnant at the same time with twins are around 1 in 6,000 - 7,000 pregnancies.

If your sister had identical twins then you have the same odds as anyone else as it is a fluke and not determined by genes etc. However if your sister had fraternal twins your chances are significantly higher than those who do not as this is considered to be passed down.

I think this is a case just like flipping a coin... the odds of one toss are not affected by the preceding or following coin tosses. Each pregnancy has a slight chance of resulting in twins, and the chances are low (unless you are using some fertility techniques)

Your odds of having twins do not increase, nor do they decrease if your relative (sister) gives birth to twins.
