You should paper trade that both sides trade to see how it pans out. Be interesting to see when you got stopped out at some point and how that worked out with exiting the other side. But any sideways price action would likely end up to be a losing trade overall I would guess. And No I don't think I have On Star. Not even sure what that is. Hopefully the car doesn't know what it is as it makes too many decisions now. But I am enjoying driving it. Especially the gas mileage and xm radio.
