Doesn't sound like you were really expecting this. So if you weren't and didn't have a set plan to breed Oscars I'd say let the parents watch the babies. Oscars make great parents (usually) it will be fun to watch them care for the young.
What else is in the tank?
The next day I woke up and there was no sign of the babies anywhere. I have a Sveni Pike in there but theres no chance the parents would let him get near. I think the parents ate all the babies at night.

Most cichlids(including oscars) will hide wrigglers, so not seeing the wrigglers until they become free swimming is quite common.
But pike cichlids are very efficient fry predators, and can easily and quickly swoop in grab a mouthful of wrigglers, and then just as quickly retreat.
They are also very good at picking off free swimming fry.
If you want to keep fry, the pike cichlid should be in another tank, as should any other wriggler, fry predators like Pleco's or tetras.
One of the reasons oscars and other cichlids eat their own young, is if they figure the odds are against them to be raised successfully.

I agree pikes are incredible predators. Even if the Sveni didn't eat the fry having a pike with them is stressful when they have fry. The other option is to siphon out the fry. They will most likely spawn again though.
