Day-trading requires techniques and experience for anyone to be successful and there are people that actually do lose money day-trading even during the bull season.
There's actually more that's losing than winning in day trading. The wins that they have are being shared while the losses, they're kept but they're doing a great job if they're now making their losses into wins.
So even if your other predictions do happen it doesn't stop anyone with the required experience and skills to engage in day-trading.
It's good if your predictions are doing well and being hit, that's just a sign that you've got to do better and you need to be consistent if you're fine as you day trade.
