So recently I've been dip buying premarket spikers that IRIS likes or judges to be good stocks, but the places where I need to dip buy have been kind of nebulous for me. Tim likes buying near VWAP, so I'm thinking about doing that instead, it worked on two separate stocks this morning with amazing spikes afterwards. I woke up late because the stupid alarm on my phone didn't work, but now I can see what happened here with a somewhat more clear head. However, I don't think this is always applicable (like if the VWAP is wayyyy above where the stock price is at.) But you can just wait for the stock to trade sideways and get a volume spike + a solid green candle.
