Market buy vs Limit Buy

I understand the difference between market and limit buys/sells. I always use limit, but the other day I held off buying AMZN until their earnings came out. When it did, after hours, the price movement was changing so fast It was difficult to keep up to but a limit buy in. Probably a stupid question, but what’s the best strategy to place a limit buy when the price is moving so fast? Thanks.

Edit: appreciate all the responses. To clarify, after hours fidelity doesn’t allow market buys. And I purely day trade and swing trade so at times I do chase, though I know I shouldn’t.
