Dollar Cost Averaging is a similar approach to the strategy you propose today. Take your total investment strategy and spread it over a timeline to mitigate the volatility risk, this way you don't go all-in on a spike, but spread over time.
For example, 6-8 weeks with a weekly buy in. $8,000 investment purse purchased weekly at $1,000 per week will spread your risk across the volatility. You can accelerate the buy-in during down trends to take a small benefit from the market movement.
