How it works: Enter your Sunday buy price from Daisy Mae, then the selling prices you've seen each day (AM and PM). The calculator uses the reverse-engineered game algorithm to determine which patterns are still possible and predict remaining prices.

Price patterns in ACNH:

• Fluctuating: Prices alternate between high and decreasing phases throughout the week.
• Large Spike: Prices decrease then spike dramatically (up to 6× buy price) on one day.
• Decreasing: Prices steadily decrease from the buy price all week.
• Small Spike: Prices decrease, then have a moderate spike (up to 2× buy price), then decrease again.
