Bid Increment Table

The BidIncrementTable defines how much the next valid bid must increase based on the current bid amount. It ensures that bids follow a clear, predictable progression as auction prices rise.

🔢 Example Table

Low Range	High Range	Step
0	100000	2500
100000	5000000	10000

💵 All values are in minor currency units (e.g. cents for USD).
For example, 100000 = $1,000.

💬 Human-Friendly Interpretation (USD)

With the table above, here's how to read it:

From $0 to $1,000 → bids increase by $25

From $1,000 to $50,000 → bids increase by $100

If the bid exceeds the highest HighRange (in this case $50,000), the increment remains fixed at the last step: $100

✅ Validation Rules

To be valid, a BidIncrementTable must meet these requirements:

Each range must align

LowRange and HighRange must be divisible by Step
Step must fit evenly within the range (HighRange - LowRange)

Rules must be continuous

The first rule must start at 0
Each rule’s LowRange must equal the previous rule’s HighRange

At least one rule is required

🧠 Summary

Controls how bid amounts increase over time

Dynamic and price-dependent

Keeps auction pacing smooth and scalable
