Locked Percentage Lots

The Locked Percentage feature allows you to fix a lot's value to a specific percentage of the total auction amount. When other lots change, locked lots automatically recalculate to maintain their percentage.

How It Works

When you lock a lot to a percentage (e.g., 25%), that lot will always represent exactly 25% of the total auction value, regardless of changes to other lots.

Example

Imagine you have three lots:

• Lot A: 100 points (unlocked)
• Lot B: 50 points (unlocked)
• Lot C: Locked to 25%

Total of unlocked lots: 150 points Lot C will automatically be: 150 × (25 / (100 - 25)) = 50 points Total auction value: 200 points (Lot C is exactly 25%)

If someone adds 50 points to Lot A:

• Lot A: 150 points (unlocked)
• Lot B: 50 points (unlocked)
• Lot C: Automatically recalculates to 66.67 points (still 25% of total)

How to Lock a Lot

1. Enable "Show Winning Chances" in auction settings if not already enabled

2. Click on the percentage value next to any lot

3. A popover will appear with:

   • Percentage input field
   • Lock/Unlock toggle button
   • Apply button

4. Enter the desired percentage (0-100)

5. Click the lock icon to enable locking

6. Click "Apply" to save

Visual Indicators

Locked lots are visually distinct:

• Yellow/gold percentage text with a lock icon
• Highlighted background with a gold left border
• Tooltip showing the locked percentage when hovering

Multiple Locked Lots

You can lock multiple lots simultaneously. All locked lots will recalculate together when other lots change.

Important Limitation

The total sum of all locked percentages cannot exceed 100%. If you try to lock a lot that would cause the total to reach or exceed 100%, the lock button will be disabled with a tooltip explaining why.

Unlocking a Lot

To unlock a lot:

1. Click on its percentage value
2. Click the lock icon to toggle it off
3. Click "Apply"

Alternatively, manually editing a locked lot's amount will automatically unlock it.

Use Cases

Equal Distribution

Lock multiple lots to the same percentage to ensure equal distribution regardless of bid amounts.

Guaranteed Minimum

Lock a "consolation prize" lot to 10% to ensure it always has value.

Tournament Brackets

Lock winner/runner-up lots to specific percentages (e.g., 60% and 30%) for consistent prize distribution.

Dynamic Prize Pools

As donations come in, locked lots automatically scale with the growing total.

Technical Details

Formula for locked lot calculation:

lockedLot.amount = totalOfUnlockedLots × (lockedPercentage / (100 - totalLockedPercentage))

Automatic recalculation triggers:

• When any unlocked lot amount changes
• When donations/bids are added to unlocked lots
• When lots are deleted or created

Manual edits unlock:

• Manually changing a locked lot's amount unlocks it
• Adding extra amount to a locked lot unlocks it
• This prevents conflicts between manual and automatic values
