Price Scale (0 to 100 vs 0 to 1)
Price scale is the numeric convention used to display prices and probabilities, commonly 0 to 100 or 0 to 1.
Definition
Price scale is the convention used by a platform to display contract prices. Two common scales are 0 to 100 and 0 to 1. They represent the same information, just in different units.
How to convert
• 0 to 100 to decimal: divide by 100.
• 0 to 1 to percent: multiply by 100.
Why it matters
Most mistakes in probability tools come from mixing scales. Scale confusion breaks comparisons between predicted probability, fair price, and implied probability.
Common pitfalls
Entering 0.55 as 55: That is a 100x error.
