About Pretrend
Pretrend is a trend-based oracle protocol for prediction markets. Instead of a yes-or-no outcome, every market resolves on the magnitude and direction of change, measured by an ordinary least squares regression computed natively on the Vitruveo blockchain.
What it does
A Pretrend market asks how much something will move, not whether it will. Prices from a live feed are sampled over a fixed window, a trend line is fit across the whole window, and the slope lands in one of five graded outcome buckets. The computation runs inside the chain through the Trend precompile, so settlement is deterministic and verifiable by anyone.
Who builds it
Pretrend is developed by Vertical Foundation as part of the Vitruveo ecosystem. The statistical engine ships inside the Vitruveo protocol itself; TrendPulse, the oracle, publishes the feeds; and AIWars Trends is the first game built on top of them.

The math behind the trend. How ordinary least squares turns a window of noisy prices into one defensible slope, and why that slope is hard to manipulate.
