📈 Price Candles + Volume

Candlestick — each candle is one month. Open=last month's median sale, Close=this month's median sale. Wick extends to the median list price (proxy for the high/low range). Green = month-over-month gain, red = decline. Bars below = homes sold (volume).

💰 PPSF (Price-Per-Square-Foot) + DOM (Days On Market)

PPSF normalizes price across different home sizes — a 2,000 sqft house at $1.5M ≠ a 1,000 sqft condo at $1.5M. PPSF lets you compare like-for-like.
DOM = median days a listed home stays on market before going pending. Low DOM (under 14 days) = hot market; high DOM (40+) = inventory piling up, buyers have leverage.

📦 Inventory & New Listings

Inventory = active listings at month-end. New listings = brand-new this month. Rising inventory + flat sales = market cooling.
