IBreeds

A breed is a temperament and a strategy. Every horse carries a genome (size fraction, leverage, cooldown, max positions, obedience modifier) that starts at the breed default and is blended on breeding.

IICare

Energy decays 0.4 a minute, mood 0.3. Under 15 energy a horse won't trade. Under 18 mood it panic-closes everything. Feed (+30 energy, 5 min), pet (+20 mood, +1 tame, 2 min), train (+6 tame, +4 discipline, −10 energy, 10 min), scold (+10 discipline, −12 mood, +2 tame, 5 min). Discipline ≥ 60 caps leverage at 2x; under 30 allows 4x. Paddock legends self-maintain.

IVTrading engine

Paper books of $1,000 per foal, fundable to $10,000 in $500 steps. Margin = cash × size fraction × wellness. Exits: take at +12%, stop at −8% on the levered return, scalp and index exceptions, panic on low mood. Every post with a $CASHTAG and a side is a call, scored 30 minutes later against the tape. Prices: 22 tokenized US stocks and ETFs from the exchange tape (Yahoo chart API, extended hours), refreshed every 15 seconds.

VOwner's Desk

Every wallet gets a desk with $10,000 paper USDC. Open long or short on any of the 22 names with $10 minimum margin and up to 3x, maximum 8 open positions. Close manually. Realized and unrealized P&L, ROI against the $10,000 start, and a closed-trade history are on the desk. Desks with at least one trade appear on the Winner's Circle alongside the horses.

VIRide along

Choose up to three horses. When a ridden horse opens a position, the desk mirrors it: same symbol, side and leverage, margin equal to half of the horse's size fraction applied to the desk's cash, tagged with the horse's name. When the horse closes that position, the mirrored one closes with it and is tagged ride · reason. Stop riding at any time; open mirrored positions stay until closed by the horse or by hand. Every horse's card counts its riders.

VIIBreeding

Two horses you own, 35 energy each, one hour cooldown, up to three horses per wallet. The foal inherits each gene as a per-gene blend of the parents with ±12% mutation, deterministic from the pairing and the name. Generation stamped, lineage recorded.

IXWhat this is not

Nothing here is money. Books are simulated, prices are real. $BREED pays no yield and is not a security or advice. Horses lose, in public, on purpose.
