## Named positioning stream — WS `kol.positioning`

The GET /v1/kols/positioning answer (named wallets long vs short per perp, entry, PnL, liquidation risk, 1 h / 24 h flows), pushed on subscribe, then on each roll of the live positions (every 5 s) when it changes.

Layers: HyperCore. Not on Elysium or HyperEVM: positions are HyperCore perps: the KOL stream carries the EVM moves of the named wallets.
