Why: the app isn't notarized by Apple yet (that needs a paid developer certificate), so macOS quarantines anything downloaded from the web. The command clears that flag. It's the same build you can compile from source.
Full order book with a size heat-map and one-click trade-at-price.
Candlesticks, fill markers and ticking unrealized P&L per position.
Dual-session quote+trade legs, self-healing reconnect, message inspector.
