• ✓Social feed with 50M+ traders sharing analysis — crowd sentiment overlay on any chart
• ✓Real-time data for stocks, forex, crypto, commodities, and indices in one platform

Limitations

• ✓Brokerage+ integration: automatically routes Holly's trade ideas to your TD Ameritrade or Interactive Brokers account
• ✓Simulated trading mode lets you test AI strategies risk-free before live execution
• ✓AI-powered odds calculator shows historical win rate for any pattern on any ticker

Limitations

• ✗Expensive for retail traders — $167/mo is a significant cost against a small account

Limitations

• ✓Backtesting engine: test any K Score-based strategy against 10 years of historical data
• ✓Portfolio optimizer: AI-suggested allocation weights to maximize risk-adjusted returns

Limitations

• ✗K Score is a ranking tool, not a signal — no specific entry/exit price guidance
