Comprehensive Stock Option & Equity Monitor

I'm looking for a software solution that can monitor my stock options, equities and index futures transactions. The software should also draw a gain/loss curve related to these transactions, and automatically execute buy/sell orders with my Robinhood brokerage account.

Key features:
- Monitor stock options, equities, and index futures
- Visualize gains and losses using line charts, bar graphs, and pie charts
- Automatic execution of buy/sell orders with Robinhood

Ideal candidates for this project should have:
- Experience in developing trading software
- Familiarity with Robinhood's API for brokerage account integration
- Skills in data visualization and creating user-friendly interfaces
