Options Trading Control Web App

I want a lightweight web application dedicated to my options trading workflow. The flow is simple yet strict: once I click “Buy” on a chosen strike, the app must fire a market order with a predefined lot size and instantly attach a stop-loss that guarantees at least a 1:2 risk-to-reward ratio. Quantity and RR ratio should be configurable from a small settings panel so I can fine-tune them before the session opens.

Equally important, the moment I manually close that position—whether by target hit, stop-loss, or a direct “Close Trade” button—the system must impose a “pause” on any further F&O trades for the rest of the trading day. In practice, that means every trading button goes inactive and the interface clearly shows the lockout timer counting down until the next session.

I will supply my broker’s API keys; you wire the trade placement, stop-loss attachment and end-of-day lock logic. Clean, responsive HTML/CSS with a minimal dashboard is all that’s required on the front end; I’m flexible on the back-end stack as long as it runs reliably on a standard cloud host and the code is well-commented.

Deliverables • Integration with the supplied options-trading API (live and paper) • Configurable fields for default lot size and RR ratio • Automatic trading lockout until midnight once a position is closed • Brief README covering setup and any environment variables

I’ll test on my live account once you give me a sandbox build; after we confirm order flow, we go live. Looking forward to a streamlined, disciplined trading tool.
