am looking for an experienced developer to build a lightweight, fast, user-friendly desktop application for my intraday manual trading on Indian markets (NSE equities & futures). Core Requirements: Super-fast stock selection Quick search bar / hotkey-based selection of any equity or futures contract. Ability to load watchlists or F&O scrips instantly. Goal: I should be able to pick any stock in 2–3 seconds while the market is moving. Manual trading with smart predefined risk management One-click Buy / Sell. Predefined (but fully editable) Target, Stop Loss, and Trailing Stop Loss values (in price or %). I must be able to change Target / SL / Trailing values on the fly even after the position is taken. Once order is placed, the system automatically monitors and manages Target, SL, and Trailing SL in real time. Order type logic (very important): Equities (Intraday) → Always use Market Order for both Buy and Sell. Futures → Use Limit Order with user-defined buffer % on both sides (I will set the %). This is to handle liquidity issues. The system should calculate and place the limit price automatically with the buffer. Broker Integration: First priority: Full integration with Zerodha Kite Connect API (REST + WebSocket for live data). The architecture must be modular so that later I can easily add support for other Indian brokers (Upstox, Alice Blue, Angel One, etc.). Login flow, order placement, position tracking, order modification/cancellation, P&L, etc. must be handled cleanly. Real-time features needed: Live price feed (WebSocket preferred). Automatic monitoring and execution of Target / SL / Trailing SL (since Zerodha no longer offers native bracket orders, this logic must be built in the app). Position monitoring, auto square-off option, trade log.
