Hi Everyone, My client wants to develop desktop and mobile app for his own purpose (trading of stocks). We need to consult him on best way to build it, so we need someone who has trading experience and can talk his language. Here is the initial description of the project. What we’re building A private pipeline that turns TradingView alerts into IBKR orders with strict risk controls, full logs, and a mobile-first dashboard for monitor/override. You place/modify alerts in TradingView on your phone; the system handles the rest. Architecture (IBKR-specific) A) TradingView (phone or desktop) - Pine Script (indicator/strategy) sends webhook JSON to our API. - We’ll define alert templates (entry, add, reduce, exit; options legs supported via fields). B) Middleware (our server) - Secure webhook endpoint (HMAC). - Risk engine (limits, filters). - IBKR adapter to build contracts and send orders. - Position/P&L tracking, notifications, audit log. - Mobile dashboard (PWA) with 1-tap Pause/Kill Switch. C) IBKR Connectivity (choose 1; I’ll recommend) 1. IB Gateway/TWS API + ib_insync (Python) — Most reliable for multi-leg options (iron condors, verticals) using Combo (BAG) contracts, live market data, bracket orders, and fast updates. 2. Client Portal Web API (REST via Gateway/Docker) — Simple REST, good for single-leg; combo support exists but is less flexible than TWS API.Recommendation: Option 1 for options spreads + robust fills/greeks. D) Data & Infra - Postgres (trades, positions, limits), Redis (queues/locks), Cloud logs/metrics. - AWS/GCP with secrets vault; health checks, uptime alerts.
