I am looking for an expert developer to build a highly advanced mobile cryptocurrency trading application for iOS and Android. The app must operate with maximum accuracy, integrate with multiple exchanges (MEXC, Binance, and others), and allow trading on one platform or multiple platforms simultaneously based on my selection. The app must support all trading pairs and all order types available on the exchanges, including Market, Limit, Maker, Spot, and more. Maker orders must never auto-convert into Market under any circumstances. The system must support all timeframes, from seconds up to yearly. ⸻ Core Features Required 1. Multi-Exchange Integration • Full integration with MEXC, Binance, and other platforms. • Ability to trade on one or multiple exchanges at the same time. 2. Full Trading Functionality • Support for all trading pairs. • Support for all order types. • Strict enforcement of Maker/Limit rules. • Support for compounding and capital-splitting strategies (e.g., $1000 divided across 24 candles). 3. Candlestick Strategy Engine • Entry conditions based on: • Current candle (open/close/high/low/midpoint/% offsets) • Previous candle (open/close/high/low/midpoint/% offsets) • Stop-loss and take-profit using the same reference options. 4. Technical Indicators Strategy • Full access to all platform indicators. • Ability to add and use paid indicators. 5. Order Book Strategy • Buy/Sell based on: • Specific row (row 1, row 2, etc.) • Percentage of row quantity • Order-book-based stop-loss and take-profit. 6. Multiple Buy Executions If a partial buy is filled and the price returns to entry without hitting take-profit within the same timeframe, the system must auto-execute the remaining amount. If take-profit is hit first, no additional buys occur. 7. Multi-Strategy Operation • All strategies must run simultaneously. • Each strategy can run on multiple coins. ⸻ Precision & Performance • High precision numerical settings (not less than 2 digits). • Must operate 24/7 with high efficiency. ⸻ Support & Ownership • Continuous technical support with no delays. • Small future modifications must be free. • Full source code and full IP ownership. • App must never be published or sold. ⸻ Delivery Requirements 1. Must be connected to the external receiver (monthly subscription provided by me). 2. Must match the quality and performance of Binance’s official mobile app (native-level development). 3. Must include every requirement exactly as written — no changes, no removals. 4. Delivery time: 1 month. 5. Result must be top quality, extremely accurate, and delivered on the agreed date. ⸻ Important Financial Notes • Budget: $3000 (non-negotiable). • Payment: One full payment after final delivery and full testing. • No milestone releases, no partial payments. ⸻ Acceptance Conditions (Mandatory for Developer) 1. You fully accept every point in my requirement document exactly as written. 2. You fully accept everything discussed in the chat. 3. The app is for my personal use: no login/register system and no multi-user setup. 4. Zero compromises — any missing feature must be corrected before payment. 5. I have the full right to request a full refund if: • Delivery is late, or • The app does not match the specs exactly. ⸻ Final Testing Procedure • You will run the app for 2 days using the 30-minute timeframe with 3 strategies running simultaneously on several coins. • After confirming stability and correctness, I will test it on my side using a secret API key. • Only after full verification will payment be released.

Hello, I can help you build a native-quality crypto trading app for iOS and Android that connects to Binance, MEXC and other exchanges, executing every order type (Spot, Limit, Maker, etc.) with strict control so Maker orders never slip into Market. I’ve worked on multi-exchange trading tools, strategy engines and order-book–driven logic, so I can implement your candle/indicator/order-book strategies, compounding, multi-strategy/multi-coin operation and 24/7 reliability exactly as specified. The app will run with a single user (no auth system), integrate with your external signal receiver, and expose precise, high-granularity numeric settings so you can fine-tune behaviour per pair and timeframe. I’ll deliver clean, well-structured code with full source and IP handed over, plus ongoing technical support and small adjustments after delivery to keep everything running smoothly. If you’d like, I can first review your full requirement document and propose a day-by-day implementation plan to comfortably fit your one-month deadline. Best regards, Juan
