I build trading bots, custom indicators, automation systems, and signal-to-execution bridges for traders, funded-account users, and fintech teams who want tools that actually work in the real world.

My main playgrounds: NinjaTrader 8 TradingView Pine Script MetaTrader 5 / MQL5 Sierra Chart cTrader What I can help you build, fix, or upgrade: - NinjaTrader 8 strategies, indicators, add-ons, and bot fixes - TradingView Pine Script indicators, alerts, and strategy automation - MT5 Expert Advisors, trade managers, and MQL5 debugging - Sierra Chart ACSIL studies and platform integrations - Discord, Telegram, webhook, and API-to-platform trade bridges - Risk tools like trailing stops, breakeven, drawdown limits, session filters, position sizing, and more - Strategy conversions between NinjaTrader, MT5, TradingView, cTrader, and Sierra Chart - Python/C# integrations, data pipelines, dashboards, and machine-learning filters Got an idea sitting in your head?

🏛️ 𝐀𝐥𝐩𝐡𝐚 𝐝𝐢𝐞𝐬 𝐢𝐧 𝐛𝐚𝐝 𝐢𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞. Brilliant quantitative logic is worthless if your execution architecture bleeds capital under live-market pressure. I see it constantly: founders deploying systems that print money in backtests, only to watch them collapse in production because their MT5 terminals or TradingView webhooks aren't properly bridged to a high-performance backend. I solve this. As a Quantitative Systems Architect, I build sub-millisecond Python execution vessels that turn fragile, isolated trading scripts into resilient, production-ready infrastructure. With deep experience in financial market infrastructure, I specialize in Project Rescue and Scale-Up Architecture. I act as your hands-on Technical Partner: one single point of contact, strict engineering rigor, and absolute risk control. ━━━ 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 ━━━ Algorithmic Trading & Execution Engines Architecting institutional-grade automated systems natively across MT5 (MQL5) and TradingView (Pine Script v6). Building sub-millisecond Python execution vessels, utilizing WebSockets and ZeroMQ to route signals instantly from your Master API to the broker. Trade lifecycle management: precise order chunking, slippage caps, and dynamic trailing logic. Fintech SaaS & Prop Firm Infrastructure Designing high-concurrency B2B dashboards and server-side risk management microservices (Next.js, FastAPI, MetaApi). Enforcing strict Prop Firm drawdowns, daily loss locks, and automated equity syncing to protect capital from emotional trading. Bridging traditional frontend terminals (MT5/TV) with robust Python backends. Broker API & Data Pipelines Direct integration with Rithmic (R-API+), Binance, Bybit, and FIX protocols. Structuring historical MBO, tick-level, and order-book data ingestion pipelines (e.g., Databento) for accurate backtesting and ML-feature extraction. ━━━ 𝗪𝗛𝗬 𝗙𝗢𝗨𝗡𝗗𝗘𝗥𝗦 & 𝗤𝗨𝗔𝗡𝗧𝗦 𝗪𝗢𝗥𝗞 𝗪𝗜𝗧𝗛 𝗠𝗘 ━━━ I Understand Both Software Engineering and Quantitative Finance I speak your language. I don't just understand basic SL/TP; I understand Level 3 Order Books, Liquidity Voids, Lock-free Ring Buffers, and Structural Risk Validation. I don’t approximate your logic; I implement your mathematical models exactly as defined. Exact Logic, No Guesswork I build systems from the ground up with strict determinism. Every rule is coded, logged, and tested. If a condition is ambiguous, I clarify it before execution to ensure the system behaves 100% as expected under live-market stress. Zero Hand-Holding Required As your Fractional CTO, I don't just write code blindly. I audit your architecture, tell you exactly what is causing latency or system failures, and execute the fix. ━━━ 𝗧𝗘𝗖𝗛 𝗦𝗧𝗔𝗖𝗞 & 𝗣𝗟𝗔𝗧𝗙𝗢𝗥𝗠𝗦 ━━━ Languages: Python, C++, MQL5, Pine Script, TypeScript. Trading Platforms: MetaTrader 5 (MT5), TradingView. APIs & Data: Rithmic (R-API+), MetaApi, Databento, REST/WebSockets, FIX Protocol. Backend & SaaS: FastAPI, Next.js, ZeroMQ, Docker, Microservices Architecture. 🚀 Let's build something that scales. Send me your trading strategy, MT5 setup, or SaaS architecture plan. I will tell you exactly where the bottlenecks are and outline a strategic roadmap to fix them. ━━━ Keywords: Fractional CTO | Quantitative Finance Architect | Enterprise SaaS Architecture | Algorithmic Trading Systems | MT4 | MT5 | MQL5 | NinjaTrader 8 | NT8 | C# | TradingView | Pine Script | Prop Firm Tech Stack | Binance API | CCXT | Crypto Exchange Integration | Blockchain Developer | Web3 Infrastructure | DeFi Protocol | Payment Gateway Integration | Node.js | Next.js | Python | High-Concurrency Backend | Microservices | MetaApi | PCI-DSS | Project Rescue | High-Agency Developer

At A Glance: MQL 4

MQL 4 is a programming language used to create scripts as well as custom indicators, expert advisors, and even libraries. It is not a beginner’s programming language, and for that reason, when a business needs work on a project of the nature the language covers, they hire MQL 4 professionals and consultants on Upwork. But what would a business need these experts to write for them?

Scripts are one of the major areas the language is used for, and these are the everyday commands submitted to computers in order to perform different operations. These can be general commands as well as specific ones such as analyzing charts or generating statistical information. Then there are custom indicators that are used to make create charts or other visuals. These operate at a much more complex level, with every tick on a chart or every function needing its own custom indicator. Expert advisors are used in financial programs and most often in financial market trading software. Finally, libraries in computer terms are sets of functions that perform specific tasks. In a financial business, this could be used to decide when to sell and when to buy.

What this all means is that working within the MQL 4 language isn’t something that can be done by just anyone without expert knowledge. Training and experience are required to be able to use the different features of the MQL 4 language and ensure that what’s created with it is functional and fit for its purpose.
