    Coming from the cybersecurity world, where I developed rigor, automation, and system reliability, I have progressively transferred these skills to advanced trading.

    I worked on prop-firm trading (crypto & indices), successfully passed several challenges, and obtained a validated payout of €5,000, applying a structured, data-oriented methodology.

    My approach is based on the same principles as cybersecurity: analysis, risk management, monitoring, stability, automation, and code quality. I also design PineScript indicators and automated trading bots (Python / APIs) to systematize my strategies.

    APPROACH & METHODOLOGY (Cyber → Trading)
    • Structural analysis: liquidity, key zones, volatility
    • Real-time data: CVD, OI, funding, liquidations
    • Algorithmic trading strategy development
    • SOC-inspired routines: signals → correlations → decision
    • Strict risk management (R:R, drawdown, prop-firm rules)
    • Python scripts: analysis, journaling, monitoring
    • PineScript indicators (v5/v6)
    • Automated bots via API (Binance, Bybit, Bitget, brokers)

    ACHIEVEMENTS
    • Passed several prop-firm challenges (certificates)
    • Confirmed €5,000 payout
    • Tested and reproducible strategy models
    • PineScript indicators & signals
    • Python bots (Django / FastAPI) API connected
    • Dashboards, journals, and personal tools
    • Stable execution: Linux, logs, monitoring
