I design systems to stay consistent across market regimes, withstand noise, slippage, latency, and partial fills, avoid overfitting, degrade gracefully when assumptions fail, and handle real-world edge cases like gaps, spikes, and low liquidity. ✅ Trading Platforms & Execution • NT7 / NT8 strategies, indicators, trading panels, licensing • MT4 / MT5 indicators, Expert Advisors, Tickstory & QuantDataManager (99.90% backtests) • TradingView Pine Script indicators, strategies, screeners, alert webhook bridge • MultiCharts, QuantTower, Sierra Chart, Thinkorswim, Charles Schwab • IBKR TWS & IB Gateway API trading ✅ Backtesting & Quant Research • QuantConnect, VectorBT, Backtrader strategy backtesting, risk analysis • AI / RL strategy development (SB3, Gymnasium, SAC / PPO / A2C) ✅ Risk Analysis & Risk Management • Pre-trade risk checks (position limits, leverage) • Real-time P&L, drawdown & exposure monitoring with kill switches • Liquidity & execution risk (slippage, widening spread, commission, exchange fee) • Strategy risk validation (overfitting detection, walk-forward testing) ✅ Market Data & APIs • Stock market API integration & subscription cost optimization (IQFeed, DxFeed, Massive, AlphaVantage) ✅ Infrastructure & Data Systems • Time-series databases & tools: QuestDB, InfluxDB, TimescaleDB, ClickHouse, kdb+, • Kafka, Redis, Grafana ✅ Products & Monitoring • Trading product licensing • Copy trading systems • Trading performance monitoring dashboards ✅ Visualization & UX • Charting applications in C# Avalonia ✅ Sustainability & Discipline • Consistency, eyesight protection, and burnout-avoidance guidance ==================================================================================== "I believe the current trade I am in will be a loser ... a big loser at that." Larry Williams "If a trader is motivated by the money, then it is the wrong reason. A truly successful trader has got to be involved and into the trading, the money is the side issue… The principle motivation is not the trappings of success. It’s usually the by-product – simply stated, 'the game’s the thing'." Bill Lipschutz "Don’t focus on making money, focus on protecting what you have." Paul Tudor Jones "Losing is extremely important. Winning’s easy. Losing is the key to trading." John Moulton "In trading, you have to be defensive and aggressive at the same time. If you are not aggressive, you are not going to make money, and if you are not defensive, you are not going to keep the money." Ray Dalio "Amateurs think about how much money they can make. Professionals think about how much money they could lose." Jack Schwager daha az
