Technical Analysis Signal Lab (2D)

A live candlestick tape, generated bar by bar with geometric Brownian motion, rendered as a flat 2D chart: candle bodies with high/low wicks, a fast and slow simple moving average tracing over the top, and a 14-period RSI oscillator running in its own panel below. Adjust the moving-average periods, volatility and drift, drag the chart to scroll back through the recorded history, and watch the simulator call genuine golden-cross, death-cross, overbought and oversold signals exactly the way a technical analyst reads a real chart — the same formulas, on synthetic data.
