Day 4 of the #30DayChartChallenge: Slope 📊
On April 8, 2026, the S&P 500 index (^GSPC) showed a significant increase, closing at 6,782.81. This increase was mainly driven by the ceasefire agreement between the United States and Iran.

I'm sharing one of the charts generated and included in the 19-page technical report: S&P 500 (^GSPC), analysis window = 365 - generated April 04, 2026 at 07:08 PM.
#python #stocks #sp500 #dataviz

SMA, BB, MACD, RSI, Fibonacci, Monte Carlo, ATR, OBV, Stochastic, ADX - adapting its methodology to the chosen analysis horizon and produces a transparent weighted scoring verdict.
All formulas follow Wilder's 1978 exact specifications (RSI, ATR, ADX) - values match TradingView and Bloomberg.

I built a Python framework for technical analysis reports: 10 indicators, adaptive scoring by time horizon, transparent verdict w/ full methodology table.
