About US Stock Sigma
US Stock Sigma is a TradingView indicator built for traders who want to see what the options market is actually pricing in — not what a price-only oscillator thinks happened yesterday.
What we do
We compute Expected Move ranges (±1σ), Call/Put Wall levels, Gamma Flip, and gamma exposure metrics for the heavily-traded US tickers traders actually use. The output is delivered as an invite-only TradingView indicator that overlays directly on your chart.
Why options-derived data
Most chart indicators are lagging by design — they react to price. Options markets price the future: implied volatility tells you how much movement professionals are paying for, and open interest at specific strikes reveals where dealer hedging concentrates. That information is invisible to traders who only watch the candle chart.
Who we are
US Stock Sigma is operated by Sigma Tech Communications LLC, a Virginia-based technology company. We build practical analytical tools for active traders. The Korean-language version of this service (usstocksigma.com) has served the Korean retail options community since 2025.
