Follow the big money in options. Options Sentiment Screener tracks unusual options activity across the US market and turns it into one clean, fast terminal: the live tape, the whale trades, the put call ratio and the sentiment behind it all. PULSE Open the app and see the day in one screen: net bullish versus bearish premium across every unusual print tracked today, call and put premium, the put call ratio, sweep share, the top tickers by unusual premium and the whale of the day. FLOW The live tape of unusual options activity. Every print shows the contract, size, open interest and premium, color coded by sentiment. One tap filters for calls, puts, sweeps, bullish, bearish, premium size and weekly expiry. Tap any print for the full detail: execution, bid and ask, spread position and the underlying quote. WHALES The biggest trades of the day and the week, ranked. Million dollar prints carry the WHALE tag, and a conviction score weighs premium size, size versus open interest, sweeps and execution so the prints that matter stand out from the noise.

Chart Echo turns chart-reading into a guided hunt. Frame a pattern on any stock or crypto chart, and Chart Echo searches decades of market history for the setups that looked just like it — then shows you, statistically, what happened next. A deck of cards walks you through it: • Market — pick a stock or crypto, or start from a popular ticker. • Frame — set the window of candles that defines your pattern. • Matches — browse the closest historical echoes, ranked by similarity. • The Echo — overlay a match and read the outcome: bullish/bearish bias, confidence, trend and volatility context.• Act — save the workspace, set an alert, or share a Story. Premium unlocks intraday timeframes, unlimited searches, saved workspaces synced across devices, watermark-free Story exports, and unlimited pattern alerts. Chart Echo is a research and education tool. It is not financial advice, and no pattern match, score, or projection is a recommendation to buy or sell. Markets are risky and you can lose money — always do your own research. Terms of Use (EULA): https://chart-echo.com/terms
