DoubleTrends™ launched on June 7, 2026 with 2 votes.

What it does

DoubleTrends tracks the S&P 500 and delivers a low-frequency, rules-based oversold-reversal signal through Telegram, with public research, signal history, and method pages on its website.

A quantitative S&P 500 market regime signal for ETF investors. Rules over noise, discipline over hype — live replay and full signal history from 2016.

A quantitative research firm helping S&P 500 investors navigate selloffs with rules and evidence, not noise. Point-in-time replay of the DoubleTrends™ signal from July 2016 onward. On each date, the system only sees data available at that point — no future information. The rule fired at every major stress event in this window: 2018 Q4, the COVID crash, the 2022 bear-market low, the 2025 tariff crash, and the March–April 2026 Iran war selloff. Point-in-time causal replay: on each date the system only sees data available back then, not future frames. Every DoubleTrends™ signal since 2004 with 90-day, 1-year, and 2-year forward S&P 500 returns. Outcomes shown as they stand at query…from doubletrends.com

    Read the Tape gives players the same 5 S&P500 stock charts per day to predict. You select low, medium or high confidence and then call the chart UP or DOWN. It's a 1d chart which then resolves over 5 days. Alpha is scored against the Monkey Index, a basket of 11 random coin flips at low confidence which provides a tangible win/lose condition. We're two weeks in and some interesting data is being kicked up. Players like to call tops even though stonks go up- 60% of the 70 charts so far resolve higher, players' down calls have only been right 31% of the time. There's a full stats dive at…

  • Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  • Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
