The Science Behind Similarity Search

Our approach is rooted in the understanding that market behavior often reflects human emotional patterns. We all wake up at the same time, eat lunch at the same time, get tired at the same time, etc. And just like our daily routines follow predictable rhythms, stock prices fluctuate in recognizable waves. This is why intraday studies are useful, and Similarity Search translates these emotional currents into actionable data.

🚀 To the Moon: SimSearch is not available anywhere but BigShort!


How to Access Similarity Search

In the BigShort app, click on UltraFlow in the side menu. From there, choose which UltraFlow you’d like to view at the top left of the screen under the date search. From there, click the Similarity Search (beta) button next to the historical button. At the bottom of the BigShort chart, you’ll now see the 5 dates with the most similar price patterns to today’s, as well as the SS median line, which is the median of all 5 days. Click on the dates to toggle them on and off.

How Similarity Search Works

  • Activates 30 minutes after market open

  • Updates every 2 seconds for real-time analysis

  • Continuously refines results as more data points come in

Key Features

  • Displays 5 most similar historical trading days

  • Provides a median trend line for comparative analysis

  • Covers major index ETFs: SPY (S&P 500), QQQ (Nasdaq 100), DIA (Dow Jones)

Interpreting the Chart

  • Unified directional trends in all historical days suggest stronger predictive power

  • Divergent patterns in historical days indicate higher market uncertainty

UltraFlow Explained

UltraFlow aggregates indicator data from all the individual constituents of an ETF. For example, SPY UltraFlow combines SmartFlow, Manipulation, and Net Option Flow data for every ticker in the S&P 500 into a single chart.

Best Practices

We recommend using Similarity Search in conjunction with our Net Option Flow indicator to fine-tune your entry and exit points.
