Flow Analysis: Reading the Smart Money

5 min read · Smart Money

Every day, institutional investors place billions of dollars in options and stock orders. Most of this activity is invisible to retail traders — but not all of it. Flow analysis is the practice of tracking these institutional footprints.

What Is "Flow"?

In trading, "flow" refers to the real-time stream of orders hitting the market. When we say "smart money flow," we mean orders from institutions — hedge funds, prop desks, and large asset managers — that are too big to hide completely.

What We Track

Signl monitors two primary flow channels:

1. Options Sweeps

A sweep order is when someone needs to fill a large options position immediately, so urgently that they sweep across multiple exchanges simultaneously. This signals conviction — they're willing to pay premium for speed.

• Call sweeps = bullish conviction (betting the stock goes up)
• Put sweeps = bearish conviction (betting the stock goes down)
• Premium size = how much skin is in the game ($500K+ = serious)

2. Dark Pool Prints

Large block trades executed on private exchanges (dark pools). When we see a cluster of prints at or above the ask price, it means someone is aggressively buying. Learn more about dark pools →

From Flow to Signal

Raw flow data is noisy. Signl filters it through several layers:

• Size filter — Only whale-sized trades (>$500K premium)
• Clustering — Multiple flow events on the same ticker within a window
• Direction alignment — Are calls and dark pool prints both bullish?
• AI analysis — Technical chart analysis + fundamental context scored by AI

The Flow Radar

The Flow Radar on your dashboard shows today's institutional activity in real-time. Each row represents a significant flow event with its premium, direction, and the AI's assessment of whether it aligns with the current technical setup.
