How Options Flow Scoring Works
Learn how Flow Proof scores every options trade for institutional conviction using 20+ signals including size, urgency, and repeat activity.
What is this?
Options flow scoring assigns a conviction rating to every institutional options trade based on multiple independent signals. The goal is to answer one question: how likely is this trade to represent informed, directional positioning rather than hedging, market-making, or noise?
The Multi-Signal Approach
A single data point — like trade size — is insufficient to determine conviction. A 5,000-contract call purchase could be a directional bet, a hedge against a short stock position, or one leg of a multi-leg spread. Flow scoring solves this by evaluating each trade across 20+ dimensions simultaneously and producing a composite score that reflects the overall probability of informed positioning.
The Core Signals
The key signals in conviction scoring include: absolute premium size (institutional-grade starts at $500K+), volume relative to open interest (above 1.0 indicates new positions being opened), execution type (sweeps indicate urgency, blocks may be hedges), bid/ask side (ask-side = aggressive buyer, bid-side = aggressive seller), repeat activity (same strike hit multiple times suggests systematic accumulation), DTE range (6-183 days filters out 0DTE gambling and LEAPS hedging), OTM percentage (0-15% filters out deep OTM lottery tickets), dark pool confirmation, and single-leg vs multi-leg detection.
The Score Scale
Scores range from 1 (almost certainly noise) to 10 (highest possible conviction). Trades scoring 7+ receive a "STRONG" verdict and are automatically paper-traded. Trades scoring 5-6 are "WATCH" — worth monitoring but not acting on alone. Below 5 is "SKIP." This tiered system lets you focus your attention on the 10-15% of flow that matters.
Why does it matter?
Without scoring, raw options flow data is a fire hose of noise. Thousands of institutional trades execute every hour, and the vast majority carry no actionable directional signal. Scoring transforms this chaos into a curated feed of the trades most likely to precede stock moves.
The Noise Problem
On any given day, the options market generates tens of thousands of trades that meet basic size thresholds. Market makers adjusting delta, funds rolling positions, portfolio hedging programs, and complex multi-leg strategies all create volume that looks "unusual" to the naked eye. Without multi-dimensional scoring, a trader looking at raw flow would spend hours sifting through trades that look significant but carry zero directional information.
Why Multi-Signal Scoring Works
Each individual signal has limitations. Trade size alone can't distinguish a directional bet from a hedge. Bid/ask side alone can't identify whether a trade is opening or closing. Sweep detection alone can't tell you if the position is a standalone bet or part of a spread. But when multiple signals align — large size + ask-side + sweep + volume exceeding OI + no earnings imminent + repeat activity — the probability of informed directional positioning rises dramatically. Conviction scoring exploits this convergence.
Transparency vs Black-Box
Some platforms use "AI" scoring without explaining what drives the score. Flow Proof's scoring breaks down every component so you can see exactly why a trade scored high or low. This transparency builds trust and helps you develop your own flow-reading skills over time rather than blindly following an opaque algorithm.
How Flow Proof helps
Flow Proof's scoring engine processes every options transaction in real time, evaluating it against the 20+ signal framework and producing a conviction score within milliseconds.
Pre-Filtering: The Filter Bible
Before scoring begins, trades pass through the "Filter Bible" — a set of institutional-grade filters that eliminate ~90% of all activity. Only ask-side trades, $500K+ premium, sweep or block execution, single-leg only, stock (not ETF) options, and volume exceeding open interest survive. This pre-filtering dramatically improves signal quality before the scoring engine even runs.
Real-Time Scoring Pipeline
Each surviving trade is scored across all signal dimensions. The engine checks trade size relative to the specific contract's open interest (not generic thresholds), classifies execution type and fill patterns, detects dark pool routing, identifies repeat activity patterns, and cross-references with upcoming catalysts. The result is a 1-10 score with a full breakdown showing exactly which signals fired and which didn't.
Automated Paper Trading for Validation
Here's what makes Flow Proof's approach unique: every trade scoring 7+ is automatically paper-traded. This creates a live, auditable performance journal that validates whether the scoring system actually identifies profitable trades. Over weeks and months, this journal builds a statistically meaningful sample — you can see the win rate, average return, and holding period for high-conviction signals before risking real capital. This evidence-based validation is something no other flow platform offers.
