Money Flow and Options Flow Analysis: Reading UOA with $ASTS Example

I'll pull the live options-flow data on $ASTS — trade-level unusual activity, strike/expiration walls, and the day-over-day flow trend — so we can teach the methodology on real numbersHere's a practical walkthrough of money flow / options flow analysis and how to read Unusual Options Activity (UOA) — taught on $ASTS's actual latest data (Friday, 8/21/26; platform recorded 20 unusual trades that day).

Part 1 — What "Money Flow" & "Options Flow" Analysis Actually Is

Money flow tracks where smart money is placing premium — the dollar amount of options traded, aggregated and classified, rather than just watching candles. Think of it as radar behind the price action.

The single most important rule — direction is determined by Action × Type, never by call/put alone. This is the #1 amateur mistake:

So a "bought call" and a "sold call" mean opposite things, even though both are "calls."

Three lenses of flow analysis (each answers a different question):

1. UOA (trade-level): what did big individual trades do? (urgency, side, freshness)
2. Strike/expiration walls (aggregated): where is premium concentrated at specific strikes & expirations? (magnet levels)
3. Time series: is the flow strengthening or weakening day over day? (momentum of conviction)

Part 2 — How to Read UOA: The Signal Hierarchy (with $ASTS trades as examples)

Read every trade through 6 layers, in this order:

Layer 1 — Action × Type (direction). Never infer from the contract type alone. Layer 2 — Sweep vs Block (urgency).

• Sweep = trader crossed multiple exchanges to fill right now, paying spread cost → urgent, conviction-laden
• Block = negotiated desk-to-desk → often institutional hedging or position management, lower urgency
• Rank sweeps above blocks for short-term directional signal.

Layer 3 — Moneyness + DTE (intent).

• Far-OTM + short-DTE = speculative conviction (needs a fast move)
• ATM/mid-DTE = standard swing positioning
• ITM + long-DTE = likely hedge/position adjustment, not a naked directional bet

Layer 4 — Size vs Open Interest (freshness).

• Size >> OI = FRESH position being opened → high signal
• Size << OI = likely closing/adjusting an existing position → low signal

Layer 5 — Repeats (accumulation). Multiple trades at the same strike+expiry = someone systematically building → stronger than any single large trade.

Layer 6 — Premium ≠ Conviction. A $295K trade can be a closing sale; a $26K sweep can be a fresh high-conviction bet. Always cross-reference premium + action + type + moneyness + DTE + style.

Part 3 — Applied to $ASTS (8/21/26)

Sentiment Overview — the day was nearly balanced

• Bullish share 48.1% / Bearish share 51.9% — essentially neutral, slight bearish tilt
• Net premium −$48K ($592K bullish vs $640K bearish out of ~$1.23M total) | Ratio 0.92
• For scale: $1.2M/day on a mid-cap like $ASTS is meaningful but not whale-scale — and on Friday the market was block-dominant (sweepShare only 31%), meaning the day's flow was institutional/negotiated, not urgent.

Top Signals of the Day (the "why" matters, not just the "what")

Strike Clustering — the $70 Wall

The chart shows where premium clumped by strike (bullish orange vs bearish blue):

[ASTS strike walls 8/21 — the $70 zone is the battle line]

• Largest call wall: $70 (~$425K combined premium) → that's your magnet/resistance. Dealers who sold $70 calls hedge by selling stock as price approaches — self-fulfilling ceiling.
• $75 is the runner-up wall → second overhead level.
• Put walls at $60/$65 (sold puts) and the $140P adjustment are support/income references, not scattering systematically.
• Crucially: price sits just below $70 — the entire day's debate happened underneath that wall.

Expiration Focus — the "when" tells you the thesis

• Near-term (9/18, 10/16): sweeps bought at $70/$75 + $85C sold → traders positioning for a Sept/Oct catalyst window, mixed with local capping
• Long-dated (2027–2028): block buying of $75C/$105C/$115C + leap call selling at $70 → institutions building long-term upside while others harvest premium overhead
• The mix of near-term sweeps + long-term blocks = "short-term speculation layered on long-term positioning."

Time Series — is the flow strengthening or fading? (the 11-day trend)

[ASTS net options flow per day — the momentum picture]

• Range totals (8/7→8/21): net +$14.68M, bullish share 66.8% — looks strongly bullish on the surface
• But the engine was put SELLING ($21.6M) vs call BUYING ($7.6M) → income/willingness-to-own flow, the milder form of bullishness. $12.8M of it came in one day (8/10) as urgent put selling
• strongSweepNet (urgent money) was net-call-buying every single day — never flipped sign — but magnitudes are small (max ~$477K)
• Trend vs snapshot conflict: the 11-day snapshot is 67% bullish, but Friday flipped to ~50/50 with call selling dominating — momentum is cooling into the weekend. Bullish share path: 71% → 83% → ... → 60% → 71% → 48% (Friday)
• Per the flow playbook: the trend is the signal; the snapshot is stale positioning. Right now they diverge slightly.

Spot Context — where price sits vs the flows

• $ASTS closed Friday $68.11 (range $64.90–$70.10); recovered off the July low ($53) but still below SMA50 ($70.24), SMA100 ($79.89), SMA200 ($82.11) and below the Ichimoku cloud (Span A $73.25) — a repair phase, not a new uptrend yet
• RSI ~50, MACD histogram expanding above zero (+0.36) — momentum improving but not confirmed
• The read: the $70 zone = SMA50 + largest call wall + a round number → triple confluence ceiling. Buyers aggressively swept $70/$75 calls near-term (want a break), while overhead call sellers at $70–85 (long-dated) say "not yet." Clean, readable battle.

Part 3 — UOA Reading Cheat Sheet (the 7 rules)

1. "Call = bullish" is a trap. Action × Type is the only truth. Sold call ≠ call buyer.
2. Sweep beats block for short-term conviction — urgency is priced into the execution style.
3. Moneyness + DTE = intent. Far-OTM short DTE = speculation; ITM long DTE = hedge/adjustment. Flags: treat the $140P ITM repeat as position management, not a market call.
4. Size vs OI separates fresh from closing. Size >> OI = new money (signal). Size << OI = old position being managed (noise). The $295K $70C sale fails freshness — it's an exit/cover, so don't over-credit it.
5. Repeats = accumulation. Same strike+expiry traded twice or more = systematic build, higher conviction than any single print.
6. Premium ≠ conviction. Always decompose: premium + action + type + moneyness + DTE + sweep/block = the real signal.
7. Anchors to spot. Calls above spot bought = upside positioning; calls at/below spot sold = ceiling. The $70 wall matters because price is $68.1, not in a vacuum.

Takeaway on $ASTS: Friday's flow was a balanced, institutional-grade pause under the $70 magnet wall — near-term upside bets at $70/$75 vs long-dated overhead supply at $70–85 and a $140P hedge adjustment. The 11-day window was net bullish but built on put-selling income (mild conviction) with urgency small and consistent. Price hasn't taken out the wall yet; until it does, the flow says respect the $70 ceiling and the $65–64.9 support ledge.
