Market Internals

The language of the market. Before price moves, the internals speak. Learn to read them and you'll know what's coming — before it happens.

Derived from Mastering the Trade by John F. Carter

Why Internals Matter

Every single trading day presents setups on both the long side and the short side. Market internals tell you which days to ignore all short setups, which days to ignore all long setups, which days are pure chop — and which days are setting up for a violent reversal.

Price action alone is blind to what's happening beneath the surface. Internals reveal the conviction behind the move — whether buyers or sellers truly mean it.

The Four Questions Internals Answer

↑ Is this a day to only trade longs?
↓ Is this a day to only trade shorts?
~ Is this a chop day — fade extremes?
⚡ Is a violent reversal setting up?

The Six Core Internals

Carter's primary dashboard — read in this order every morning.

$TICK

Most Important

NYSE TICK

Measures the number of NYSE stocks ticking up minus those ticking down at any given moment. Carter calls it "the DJ of the market" — it reflects the immediate mood with more accuracy than any other single indicator.

Key Rules

Noise Zone –400 to +400 → ignore, no conviction

Watch Zone ±600 → attention required, conviction building

Action Zone ±1,000 → sustained = take action on your position

Extreme ±1,200–1,400 → something big is happening; do not fight it

Playbook

Bullish conviction: TICK consistently above zero, 5-period SMA crosses +500 and holds → stay long, add on pullbacks to 0.00 line

Bearish conviction: TICK consistently below zero, SMA below –500 → stay short, ignore long setups all day

Fade play: Quiet market suddenly spikes to ±1,000 → fade the move (first test often a head-fake)

Early exit rule: In a long and TICK hits –1,000, bounces to –500, then makes a new low → exit at market regardless of stop

Divergence: Price makes lower lows but TICK makes higher lows → watch for major bullish reversal

Rose's Setup Used alongside Phase Oscillator for confirmation. A PO cross with TICK above +600 and sustained = high-conviction entry. TICK at –1,000 with PO rolling over = avoid all long setups.

$TRIN

Volume Pressure

Arms Index (TRIN)

Tracks where volume is actually flowing. Formula: (Advancing Issues ÷ Declining Issues) ÷ (Advancing Volume ÷ Declining Volume). Below 1.0 = volume flowing into advancing stocks. Above 1.0 = volume flowing into declining stocks.

Key Rules

Rule #1 Don't care about the current reading in isolation — care about the trend

Bullish TRIN trending lower all day → ignore short setups

Bearish TRIN trending higher all day → ignore long setups

Daily Close Rule Closes above 2.0 → 80% chance of rally next day. Closes below 0.60 → 80% chance of selloff next day

Key Insight

A TRIN reading of 1.50 can be bullish if it opened at 2.0 and has been falling. A reading of 0.85 can be bearish if it opened at 0.45 and has been rising. Context and trend, not the number itself.

The biggest rallies happen when the TRIN hovers below 0.50 all day — "overbought" means nothing here. The trend continues.

Rose's Setup When TRIN is trending up and Pivot Ribbon is in bearish stack, those two together = strong short-only day filter.

$ADD

Breadth

NYSE Advance-Decline

Simply the number of advancing NYSE stocks minus the number of declining stocks at any moment. Measures the breadth of market participation — is the move broad or narrow?

Key Rules

Confirmation ADD and price both moving the same direction = broad, high-conviction move

Divergence Price makes new low, ADD makes higher low → major bullish reversal signal

Reversal signal ADD was dropping all day then suddenly turns sharply higher = distribution of selling pressure, rally incoming

How to Read It

Strong day: ADD pushing sharply higher confirms TICK readings. Both agree = high probability directional day.

Fake rally: Price rallies but ADD barely moves or stays negative → narrow breadth, likely to fail.

$VIX

Fear Gauge

CBOE Volatility Index

Measures the market's expectation of 30-day volatility. Known as "the fear index." The VIX moves inversely to the market and typically leads price — it breaks before the market breaks.

Key Rules

Intraday — Sell signal VIX making new highs on the day in a negative TICK environment → danger, exit longs

Intraday — Buy signal VIX rolls over and starts falling while TICK hits new day highs → strong reversal buy signal

Daily chart VIX closes above upper Bollinger Band (20,2) → market bottom forming, violent rally likely

Panic extreme VIX massively extended = selling has exhausted itself; don't get excited on the downside

Two Timeframes

5-min chart: Watch for breakout/breakdown moves. VIX breaks first — it's the tell. A VIX spike before a TICK breakdown is the earliest warning available.

Daily chart: Track Bollinger Band extremes. Extreme fear = capitulation = reversal. The flash crash, the 2018 vol blowup — all visible in VIX Bollinger extremes.

Rose's Setup VIX rolling over + TICK making new day highs = one of the cleanest high-conviction long entries. This is the short-covering rally setup Carter describes in Chapter 5.

$VOLSPD

Volume Diff

Up-Down Volume Difference

The S&P 500 Up-Down Volume Difference. Shows the net difference between the volume trading above vs. below yesterday's closing prices. Carter says this indicator is "worthless at the beginning of the day, but priceless into the last hour."

Key Rules

EOD only Most valuable in the final 60–90 minutes of trading

Bullish divergence Market selling off hard but VOLSPD grinds higher → market will reverse and rally into close

Bearish divergence Market rallying but VOLSPD making new lows → rally is a fake-out, expect sell into close

Primary Use Case

End-of-day fake-out filter. When the market sells off hard into close but VOLSPD stays positive, Carter fades the selloff. Similar to $ADD but volume-weighted — tells you where the big money is actually going.

$PCVA

Sentiment

Combined Put/Call Ratio

The combined equity and index put/call ratio. Measures total put volume divided by call volume across both retail (equity) and institutional (index) options — giving the best picture of overall market positioning.

Key Rules

Above 1.0 More puts than calls → bearish sentiment, potential short-covering setup forming

Well above 1.0 all day Extreme put buying = everyone already short = short-covering rally imminent

Contrarian signal When everyone is positioned the same way, the market traps them. High PCVA + capitulation TICK = reversal buy

The Trap Mechanic

When all 100 market participants are short, there's nobody left to sell. The market drifts higher, takes out tight stops, which triggers short-covering, which drives price into medium stops — cascade rally. High PCVA is your early warning that this trap is being set.

Carter's Reading Order

Scan in this sequence at the open, then monitor throughout the session.

$TRIN + $TRINQ

Which direction is volume flowing? Are both trending together or diverging?

→

$PCVA

What's the overall positioning? Is a short-covering setup loading up?

→

$TICK

What's the immediate conviction? Above or below zero? Any ±1,000 readings?

→

$ADD + $VOLSPD

Confirming breadth and volume direction? Or diverging from price?

→

$VIX

Is fear rising or falling? Making new highs or rolling over?

Day Type Filter

Use this to classify the day within the first 30–45 minutes.

Day Type	TICK Pattern	TRIN Pattern	VIX	Action
Bull Trend	90%+ of time above zero, repeated +1,000 hits	Trending lower all day, making new lows	Declining, making new lows	Long only. Buy pullbacks to TICK 0.00 line.
Bear Trend	90%+ of time below zero, repeated –1,000 hits	Trending higher all day, making new highs	Rising, making new highs	Short only. Sell rallies back to TICK 0.00 line.
Chop	Whipping ±400, no sustained extremes	Mixed / no clear trend	Flat	Fade extreme TICK readings. Reduce size. Avoid breakout trades.
Reversal	Price new lows but TICK higher lows (divergence)	Extended high reading starting to curl lower	Spike then rolls over sharply	Watch for short-covering rally setup. VIX rollover + TICK surge = entry.
Panic / Crash	Hanging below –1,200 for extended periods	Making extreme new highs	Exploding higher, making new highs continuously	Do not buy the dip. Something is blowing up. Sit on hands or short.
