QUICK REFERENCE
Core Indicators
TICKNYSE upticks − downticks
TICK = (stocks↑) − (stocks↓)
−10000+1000
< −800/−1000extreme sell pressure
−300 to +300balanced / chop
> +800/+1000extreme buy pressure
Real-time. Best for timing, not trend. Watch for divergence at new price highs/lows.
ADDAdvance − decline (issues)
ADD = advancers − decliners
neg0pos
falling linenarrowing participation
flat / choppyno clear breadth trend
rising linebroad participation
Track the cumulative line vs. price. Divergence = leading indicator, plays out over days–weeks.
VOLDUp volume − down volume
VOLD = vol(up stocks) − vol(down stocks)
neg0pos
neg / falling$ leaving, distribution
disagrees w/ ADDcheck concentration
pos / rising$ backing the move
Best conviction proxy — where the money actually is, not just headcount.
TRINArms Index (volume/breadth ratio)
TRIN = (adv/dec) ÷ (upVol/dnVol)
<0.51.0>2.0
< 0.5euphoric — climax risk
0.8 – 1.2balanced flow
> 2.0panic — bounce risk
Reads contrarian at extremes. <1 = buy-side conviction; >1 = sell-side conviction.
MCCLELLAN OSC / SUMMATIONSmoothed breadth momentum
Osc = EMA(19) of net advances − EMA(39) of net advances · Summation = running total of Osc
Osc < −100oversold, short-term
zero-line crossmomentum shift trigger
Osc > +100overbought, short-term
Use Oscillator for days–weeks momentum; use Summation Index trend for the intermediate-term "market health" read (weeks–months).

0DTE / Intraday Workflow
1Opening tone — read TICK + TRIN behavior in the first 15–30 min for initial buy/sell aggression.
2Mark the level — VWAP, prior day H/L, first-hour H/L, or a known S/R zone.
3Wait for a trigger — price at the level + TICK divergence + TRIN drifting toward/away from 1.0, together — not one signal alone.
4Respect gamma risk — decay/gamma accelerate sharply in the final 30–60 min; internals time entries, they don't manage that risk.
DEALERS LONG GAMMA

Hedging dampens moves → range-bound, mean-reverting tape. TICK/TRIN extremes tend to snap back — favors fade setups.

DEALERS SHORT GAMMA

Hedging adds to moves → faster, sustained trends. TICK/TRIN extremes tend to persist/accelerate — favors continuation setups.
