What is a sync day?

All four institutional legs moved the same way today (session-over-session deltas):

Client (retail) is on the opposite side — structurally true on every sync day in our data.

When to take it

1
4-leg sync — all institutional legs agree
2
High conviction — institutional activity in top quartile
3
Gap WITH — next open gaps in positioning direction
4
Normal gap — overnight move under 0.5% (skip wide news gaps)
5
Hold toward close — full day beats open scalp on Dhan data

Extra footsteps toward 8/10

Tested on top of the base stack above. Small samples — treat as filters, not guarantees.

DII opposite (F&O delta vs FII+Pro)6/7 (86%)
Options-led (opts > fut magnitude)7/9 (78%)
Combo opt-led + DII opp + Wed–Fri5/6 (83%)
DII WITH institution0/2 (skip)
FII 2-day persist alone38% (no edge)

Stretch stack: Above + DII opposite + options-led + avoid Mon/Tue signal → 5–6/7 (~83%) hold-to-close. ~~6 trades/year (fewer, sharper).

6th footstep — not wired yet

FII cash-market net (NSE FII/DII cash, not F&O). Stage 1 already knows this leg — cash agreeing with F&O direction is the full institutional picture. Needs a daily number from you when NSE blocks the server.

Triangle when live: FII+Pro F&O sync · Client opposite · DII opposite · Cash confirms.

When to stand aside

Gap AGAINST positioning at the open — shakeout day. Overnight hit rate 0% with positioning in our sample.

Waiting for 12:15 only recovers ~52% on those days — not enough edge. Full day is worse (~31%).

Do not trust the open on gap-against sync days.

Dhan numbers (honest)

All sync · overnight40/69 (58%)
Gap WITH · full day26/40 (65%)
Gap AGAINST · 12:1515/29 (52%)
Gap AGAINST · full day9/29 (31%)
Best stack · full day9/12 (75%)

High conviction + gap WITH + |gap| < 0.5% → hold to close. Roughly ~9 setups/year.

Core test

Did price act as per positioning? Measure from signal-day closenext session. The edge is in which days you take and which clock — not trading every sync day at the open.
