Our Domain-Prior WeightingBearish
7 bullish / 5 bearish rows
FII 40% / PRO 30% / DII 15% / RETAIL -15% — for comparison only, not what drives the live bias. Agrees with the account's own call 85.4% of the time historically; both score ~52% hard-day accuracy (coin-flip) when backtested independently.
⚠️ The account's own call and our weighting disagree today — the live bias uses the account's own call (left).

Yesterday's Predicted vs Next-Day Outcome (Last 2 Months)
Day-by-day record of strategy prediction issued on D_(t-1) vs actual Nifty move on D_t
Domain-prior weights (not data-fitted): FII (+40%), PRO (+30%), DII (+15%), RETAIL (-15% contrarian) · threshold 0.10 — see the Weight Optimization tab for why a data-fitted alternative was rejected
FII Weight+40%
+40%
Foreign Institutional Investors โ smart-money prior, largest weight
These weights are a domain prior, not fit to this data. A data-driven grid search was tried
and rejected: it initially found FII at -40% (negative), which turned out to be a
collinearity artifact (FII and RETAIL correlate at -0.69 in this sample, so the optimizer could
extract the same predictive value from either sign on either one). Every individual
participant/instrument reading correlates with next-day return at under 0.12 in magnitude —
below the ~0.075 noise floor at this sample size. When re-run constrained to respect
FII/PRO/DII ≥ 0 and RETAIL ≤ 0, out-of-sample accuracy collapsed to
38.9% (worse than a coin flip) — see the Weight Optimization tab for the full breakdown.
Account's own call vs. our weighting — which is actually better?
A separate bug meant this dashboard's live bias was silently using our own weighted computation
even when it disagreed with @fii_dii_data17's own stated "OVERALL TREND" call in the image (now
fixed — the live bias uses the account's own words). The two signals agree
85.4% of the time across
178 posts. Backtested independently, neither
clearly beats the other: the account's own call scores
51.9%
hard-day accuracy and 79.2%
option-seller win rate; our domain-prior weighting scores
51.9%
hard-day accuracy and 77.0%
option-seller win rate — both essentially a coin flip. With no statistical reason to prefer
our derived approximation over the account's own real, verifiable statement, using their words
directly is the more defensible and more transparent choice.

FII/PRO/DII/RETAIL Weight Optimization Experiment
Option-seller scoring: a call only loses if Nifty moves >0.6% against it · ranked by hard-day accuracy, not raw win rate · target 75%
Target AccuracyGoal
75.0%
Requested target, measured on hard-day accuracy (see below)
Constant-Bias Free BaselineNo signal used

Always calling Bullish (or Bearish) wins this often on raw win rate alone — big adverse moves are rare
Unconstrained Fit: Test Hard-Day72.2% Test
72.2%
Looked good... until sign-constrained (see next card)
Honest read: why the unconstrained fit was rejected
Scoring matches how an option seller actually gets paid: a directional call only loses if
Nifty moves against it by more than 0.6%. That makes raw win rate misleading (a constant
"always Bullish" call already wins ~78% for free), so
candidates are ranked by hard-day accuracy instead — directional accuracy on just the
days that actually moved >0.6%, where a constant bias scores ~50% (a coin flip).
The first (unconstrained) pass found a combo scoring
72.2% out-of-sample — but it did
so by weighting FII negative, which read as backwards given how central FII flow is
supposed to be. Digging in: FII and RETAIL correlate at -0.69 in this 178-day sample, and
every single participant/instrument reading correlates with next-day return at under 0.12 in
magnitude (the noise floor at this sample size is ~0.075). That combination — strong
collinearity, no real univariate signal anywhere — is exactly the setup where an
unconstrained fit finds spurious sign flips instead of real relationships.
Re-running the search constrained to FII/PRO/DII ≥ 0 and RETAIL ≤ 0
(respecting the "smart money helps, retail is contrarian" prior) confirmed it: out-of-sample
accuracy collapsed to 38.9%
— worse than guessing. The live model has been reverted to a domain-prior weighting
(FII 40% / PRO 30% / DII 15% / RETAIL -15%, not fit to this data at all), which scores an
unremarkable but stable ~50-52% hard-day accuracy across train/test/full — consistent
with genuinely having no measurable edge yet on this data, rather than a fit-then-collapse
pattern. 75% is not reachable honestly at this sample size; more history is needed before this
signal can be trusted to override an intuitive prior in either direction.

Read before using
Strikes and premiums above are pulled live from the Fyers option chain, not the synthetic
placeholder table used elsewhere on this dashboard. Lot size is hardcoded at 65 — verify
against the current NSE Nifty lot size before sizing a real trade. Strikes here are chosen to
hit ≥1:1 reward-to-risk, which is a different (harder, lower-probability) bet than the
wider, higher-win-rate structure the FII/DII backtest tabs describe — see the "implied
cushion" card above for this specific structure's own backtested numbers. This is a systematic
tool output, not investment advice; size and manage risk according to your own judgment.
