COA-1 Chain OI Alignment—
COA-2 Combined Option Assessment—
50 is neutral. Above 58 / below 42 on both indexes indicates directional alignment; live signals require a stricter 63 / 37 gate, two earlier confirming snapshots, acceptable spreads and volume. These scores are NOT trade accuracy percentages or another software's proprietary COA formulas.

Six transparent reversal reference levels
Our independent premium bands around last traded option premium: R1/R2/R3 above and S1/S2/S3 below. Formula uses 2%, observed bid/ask spread and a minimum ₹0.05 movement. These are model bands, not guaranteed reversals.

This uses OI, positive Change OI and cumulative volume ranks; it is an original experimental approach, not Vinay Sir's undisclosed formula. Scores are not accuracy probabilities.

Percentage changes use the previous close reported by the data provider. Demo mode is fictional. No percentage score represents a probability of success.
Replay Game of Percentage
RECORDED DATA ONLYOpen History & Accuracy, load recorded sessions and step/play; the percentage lab will update using each recorded frame, without looking at later frames. When an entry/target/stop threshold is crossed in replay, a historical announcement appears. Missing prices between REST observations cannot be reconstructed.
Replay not started.
Live option tick stream
UPSTOX V3 WEBSOCKET · SERVER WORKERSelect an exact subscribed Upstox contract instrument key (not the underlying symbol). The browser refreshes saved server ticks approximately once per second; no trading orders are submitted. A stale badge means the worker or market may be inactive.
Enter a subscribed instrument key to begin.
Tick chart is read-only. Stream updates occur when Upstox publishes an update, not at an artificial constant rate. Internet gaps mean missed ticks.
RECORDED SPOT + OI/VOLUME LEVELS
Support / Resistance Shifting Chart
● Spot● Support 1 / 2● Resistance 1 / 2▲ WTB / ▼ WTT
The chart uses real saved snapshots only, not fictional historical candles. A shift appears when the best-ranked level changes between observations.
Level movement and WTB / WTT readings appear after data loads.
Shifting level events
SNAPSHOT-TO-SNAPSHOT| Time (IST) | Level | Previous | New | Shift | Weakness reading |
|---|---|---|---|---|---|
| No recorded shifts loaded | |||||
WTB (Weakness at Bottom): spot in the lower 25% of the measured support–resistance channel AND bullish normalized OI/volume imbalance. WTT (Weakness at Top): spot in the upper 25% AND bearish imbalance. These are original experimental definitions, not Vinay Sir's private formula. No guarantee of reversal or trend continuation.
BROKER GREEKS + INDEPENDENT BLACK–SCHOLES
Choose a CE/PE LTPOption Greeks & target-premium lab
Black–Scholes is a theoretical European-option model. Delta, Gamma, Vega (per 1 IV percentage point), Theta (per day), Rho (per 1 interest-rate percentage point). Model prices differ from executable LTP and may be inaccurate near expiry or during jumps; Greeks are local sensitivities, not fixed future price forecasts.

Replayed observations reproduce collected REST snapshots, not intraperiod highs/lows. If you did not record a trading day, it cannot be reconstructed from the normal option-chain API. Playback does not imply trade execution or proven accuracy. The timeline can be inspected freely; simulated signal announcements arise only from the current and earlier frames.
Historical signal evaluation
Only real stored Upstox snapshots qualify. Demo data never counts.
90% observed win rate is a research target, not a guaranteed result. At least 100 closed real-data evaluations are required before comparing the observed rate with that goal; a 95% confidence interval and later out-of-sample validation are also necessary. Entry only after a later saved quote crosses the trigger; exit uses observed bid or LTP. Requires snapshots over time; missed intraperiod stop/target moves, transaction costs and slippage may distort outcomes.
