Tap an option premium to open the Greeks and scenario lab. R1 = current LTP + max(2% of LTP, 75% of spread, ₹0.05). R2/R3 and downward reference bands are available in the selected-contract details.
Independent signal confirmation; both models must agree to issue a hypothetical setup. Market conditions can change suddenly.
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.
Choose a contract to calculate.
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 ONLY
Open 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 WORKER
Select 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.
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.

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
Option Greeks & target-premium lab
Choose a CE/PE LTP
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.
