Understand the core logic, step by step

Watch the scanner's core logic in 8 short animated steps: the BEP dividing line, the strikes it looks at, the rules, the 5-minute close, the trend, Sideways and key supports, and what reaches you. Example numbers only. The scanner shows rule results only. It does not give Buy / Sell / Hold advice.

How it works

One shared live feed is evaluated every few seconds. Every client sees the same numbers and the same reasons at the same time. Here is the whole idea, step by step: the levels, the BEP line, the four rule checks, the strength grades, the option chain table, the synthetic future, and when you are told.

1 · Every option has a set of levels

For each strike, the call and the put are plotted with the same fixed levels, taken from the previous day and from today’s first minutes. The scanner uses exactly these numbers. Below is one call option (illustration from an earlier session — the numbers change every day).

1. H Res — a resistance zone built from previous-day highs.
2. Uni Res — the “universal” resistance: one line, common to every strike.
3. Equilibrium — the middle of the strike’s previous-day range.
4. Opp H — the opposite option’s first 5-minute candle high today.
5. PDC — this option’s previous-day close.
6. PDL — this option’s previous-day low.
7. Common BEP — the break-even premium. The key yardstick: the same line on every strike.
8. Today Open — where this option opened today.
9. L Sup — a support zone built from previous-day lows.

On the put chart you also see Opp L (the opposite option’s first-candle low) and Uni Sup (the universal support line) — the mirror of Opp H and Uni Res.

2 · The synthetic future and its levels

The ATM call and put are combined into an index-like number, the synthetic future, and drawn on the Nifty chart with its own levels. If it trades below its Today Open, Mid S&R and BEP the trend reads DOWNTREND; above all three, UPTREND. An alert that goes against this trend is still sent, but marked “Trend may reverse”. (Illustration from an earlier session.)

1. ATM R2 — the upper resistance reference level.
2. ATM R1 — the nearer resistance reference level.
3. BEP — the index-level break-even line.
4. Mid S&R — the midpoint between support and resistance.
5. ATM S1 — the nearer support reference level.
6. 1st 5min High — high of today’s first 5-minute candle.
7. Today Open — the synthetic future’s opening value today.
8. 1st 5min Close — close of today’s first 5-minute candle.
9. ATM S2 — the deeper support reference level.
10. 1st 5min Low — low of today’s first 5-minute candle.
11. PE sellers panic — a reference level watched for pressure on put sellers. Its mirror is CE sellers panic.
12. S: Straddle — a support reference level from the straddle. R: Straddle is its mirror above.

A nine-line pre-trade checklist then lines up trend, VIX, ATM vs BEP, strikes vs their own open and the sideways clues — green passes, red fails, orange caution, blue information.

3 · BEP — the one line everything is measured against

BEP (break-even premium) is a single premium level, the same for every strike. It is calculated once for the day from the ATM options’ previous-day data, so every strike is judged against the same line.

How you see it on screen: the vs BEP column shows how many points an option is above (+) or below (−) BEP, and in the option chain table the LTP cell is green when at or above BEP and red when below. The common reading: a call above BEP while the put at the same strike is below it means the call side is holding while the put side is fading — that is what the rules look for. When both are on the same side of BEP, the market is range-bound and the screen says Sideways.

4 · The scanner asks three questions about each strike

The rules panel shows each of the nearest strikes as a small card, with a green ✔ or a red ✘ against every question, plus one more tick: whether the option closed above BEP at the last 5-minute candle, and a plain verdict — ALL RULES MET, VERY STRONG, STRONG, POSITIVE, NEAR or NOT MET — so you can see exactly which rule is missing.

5 · Strength colours, “since” times and Sideways

The ATM call above BEP (or above its open) while the ATM put is below it is positive. Add the puts one strike either side below it — strong positive. Add the puts two strikes either side — very strong positive. Each grade is judged two ways — against BEP and against each leg’s own Today Open — and the strike’s own leg must itself be above that line. The rows are coloured light, mid and bright green, and every grade carries a “since 14:57 (9 min)” stamp showing when it first appeared. When the ATM call and put both sit above BEP, or both below it (or both above / below their previous close), the screen says Sideways — premium decay usually dominates, so no new condition is shown.

6 · Reference levels 1 to 4

From the same list of levels, the table shows the four nearest reference levels above the option’s current price, in order — for example “PDC 214.15, Opp H 230.9, PDH 258.62, Uni Res 242.25” (information only, not targets). While an option is still below BEP, BEP itself is shown first, because that is the line it has to cross first.

7 · The option chain table

Below the rule tables is a live option chain: calls on the left, the strike in the middle, puts on the right, for every strike between today’s Nifty low and high (it scrolls). Illustration from an earlier session:

1. PDL / PDH / PDC — the option’s previous-day low, high and close. The cell is green if the live price is at or above that level, red if below.
2. Open and Chg % — today’s opening price, and the change from the previous close in percent.
3. LTP — the live price, coloured against BEP: green at or above, red below.
4. ▴H / C / L badge — the live price is above the opposite option’s previous-day High, Close and/or Low at the same strike. ▴HCL means above all three.
5. Seller ✅ / ❌ — ✅ when the option is trading below its average price for the day, ❌ when it is above.
6. Gold row — the live ATM strike, the one nearest the Nifty spot.

8 · When you are told

1. Only after a 5-minute candle closes. The state is confirmed at 09:30, 09:35, 09:40 … so a flicker inside a candle never alerts.
2. Not in the first 15 minutes, not after 15:10. The screen shows “Observing” until 09:30 and “Alerts paused” from 15:10.
3. Only on a crossing. An alert needs three things together at a 5-minute candle close: a strike’s option closes above BEP after being at or below it on the previous candle; the opposite option at the same strike is below BEP; and the other nearby opposite strikes are below BEP too. Each crossing is one alert, so there are few of them. You get a pop-up with sound on the website and a message on Telegram. There is one extra, one-time alert: at the first candle close from 09:30 (or after a restart), a strike that is already above BEP with the same conditions in place is reported once as “already above BEP”. The only other alert is Sideways, sent once when it starts.
4. Against the trend. If a call alert comes while the synthetic future reads DOWNTREND (or a put alert while it reads UPTREND), it is still sent, but marked “Trend may reverse” so you can see it is against the prevailing trend.

How to read a strike

The rules are written for a call-side view; the put side is the exact mirror. “Positive” here only means the written conditions are met — it is not a prediction.
