The screen

How it is laid out

On a computer the sections sit in a rail down the left: Home and the Signal, then the chart, the option chain, the market map, market pulse, sector scope and momentum spikes, the analysis tabs, news and your record. Your account and the date your access renews are at the foot of the rail. On a phone the rail is a drawer behind the menu button at the top, and Home, Signal, Chart and the option chain sit in a bar along the bottom within reach of a thumb.

The few things that are switches rather than places — index points against option premium, the lot count, whether the tool keeps running when the page is shut — sit beside what they affect instead of behind a menu.

Reading the signal board

Part	What it is telling you
Signal ticket	the call itself — BUY CE, BUY PE, or nothing. OPEN means it is live and tracked; PREVIEW means a direction exists but no ticket was issued. When something is holding the entry, the badge says which: CONFIRMING, COOLDOWN, POSITION OPEN, DAY LIMIT, MARKET OPENING, CLOSING AUCTION or MARKET CLOSED.
Entry / Now	the premium at issue, and the premium now. The rupee figure beside them is that difference across your chosen lots.
Reward : risk	how far the market has room to run, divided by the distance to the stop. Below the floor it never became a ticket at all. It is not what the exit pays — that is in the Risk and reward panel.
T1 / T2 / T3	the three targets, each with how far price has travelled toward it — a check mark and a timestamp once reached.
Stop	with the same progress bar, which is the one you actually want to be watching.
The percentage beside each level	the chance of the index touching it before the 15:30 close (on Bitcoin, within the next 24 hours), from the option chain’s implied volatility and calibrated against past trades. The chances overlap — a trade can touch a target and still hit the stop — so they do not add up to 100 and are not a win rate.
Risk and reward	under the ladder: what the stop costs and what each target makes, in rupees at your lot count after Zerodha’s charges, how many times the risk each target is, and the win rate the trade needs to break even.
Skip cooldown	appears while a cooldown is the only thing holding a ticket. It lifts the wait once; every other check still has to pass, and a ticket issued that way is marked in the trade log.
Holding overnight	in the last hour, an open ticket shows what carrying the position past the close would cost in time decay before the next session — three nights over a weekend — and what buying into the close did in a three-year test. The tool closes its own ticket at the bell.
What if	on an open Nifty, Bank Nifty or Sensex ticket: the premium and the rupee change if the index moves 0.5% either way, if volatility falls 2 points, a day later with nothing moving, and with all three against the position at once. Repriced in full with the same model as the chain rather than estimated from delta and vega — an estimate, not a quote.
Confidence	the dial, with every input that fed it listed underneath. A dash means that input abstained and was ignored rather than counted as neutral.
Market trend	the plain-English label — RANGE-BOUND / CHOPPY, MODERATE DOWNTREND — with the ADX reading and how far price has actually displaced in ATR terms.
Session	everything closed today, in order, with the running total split into booked and open.

Every section, and what it tells you

The Signal is where a trade is decided. The other sections are there to check it against: what the rest of the market is doing, what the options are pricing, and what has happened before. None of them issues a ticket.

Desk

Section	What it shows
Signal	The call itself — BUY CE, BUY PE or no trade — with its levels, the chance of reaching each, what the trade risks and pays, and every reason behind it. Described in full above.
Journal	Your trading journal. A year of trading days as a heatmap coloured by each day’s profit or loss; a month calendar with each day’s P&L and number of trades; and the statistics a journal is read for — win rate, profit factor, average win and loss, best and worst day, deepest drawdown and streaks, for the month or all time. Enter the trades you actually took, beside the tickets the tool issued, and keep a note for each day. Charges on index options are yours or estimated at Zerodha’s rates, so it shows what was kept as well as what was made, and the tool’s own tickets are set against the backtest.

Market

Section	What it shows
Chart	Fifteen-minute candles, or five-minute and daily, with the 20 and 50 EMAs and a VWAP weighted by the index future’s real volume. A live signal’s T1, T2, T3 and stop are drawn as lines. Beside it, today’s range: where price sits between the day’s low and high.
Option chain	The option clock: how open interest changed at each strike within a time window you choose, read from the tool’s own recording of the chain. It is change within the window, not OI added today — positions closing count as much as positions opening. Below it, the chain around the money: last price, bid, ask, spread and open interest for calls and puts.
Market	The index mover: how many index points each member added or took away today, the five pushing hardest and the five dragging most. Then every member with its sector, weight and move.
Market pulse	How many members are up against down, and four screens across them: members breaking a 10-day high or low, a 50-day high or low, trading on volume well above their 20-session average, and sitting nearest their 50-day extreme. On Bitcoin, which has no members, it reads open interest across the live option chain instead.
Screener	Build your own screen over the Nifty, Bank Nifty and Sensex member stocks: RSI, CCI, Williams %R, moving averages (SMA, EMA, WMA), MACD, ADX, ATR, Parabolic SAR, Bollinger Bands and volume, on daily, weekly or monthly candles, compared with a number or with another indicator, now or a set number of bars ago — including a line crossing another. Start from a preset, change it, save your own. It shows which stocks match right now and the values that decided it; it does not say whether trading them makes money.
Sector scope	The market map — every member sized by its weight and coloured by its move, so you can see whether an index is carried by two heavyweights or moving as a whole — and each sector’s weighted move today.
Momentum spikes	The members that moved most over the last five and ten minutes, with their volume against their own average for that time of day. After the close it shows the session’s final minutes, and says so.

Analysis · Indian indices only

Section	What it shows
Volatility	India VIX against the volatility the index actually delivered over 20 sessions. When implied sits above realised, options are expensive for the movement they are getting — that favours the seller and costs the buyer, and it says nothing about direction. Also: where VIX sits in its year, the expected move over a day, a week and to expiry, how often the index really stayed inside its one-day band, and a volatility cone ranking each window against its own year.
Greeks & IV	Implied volatility across the strikes — puts usually dearer than calls, because protection costs more than upside. The chain priced with delta, gamma, theta per day and vega, and where the chain’s gamma is concentrated once weighted by open interest. It shows where that gamma sits, not who holds it: that is not visible from outside the exchange, so it is not claimed.
Levels	Floor pivots — S2, S1, the pivot, R1, R2 — from the previous session’s high, low and close, with ATR(14): the distance the index typically covers in a day, which is what a stop has to survive. And the opening range, with whether price has closed above, below or inside it.
Internals	What the index members are doing underneath the index: how many are above their 20- and 50-day averages, advancing against declining, at new highs or lows, and the advance/decline line over 20 sessions. An index can rise while most of its members fall; a falling line under a steady index means fewer names are carrying it.
Relative strength	The members leading and lagging over the last 20 sessions. In a falling market the leader can still be down — it is only falling least.
Seasonality	The average move by weekday, with how often each day closed up, the spread and the number of sessions behind it. The spread is wider than every average in the table, which is the point: these are tendencies, not rules. And the opening gaps — how often the index opened up, down or flat, and by how much.

Research

Section	What it shows
News	Market headlines, gathered in one place so you can check whether a move has a reason before you trade against it.
Record	A position calculator that turns your capital, your risk per trade, the entry and the stop into a lot count; a recap of the session; your track record — every ticket closed, wins and losses, from the trade file, with nothing left out; and “Why”, every input behind the current reading in full sentences.

On Bitcoin the Chart, Option chain, Market pulse, Momentum spikes, News and Record work the same way; the index-member and India VIX sections do not apply to a market of one instrument, and are hidden rather than shown empty.
