A complete guide to reading signals, interpreting the option chain, selecting strikes, and managing trade risk — all in one screen.
Open the Tool →The three inputs at the top control everything on the page.
Type any NSE stock or index: NIFTY, BANKNIFTY, JSWSTEEL, RELIANCE, ITC, etc. The expiry list updates automatically within 600 ms as you type.
The dropdown shows upcoming expiries sorted nearest-first (weekly for indices, monthly for stocks). Choose the contract you want to trade.
CE = you expect price to rise (buy a Call). PE = you expect price to fall (buy a Put). This controls which signals are evaluated and which strike is suggested.
Fetches live chain data, computes all 11 signals, selects the optimal strike, and builds the risk plan — all in one shot.
Refresh Expiries button forces a reload of the expiry list. Use it after a monthly expiry has passed and the dropdown hasn't updated.
Appears on the right side after Analyze. Shows the pre-market and live environment for the symbol.
| Field | What it means |
|---|---|
| Spot | Current market price of the underlying (from yfinance, refreshed on each Analyze). |
| India VIX | Market fear gauge. Below 14 = calm (green), 14–20 = normal (yellow), 20–30 = elevated (orange), above 30 = extreme (red). |
| Prev Close | Yesterday's closing price. Used to determine gap direction. |
| PDH / PDL | Previous Day High / Low — key intraday reference levels. |
| Weekly High / Low | Range of the last 5 trading sessions — shows the broader swing context. |
| Gap Est. | Today's open vs yesterday's close. Positive = gap up, negative = gap down. |
| Bias | BULLISH if spot > prev close by 0.5%, BEARISH if spot < prev close by 0.5%, otherwise NEUTRAL. |
The circular gauge on the left is the core output. It sums 11 weighted signals into a single number. The higher the score, the stronger the conviction for entering a trade in the chosen direction.
OI Change signals show "unchanged" for the first 30–55 minutes after the engine starts. This is normal — the engine compares current OI against a snapshot taken 30–55 min ago. Allow the engine to run for at least one hour before relying on OI change signals.
Each signal is evaluated independently. The score next to each shows earned / max points.
| Signal | Max | Pass condition | Why it matters |
|---|---|---|---|
| VIX Normal | 1 | VIX < 20 | High VIX means options are expensive and moves are erratic — bad for buying. |
| IV Not Spiked | 2 | VIX < 25 | Implied volatility spike inflates premiums, reducing the reward-to-risk ratio. |
| PCR Aligned | 2 | CE trade: PCR > 1.3 (BULLISH) = 2pts. NEUTRAL = 1pt. Opposite = 0pts. |
Put-Call Ratio reflects aggregate market positioning. High PCR = more puts written = bullish. |
| OI Wall Clear | 2 | CE: Resistance > Spot × 1.01. PE: Support < Spot × 0.99. |
If the resistance wall (highest CE OI strike) is right at spot, call writers will defend it — price unlikely to break through. |
| OI Change Confirms | 2 | CE: Target strike OI signal is long_buildup or short_covering. PE: Same for put side. |
Fresh long buildup at the target strike means real money is betting in your direction. |
| EMA Trend | 2 | CE: EMA9 > EMA21 AND price > EMA9. PE: EMA9 < EMA21 AND price < EMA9. |
EMA crossover on intraday (5-min) candles confirms the trend direction you're trading. |
| VWAP Position | 1 | CE: Price > VWAP. PE: Price < VWAP. |
VWAP is the institutional average price for the day. Being on the right side shows institutional flow support. |
| Volume Confirmed | 2 | Today's volume ≥ 80% of average volume. | Low volume moves are unreliable. Volume confirmation ensures the move has conviction. |
| RSI Aligned | 1 | CE: RSI between 45–70. PE: RSI between 30–55. |
RSI in overbought/oversold extremes reduces reward potential. Ideal RSI is in the momentum zone, not the exhaustion zone. |
| Time Window | 1 | Current time is between 9:15 AM and 2:00 PM IST. | The first 15 minutes and last 90 minutes of the session are erratic. Best entries are 9:15 AM–2:00 PM. |
| No News Risk | 1 | Current time is before 2:30 PM IST. | Results, announcements, and event risks increase after 2:30 PM. Avoids late-session surprises. |
The chain table at the bottom shows live data for all strikes. The layout is symmetric — Calls on the left, Puts on the right, Strike in the center.
| Column | What it shows |
|---|---|
| OI Signal | 4-quadrant OI change classification for this strike (see Section 6). Updates after 30–55 min of engine runtime. |
| OI | Open Interest — total outstanding contracts. Yellow highlight = top 20% OI strike = wall/resistance/support level. Bar width shows OI relative to the max on that side. |
| LTP | Last Traded Price of the option contract. |
| IV% | Implied Volatility in percent. High IV = expensive option premium. |
| STRIKE | The option strike price. ▶ marks the ATM (At-The-Money) strike closest to spot. MP badge marks the Max Pain strike. |
| — (dash) | No data available — deep OTM strikes with no trading activity. This is normal. |
The strike with the highest CE OI is the resistance wall — call writers are defending that level. The strike with the highest PE OI is the support wall. These are visible in the Max Pain & PCR tab.
The engine saves an OI snapshot every time you Analyze. After 30–55 minutes it compares current OI and LTP against the old snapshot to classify each strike into one of four patterns.
| Signal | Price | OI | What's happening | Implication |
|---|---|---|---|---|
| long buildup | ↑ Rising | ↑ Rising | Fresh long positions being added | Bullish — confirm CE trade |
| short buildup | ↓ Falling | ↑ Rising | Fresh short positions being added | Bearish — confirm PE trade |
| short covering | ↑ Rising | ↓ Falling | Shorts are exiting (buying back) | Bullish — supports CE trade |
| long unwinding | ↓ Falling | ↓ Falling | Longs are exiting (selling) | Bearish — supports PE trade |
| unchanged | No prior snapshot yet | Wait 30–55 min after engine start | ||
After Analyze, the tool automatically selects the best CE or PE strike based on delta, spread, OI, and distance from spot. The selected strike box shows:
| Field | What it means |
|---|---|
| LTP | Current premium you pay to buy this option. |
| Delta | How much the option price moves for every ₹1 move in the underlying. Closer to 0.5 = ATM. Above 0.7 = deep ITM. |
| IV | Implied Volatility of this specific strike. |
| Bid / Ask | Best buy and sell price in the order book. |
| Spread | Bid-Ask spread as % of LTP. Below 3% is good liquidity. Above 8% means wide spread — hard to enter and exit cleanly. |
Spread above 5–8% is a warning sign. You lose that percentage immediately on entry. Prefer liquid strikes (usually within 2–3% of spot) where spread is tight.
Automatically computed from the selected strike's LTP. Shows the full trade plan with defined risk and reward.
| Field | How it's calculated |
|---|---|
| Entry LTP | The selected strike's current premium. |
| Lots × Size | Number of lots × lot size = total quantity traded. |
| Total Premium | Entry LTP × total quantity = capital deployed. |
| Stop Price | Entry LTP × 0.5 (50% of premium — standard options stop). |
| Target 1 | Entry LTP × 1.5 (1.5× risk-reward on first target). |
| Target 2 | Entry LTP × 2.0 (2× risk-reward on second target). |
| Max Loss | (Entry − Stop) × qty = worst-case premium loss. |
| Profit @ T1 / T2 | Potential P&L at each target level. |
Rule of thumb: Never risk more than 1–2% of your total capital on a single option trade. Use the Total Premium figure to check this before placing the order.
Found in the Trade Monitor tab at the top of the chain section. After you enter a trade, input your levels to get a live action recommendation.
Enter the price at which you bought the option, and the current market price of that option.
Pre-filled from the risk calculator — you can override them. Stop Price is where you exit to cut losses. Targets are your profit-booking levels.
Set the correct lot size for your symbol. Mark T1 Hit = Yes once you've booked partial profits at Target 1 — the monitor will adjust trailing logic accordingly.
Returns an action: HOLD, EXIT_STOP, BOOK_T1, BOOK_T2, or TRAIL_STOP — along with current P&L and the reason.
Here is the complete process from market open to trade execution using this tool.
| Check | Green light | Red light |
|---|---|---|
| Signal Score | ≥ 10 (MODERATE or STRONG) | ≤ 5 (SKIP) |
| VIX | Below 20 | Above 25 — avoid buying options |
| OI Wall | Resistance/Support at least 1% away from spot | Wall right at spot — price likely to get pinned |
| Bid-Ask Spread | Below 3% of LTP | Above 8% — illiquid strike, avoid |
| Time | 9:30 AM – 1:30 PM IST | After 2:30 PM — event & expiry risk |
| EMA | Trend aligned with direction on 5-min chart | EMA9 and EMA21 flat or crossing against you |
Best results come when Score ≥ 12, VIX < 18, EMA trend aligns, and the OI wall is at least 2% away. These conditions align roughly 2–4 times per week for liquid symbols like NIFTY, BANKNIFTY, and large-cap stocks.
