Introduction As markets gear up for October 13’s opening, traders will lean heavily on cues from global indices, derivative flows, and sector rotation. A few crucial levels and structural cues will likely influence intraday bias and short swing opportunities. In this Trade Setup for 13 October 2025, dhwani patel, SEBI registered research analyst and founder of Finversify, presents 10 trade-relevant setups to monitor before the bell. Use these as guides—contextual inputs—not rigid prescriptions. Setup 1 — Nifty 50: structural zones to respect From pre-market data: resistance near 25,400–25,450, and support around 25,200–25,100 were noted as key zones. These ranges frame any early bias. Why it matters:These levels act as magnets or rejection zones. If Nifty stays inside the band, expect choppy trade; a directional breakout (with confirmation) should dictate flow. How to frame it: Setup 2 — Bank Nifty: pivot and triggers Bank Nifty’s pivot range for the session was identified with resistance near 57,200–57,400 and support around 56,600–56,400. A failure to breach resistance could invite short-term reversals. Why it’s critical:Banking index momentum often leads and confirms the broader indices. When Bank Nifty is strong, it lifts financials and related sectors. Trader’s lens: Setup 3 — Call Open Interest Clusters Key call strikes with heavy open interest include 26,000, 25,800, and 25,600. These strike levels may serve as resistance traps if price approaches them. Interpretation:Clusters of call OI often signal where large participants expect upside to slow. If price nears these points, observe volume / OI movement to test strength. For options players: Setup 4 — Put Open Interest & Support Floor On the put side, strikes like 25,200, 25,000, 24,800 displayed the largest concentrations of OI. These make for reference floors—especially if Nifty dips. Why useful:Strong put OI zones often act as soft supports or magnet zones. A breach below them usually leads to quick downside acceleration. Use advice: Setup 5 — Bank Nifty Options: mapping financial bias In Bank Nifty’s options chain, the highest call interest lay near 57,500, followed by 57,000; on the put side, strikes like 56,000 and 55,500 registered heavy OI. What this suggests:There is an expectation that Bank Nifty may struggle beyond 57,500; support is likely clustered nearer to 56,000. For index futures strategies, monitoring how Bank Nifty behaves relative to these option levels gives early cues on where traders are placing hedges or bets. Setup 6 — Put-Call Ratio & Trader Sentiment An elevated PCR (above its short-term average) suggests that more participants are buying protection or expecting downside. Conversely, a falling PCR indicates more optimistic sentiment. Given Mercury’s projection in the pre-market report, shifts in PCR around intraday highs/lows will offer confirmation or warning signs of trend exhaustion. How to integrate: Setup 7 — India VIX: volatility context Pre-market data showed India VIX in a moderate range, indicating market participants see some room for volatility. A sudden spike could trigger option-based rebalancing. Why it’s key:VIX jumps often precede intraday reversals or trend changes — especially when markets are extended. Tactical note:If VIX remains steady, trades with tight risk/reward can work well; if it steps up, use smaller sizing or protective hedges. Setup 8 — Flow Profiles: long builds, unwinds, shorts The pre-session report flagged notable long build-ups in many stocks, some short covering, and pockets of unwinding. Tracking which names are seeing aggressive positioning can highlight where institutional interest lies. Why it matters:These flow signals often lead price — especially when they align with technical patterns. Usage idea for swing traders: Setup 9 — Delivery Data & F&O Bans High delivery percentages in certain stocks indicate actual accumulation rather than intraday noise. Note also which stocks are in the F&O ban list — such names behave erratically because new positions are limited. Why important:If a name is seeing high delivery + participation, it’s more likely to have sustainable momentum. Banned names, conversely, pose added structural risk. Practical use: Setup 10 — Macro Cues & Global Markets Global markets, US yields, crude trends, and currency moves continue to set the backdrop. Pre-market summary indicated that US futures were marginally down, crude oil prices were firm, and Asian peers opened with mixed cues. Why it’s relevant:Domestic flows (especially FII) often depend on global risk appetite. A shift in US or commodity cues can cascade quickly into Indian markets. How to stay prepared: Building a Practical Checklist from These Setups To help convert these 10 insights into structured approach, here’s a sample checklist (educational — not trade instructions): This framework aligns with index futures trading strategies India and meshes well with swing trade principles.

Introduction — quick read before the bell Markets open and close on many forces: global cues, domestic flows, sector rotation, derivative positioning and investor psychology. For the October 10 session, several technical and flow-based signals deserve attention because they set the intraday and near-term bias for participants. This write-up by dhwani patel distills 10 pragmatic market setups you should watch before the opening bell — explained so you can apply them whether you trade intraday, use index futures, or hold short swing positions. Where relevant, I reference pre-market data and derivative positioning published by market trackers to make these setups concrete and repeatable. Keep in mind this is analysis to help preparation, not a buy/sell call. All factual market data referenced below is taken from the pre-market market summary published for October 10. Setup 1 — Nifty: primary battle band to watch (the macro pivot) What the market said (key levels): If the Nifty manages to reclaim and sustain above 25,200, the immediate targets to watch were 25,350–25,450, provided the index continues to defend 25,000–24,900 as support. These levels were highlighted in the pre-market briefing as the main reference band for the session. Why it matters: The Nifty band is the structural frame for both index trades and stock selection. When Nifty is inside this band, expect range-bound rotation; a clean breakout or breakdown usually signals a higher-probability directional phase. How to use it (framework, not a trade call): Setup 2 — Bank Nifty: watching the financial engine Pre-market read: Bank Nifty’s pivot and resistance levels were noted with pivot-based resistance around 56,276 / 56,381 / 56,550 and pivot supports around 55,938 / 55,834 / 55,665; Fibonacci resistance extended higher near 56,758 / 57,628. The daily chart shows bullish bias but profit booking pockets exist. Why it matters: Bank Nifty tends to lead or confirm broad market direction. A strong Bank Nifty often pulls other cyclical and financial names higher; a weakness there amplifies market-wide selling. How traders may frame it: Setup 3 — Option chain: where the crowd’s tape is written (Calls) What the data shows: On the call side, the weekly maxima were concentrated at strikes like 26,000 (1.34 crore contracts), followed by 25,500 (1.03 crore) and 25,200 (98.31 lakh). Heavy call writing was observed at strikes such as 25,400, 25,600 and 25,550 — which can show where short-term sellers are positioning resistance. Why it matters: Call open interest clusters and addition/ unwinding are visual cues for where professional traders expect or cap upside. For options-sensitive trades, these strikes often become reference points during the session. Strategy lens (education, not advice): Setup 4 — Option chain: where support lies (Puts) What the data shows: On the put side, the 25,000 strike held the maximum put open interest (≈1.37 crore contracts), followed by strikes like 25,100 and 24,500. This indicates a strong put-support zone near 25,000 — a psychological and technical base the market watched. Why it matters: Large put concentrations can act as a magnet for price (support) but may also represent sellers hedging. A breach of such a band is often followed by accelerated moves as stop-losses and option positions react. Trader’s approach: Setup 5 — Bank Nifty options: a separate map for financial trades Snapshot: Bank Nifty’s OI peaks were at 57,000 (max Call OI) followed by 58,000 and 56,000; maximum Put OI clustered near 55,000. Notably, call writing concentrated at 56,500 and 57,500, pointing to where resistance may be held in the short term. How to interpret: For traders focused on financials, Bank Nifty options tell a parallel story — where participants expect resistance/support in the banking index. Because banks have outsized weight, these signals can spill into Nifty direction and liquidity. Tactical note: those using index futures trading strategies India should watch Bank Nifty OI structure for early signs of sector stress or strength. Setup 6 — Put-Call Ratio & skew: the sentiment thermometer What it indicates: Put-Call Ratio movements give a sense of directional sentiment. A rising PCR (above historical averages) points to defensive sentiment; the pre-market noted the market’s PCR dynamics and what shifts might imply for intraday bias. How to use: Setup 7 — India VIX: complacency vs opportunity Current reading: India VIX had dropped to the low-teens (~10.12 as reported), remaining below short-term moving averages — this low volatility zone suggests a comfort window for bulls but warns of potential sudden spikes. Why it’s important: Low VIX means option premiums are cheaper — good for defined risk long strategies but risky if volatility spikes unexpectedly. Conversely, VIX upticks often accompany disorderly moves rather than orderly corrections. How to act on it (education): Setup 8 — Flow & positioning: long/short builds and the hidden tape Pre-market reads: The report highlighted a long build-up in 104 stocks, some long unwinding in a few counters, short build-ups in others, and extensive short-covering in many names — essentially a mixed internals snapshot that traders must parse. Why flows matter: These on-chain OI moves are signs of conviction — long builds with rising prices imply accumulation; long unwinding suggests profit booking. The balance across hundreds of stocks offers context to whether the market is broadening or narrowing. Actionable lens: Setup 9 — Delivery & F&O ban list: structural clues for allocation What the report noted: There were lists of high-delivery trades (stocks showing genuine investor accumulation) and F&O ban status (few changes; RBL Bank retained on the banned list at the time). Stocks under F&O restrictions can behave erratically as fresh positions are limited. Why this is useful: Delivery-heavy moves indicate long-term buying, which is a stronger signal than intraday buzz. F&O bans and their composition tell you which names to avoid if you need flexible sizing. How to integrate into your plan: Setup 10 — Macro and global cues: don’t trade in a vacuum Context: Globally, bond yields, crude prices and US market sessions can pivot flows into India quickly. For October 10, watching global risk indicators remains critical — they often drive
