What Should I Do Before Markets Open Today?
A non-advisory playbook — what's worth paying attention to before the 09:15 IST open, broken down by how you actually participate in markets. No buy or sell calls; just process.

"What should I do today?" depends entirely on who's asking. An intraday trader, a long-term SIP investor, and someone who just checks their portfolio monthly have almost nothing in common in terms of what the pre-open period even means to them. Pick the persona closest to you.
Mindset: the open is your highest-volatility, highest-opportunity — and highest-risk — window. Plan the trade before the bell, don't plan it during the first five minutes.
Watch:
- The gap size and direction (see our GIFT NIFTY guide) — a large gap often means wider stops are needed, not tighter.
- Whether global cues and domestic flow signals agree or conflict — conflicting signals usually mean choppier, less trustworthy opening moves.
- Your predefined risk-per-trade limit, set the night before, not adjusted in the heat of the first candle.
Avoid:
Chasing the very first move in the opening minute — the first 5–15 minutes are often the most volatile and least reliable part of the session.
Mindset: the open matters less minute-to-minute and more as confirmation (or contradiction) of your existing thesis on a position.
Watch:
- Whether the broader tone (global markets, FII/DII flows) still supports the setup you entered on, or whether something has shifted.
- Sector-specific news that might matter more to your positions than the index-level open.
Avoid:
Exiting a multi-day thesis because of one noisy opening print that doesn't actually change the underlying setup.
Mindset: for a multi-year holding, a single morning's opening bias is close to irrelevant to the outcome. This is a "stay informed, don't react" zone.
Watch:
- Company- or sector-specific news that could actually change your investment thesis, not daily index noise.
- Whether a large market move (in either direction) creates a genuine rebalancing opportunity relative to your target allocation.
Avoid:
Checking your portfolio every morning based on the opening bias — for long-horizon money, this usually adds anxiety without adding useful information.
Mindset: your investment amount and date are already automated — that's the entire point of a SIP. The opening bias on any given day should have zero influence on it.
Watch:
- Nothing daily, by design — that's the discipline a SIP is meant to enforce.
- Once a year: whether your SIP amount still matches your income and goals (see our 1-page money plan guide).
Avoid:
Pausing or skipping a SIP instalment because the opening bias looked negative that morning — this is one of the most common ways investors accidentally sabotage the averaging benefit a SIP is designed to give them.
Mistakes worth avoiding, regardless of persona
- Treating a single morning's directional read as a prediction of the full day's, week's, or month's performance.
- Making a large financial decision based on one data point instead of your own plan and time horizon.
- Confusing "sentiment context" with "advice to act" — see our methodology page for exactly what the opening-bias score does and doesn't claim to tell you.
