4.4.3· Stock-Market › When to Trade — Timing & Sessions
Opening range kyun matter karta hai?
Yeh kyun exist karta hai (first principles):
- Raat bhar news aati hai (earnings, global markets, economic data). Traders exchange band rehne par kuch nahi kar sakte, isliye buy aur sell orders accumulate hote hain.
- Bell bajte hi (NSE ke liye 9:15 AM IST), yeh orders ek rush mein execute hote hain → aam taur par din ka sabse zyada volume aur volatility yaheen hoti hai.
- Activity ka yeh burst jaldi ek fair price band "discover" kar leta hai. Uss band ke extremes (high/low) woh jagah hai jahan buyers aur sellers ne sabse zyada fiercely disagree kiya.
- Woh extremes memory levels hain: traders unhe yaad rakhte hain, unke aaspaas orders lagate hain → yeh baad mein self-fulfilling support/resistance ban jaate hain.
Key pieces kya hain?
Iska use kaise karte hain? (ek simple ORB strategy)
ORB = Opening Range Breakout.
- Pehle 15 (ya 30) min se OR High aur OR Low mark karo.
- Wait karo — range ke andar trade mat karo (woh noisy chop hai).
- Agar price OR High ke upar close kare → potential long (buyers jeet gaye).
- Agar price OR Low ke neeche close kare → potential short (sellers jeet gaye).
- Stop-loss = range ka doosra side (ya mid-point).
- Target = measured move (upar wala formula).
Worked Examples
Recall Feynman: ek 12-saal ke bachche ko explain karo
Socho school ka gate khulta hai aur sab ek saath andar daudh ke aate hain — dhakka-mukki, chillana. Pehle kuch minutes mein kuch bachche door-left wall tak daude, kuch door-right wall tak. Woh dono walls ab din ke liye playground ki "edges" hain. Agar baad mein koi left wall ke aage daude, toh sabko pata chal jaata hai kuch bada ho raha hai aur sab follow karte hain. Pehle 15–30 minutes sirf woh dono walls paint karte hain. Walls paint hone ka wait karo, phir dekho kaun cross karne ki himmat karta hai.
Flashcards
Opening range (OR) kya hota hai?
Market khulne ke baad pehle fixed window (15 ya 30 min) mein price ka high aur low.
Pehle 15–30 min sabse zyada volatile kyun hote hain?
Raat bhar ke orders (news, global markets se) accumulate hote hain aur ek saath execute hote hain, jisse din ka sabse zyada volume aur price swings aate hain.
OR width ka formula?
OR Width = OR High − OR Low.
Range ko percentage mein normalize kyun karte hain?
Absolute rupaye scale reflect nahi karte; % se alag-alag prices wale stocks ki volatility compare kar sakte hain.
Opening Range Breakout (ORB) trade kya hota hai?
OR form hone ka wait karo, phir OR High ke upar confirmed close par long lo ya OR Low ke neeche short lo.
Measured-move upside target ka formula?
OR High + (OR High − OR Low).
Pehle minute mein trade kyun NAHI karna chahiye?
Yeh sabse random/whipsaw moment hota hai jisme frequent false breakouts hote hain; range form aur confirm hone ka wait karo.
ORB long par stop kahan lagaate hain?
OR Low par (ya range mid-point par) — range mein wapas aana break ko invalidate karta hai.
Bahut WIDE opening range kharab signal kyun ho sakta hai?
Stop bahut door hota hai → poor risk-reward, aur move ka bada hissa already khatam ho chuka ho sakta hai.
NSE (India) equity market open time?
