Overnight, news breaks (earnings, global markets, economic data). Traders can't act on the exchange while it's closed, so buy and sell orders accumulate.
At the bell (9:15 AM IST for NSE), these orders execute in a rush → highest volume and volatility of the day usually happens here.
This burst of activity quickly "discovers" a fair price band. The extremes of that band (high/low) are where buyers and sellers most fiercely disagreed.
Those extremes are memory levels: traders remember them, place orders around them → they become self-fulfilling support/resistance later.
Imagine the school gate opens and everyone rushes in at once — pushing, shouting. In those first few minutes some kids run to the far-left wall, some to the far-right wall. Those two walls are now the "edges" of the playground for the day. If someone later runs past the left wall, everyone knows something big is happening and they all follow. The first 15–30 minutes just paints those two walls. Wait for the walls to be painted, then watch who dares cross.
Dekho, jab market subah 9:15 baje khulta hai, tab raat bhar ka saara news, global market ka mood, sab ek saath orders ke roop mein market mein aa jaata hai. Isliye pehle 15–30 minute mein sabse zyada volume aur sabse zyada volatility hoti hai. Is time mein jo sabse upar (OR High) aur sabse neeche (OR Low) price banti hai, usko hum opening range kehte hain. Ye do levels din bhar ke liye ek tarah ke "diwaar" ban jaate hain — support aur resistance.
Ab strategy simple hai: range banne do, andar mat trade karo (andar sirf noise hota hai). Jab price OR High ke upar close kare to buyers jeet gaye — long socho. Jab OR Low ke neeche jaaye to sellers jeet gaye — short socho. Isko Opening Range Breakout (ORB) kehte hain. Stop-loss range ke opposite side pe rakho, aur target ke liye ek "measured move" use karo — matlab range ki width ko breakout point pe add ya subtract kar do.
Sabse badi galti jo naye traders karte hain: pehle candle pe hi jump kar jaana. Wo moment sabse random hota hai, false breakout bahut aate hain — stop hit hoke phir reverse. Isliye B.A.K.E. yaad rakho: Boundaries banne do, Avoid inside, Keep watching, Enter on break. Range ko 30 minute "bake" hone do, tabhi khao. Aur haan, width ko percentage mein dekho taaki alag-alag price wale stocks compare kar sako — ₹10 ka range 100 rupee ke stock pe bada hai, 1000 rupee ke stock pe chhota.
