Support aur Resistance — Price Memory ka Vigyan

Markets human psychology se driven hain. Jab price ek particular level se bounce karta hai multiple times, traders us level pe buy karna seekh jaate hain. Yeh self-fulfilling prophecy ban jaati hai. Zyada log support pe buy karte hain, zyada effective woh support ban jaata hai.

Round numbers psychologically significant hote hain. NIFTY 20,000 ya 25,000 ya Sensex 70,000 yeh levels market mein zyada attention attract karte hain. Options traders in levels pe options write karte hain. Institutional investors yahan pe orders place karte hain. Yeh sab collective action in levels ko important bana deta hai.

Previous swing highs aur lows important support resistance levels hote hain. Agar NIFTY pichle month 22,500 pe resist kiya aur neeche aa gaya, phir wapas 22,500 ke paas aaye toh market ki memory wahan hai. Buyers jo pehle 22,500 pe buy karke stuck the woh break-even pe sell karna chahenge.

Ek important concept hai support resistance flip. Jab price ek strong support level ke neeche break karta hai, woh support level ab resistance ban jaata hai. Aur agar price ek resistance ke upar break karta hai, woh resistance level ab support ban jaata hai.

Why does this happen? Maan lo NIFTY 22,000 pe support tha. Kai baar bounce kiya. Phir ek baar 22,000 ke neeche gaya. Jo investors 22,000 pe long the, woh ab loss mein hain. Jab NIFTY wapas 22,000 ke paas aata hai, woh break-even pe exit karna chahte hain. Yahi selling pressure 22,000 ko ab resistance banata hai.

Ise 'polarity flip' ya 'support becomes resistance' principle kehte hain. Experienced traders is concept ko extensively use karte hain entries aur exits plan karne ke liye.

Subjective support resistance drawing se aage badhke quantitative approach lena better hai. Volume Profile ek powerful tool hai. Yeh dikhata hai ki kis price level pe sabse zyada volume traded hua. High volume nodes generally strong support resistance areas hote hain kyunki wahan pe bahut sare positions hain.

Point of Control (POC) woh price hai jahan maximum volume trade hua. POC ke aas paas price often return karta hai kyunki itni many market participants wahan pe involved hain. Low Volume Nodes (LVN) woh areas hain jahan volume kam tha. Price generally rapidly move karta hai through LVN kyunki wahan pe koi significant interest nahi hai.

NSE ke options chain mein maximum Open Interest wale strikes generally strong support resistance act karte hain especially near expiry. Yeh pin risk create karta hai near those levels.
