पोजीशन साइजिंग क्या है?
पोजीशन साइजिंग वह पद्धति है जिसका उपयोग यह निर्धारित करने के लिए किया जाता है कि किसी विशेष व्यापार में कितनी बड़ी पोजीशन लेनी है। यह जोखिम प्रबंधन का एक महत्वपूर्ण पहलू है जो व्यापारियों को अपनी पूंजी की सुरक्षा करने में मदद करता है जबकि संभावित रिटर्न को अधिकतम करता है।
प्रमुख अवधारणाएँ
गणना विधियाँ
- पूंजी का प्रतिशत
- निश्चित जोखिम राशि
- अस्थिरता आधारित साइजिंग
- केली मानदंड
- जोखिम/इनाम अनुपात
जोखिम विचार
- खाता आकार
- बाजार की अस्थिरता
- ट्रेडिंग लीवरेज
- स्टॉप लॉस दूरी
- बाजार की तरलता
सामान्य दृष्टिकोण
निश्चित प्रतिशत जोखिम
- प्रति व्यापार 1-2% जोखिम
- खाता संतुलन आधारित
- अस्थिरता के लिए समायोजित
- स्थिरता बनाए रखता है
पोजीशन स्केलिंग
- पोजीशनों में पिरामिडिंग
- इन/आउट स्केलिंग
- कई लक्ष्य
- जोखिम समायोजन

आसान शब्दों में
Position Sizing "kitna risk lo" ka formula hai — sabse important decision in trading, more important than entry timing! Simple rule: "Never risk more than 1-2% of your capital per trade"। Example: ₹10 lakh account → max ₹10K-₹20K risk per trade। Position size = risk amount ÷ (entry - stop-loss distance)। Small position = survive losing streaks, big position = one bad trade wipes account। Professional traders spend 80% of effort on position sizing, 20% on market analysis।
वास्तविक उदाहरण
Two traders, both correct on market direction, different position sizes:
Trader A (Professional Sizing):
- Account: ₹10 lakh, Risk per trade: 1% (₹10K)
- BTC long @ $67,000, Stop Loss @ $65,000 (2.93% distance)
- Position size: ₹10K ÷ 2.93% = ₹3.41 lakh (~5.1 BTC worth)
- Leverage needed: ~3.4x (comfortable)
- Result: BTC drops to $64,500 first → stopped out, loss = ₹10K (1%)
- Next trade: still has ₹9.9 lakh capital, continues trading
Trader B (Aggressive Sizing):
- Same account: ₹10 lakh, Risk: 25% (₹2.5 lakh!) per trade
- Same setup, same stop loss
- Position size: ₹85 lakh (~127 BTC worth)
- Leverage needed: 85x (!!!)
- Result: Same drop to $64,500 → loss = ₹2.5 lakh (25%)
- Next trade: only ₹7.5 lakh left, psychologically damaged
- 3 more losses at this sizing → account nearly wiped
Same analysis, same direction, vastly different outcomes — position sizing IS the edge।
सामान्य प्रश्न
प्रश्श्च: Kelly Criterion kya hai? उत्तर: Mathematical formula for optimal position size based on win rate and reward:risk ratio। Formula: f* = (bp - q) / b where b=net odds, p=win prob, q=loss prob। Kelly suggests aggressive sizes — most traders use "half-Kelly" for safety। Kingfisher has built-in Kelly calculator।
प्रश्श्च: Volatility-adjusted sizing kya hai? उत्तर: Smaller positions in volatile markets (wider stops needed for same confidence), larger positions in calm markets। ATR (Average True Range) based sizing: position inversely proportional to volatility — adapts automatically to market conditions।
प्रश्श्च: Correlated positions kaise handle karein? उत्तर: If holding long BTC AND long ETH, they're highly correlated (~0.85) — combined risk much higher than individual risks suggest। Either: reduce each position size by correlation factor, or treat portfolio as single correlated bet। Diversification across uncorrelated assets allows larger individual sizes safely।
प्रश्श्च: Kingfisher position sizing tools? उत्तर: हाँ — auto position size calculator (input account %, stop distance → get exact size), portfolio heat meter (total exposure across all positions), correlation-aware risk dashboard, drawdown simulator available हैं।
प्रश्श्च: "Risk of ruin" calculate kaise karte hain? उत्तर: Probability of losing entire account given win rate, average win/loss, and position size। Even 55% win rate with 20% risk per trade = 99% ruin probability within 100 trades! With 1% risk = near-zero ruin probability mathematically। This is why pros size small।
