Impact cost: jo dikha tha aur jo mila.
Doosre naam: impact cost, slippage, execution cost, spread cost, market impact.
Ise kaise padhein
Screen par jo daam dikhta hai woh aakhri trade ka hai. Naya order us daam par apne aap nahi bhar jaata — use order book mein maujood doosri taraf se milna padta hai.
Chhota order sabse upar wale level par bhar sakta hai. Bada order us level ko khatam karke agle level tak jaata hai, phir agle tak. Har agla level thoda kam achha hota hai, aur wahi antar impact cost hai.
Yeh kya nahi batata
Impact cost koi rate nahi hai jo kahin publish hoti ho. Exchange apna impact-cost aankda deta hai, lekin woh ek maani hui standard size par hota hai — usse badi size par woh kam bata raha hoga.
Aur yeh sthir bhi nahi hai. Din ke samay, khabar, aur bazaar ki halchal ke saath badalta rehta hai — aur aksar tab sabse zyada hota hai jab nikalna sabse zaroori lagta hai.
Experiment mein dekho
Bid/Ask and Slippage — Example order ko bid aur ask levels se guzaro. Spread, hisso mein fill aur slippage dekho, aur samjho ki fill aakhri trade ke daam se alag kyun ho sakta hai.
Jude hue concepts
Market order aur limit order: har ek kuch deta hai, kuch nahi.
Market order execution ko priority deta hai, price ki guarantee nahi. Limit order price tay karta hai, fill ki guarantee nahi. Dono ka trade-off.
