Gaussian Model in Forex Trading: Understanding Price Movements
Assalam o Alaikum Dear Friends, Forex trading mein Gaussian model ka matlab yeh hota hai ke hum currency prices ki movements ko ek normal distribution ya Gaussian distribution ke zariye samajhne ki koshish karte hain. Iss model mein, price changes ko random variables samjha jata hai, jo ek bell-shaped curve ko follow karte hain, jise normal distribution kaha jata hai. Lekin, forex market ki price movements kaafi unpredictable hoti hain, aur kabhi kabar aise extreme fluctuations bhi dikhate hain jo Gaussian model ke assumptions ke mutabiq nahi hoti.
1. Price Movements as Random Variables
Forex mein, Gaussian model ke mutabiq price changes ko randomly distribute hone wala mana jata hai. Iska matlab yeh hai ke currency pair ka price movement ek average value ke aas paas hota hai, aur iska spread (volatility) standard deviation ke zariye measure kiya jata hai.
2. Expected Return and Volatility
Mean (µ): Yeh average return ya price movement ka indicator hota hai, jo aksar zero ke qareeb hota hai.
Standard Deviation (σ): Isse price movement ki volatility ka andaza lagaya jata hai. Zyada standard deviation ka matlab hai ke prices zyada range mein move kar rahe hain, yani market mein zyada volatility hai.
3. Risk Management
Gaussian model traders ko madad deta hai ke woh yeh andaza laga sakein ke price movements kis range mein rehne ke chances hain. Jaise:
68% chances hain ke price 1 standard deviation ke andar hoga.
95% chances hain ke price 2 standard deviations ke andar hoga. Isse traders ko risk samajhne aur stop-loss ya take-profit levels set karne mein madad milti hai.
4. Value at Risk (VaR)
VaR ek ahem statistical tool hai jo kisi portfolio mein maximum loss ka andaza lagata hai ek specific time period ke liye. Gaussian model ke zariye, hum yeh jaanne ki koshish karte hain ke kisi currency position par kitna risk hai agar price normal distribution ko follow kar raha ho.
5. Limitations in Forex Trading
Forex markets hamesha Gaussian model ko follow nahi karte. Forex mein aksar extreme price movements hoti hain jo Gaussian distribution se zyada frequently aati hain. Is wajah se advanced models, jaise GARCH ya Jump Diffusion Models ka bhi istemal hota hai taake zyada accurate predictions ki jaa sakein.
6. Option Pricing
Gaussian model se hi kuch models, jaise Black-Scholes, tayar kiye gaye jo options pricing ke liye istemal hote hain. Yeh models yeh assume karte hain ke underlying currency normal distribution follow kar rahi hai.
Summary
Gaussian model forex market ke price movements aur risk ko samajhne ke liye ek useful tool hai. Lekin, yeh har waqt market ke unpredictable nature aur volatility ko accurately capture nahi karta.
