use of trailing stop

Mein ap se agree nahi karta, 2000 pips to bohot ziyada hain and itna target rakhna sahi nahi ha. Trailing stop ka matlab ye hay kay apni trade ko secure rakhna, jesay jesay market ap kay trade kay haq mein move karti ha, wesay wesay apka tradiling stop bhi move karta ha ta'k jab market reverse ho to ap kay trailing stop par trade maximum profit mein close ho jaye. For example, ap na Eur/Usd ko 1.2200 par buy kiya aur 30 pips trailing stop lagaya aur initial stop loss 1.2150 set kiya, to jab price 1.2230 par aay gi to apka stop loss bhi 1.2250 se 1.2180 ho jaye ga aur is tarhan jesay jesay price agay jaye gi, trailing stop bhi modify hota rahay ga.
