Dear aap spread ko aik qisam ko fee bhi keh sakte ho jo k broker aap se charg kr rha hota hai
Ham jiss bhi broker k plateform pe trading kr rhe hote hain hamen usse kch na kch fee pay krna parti hai
Isliye hamen chahiye k ham koshish kren k ham instaforex jese achay broker k sath kaam kren ta k hamen trading k liye best spread mill paen aur ham bagair kissi tension k apni trades ko jari jari rakh saken

Dear brother ap nay thek kaha hay spread ek gap hay jo selling aur buying price k dermyan hota hay aur yah ek kism kar tax bhi hota hay jab ap trade open kartay hain to yah tax foran ap k account say kat lya jata hay, ap nay bi note keya hoga kah jab ap sell ki trade open kartay hain to trade opar wali price say start hoti hay aur jab ham buy katray hain to trade nechay wali price say start hoti hay.
