Jab be ap koi trade open karty hain tu ap ko risk management pehly karna hogi. us ka faida yeh hota hai kay ap ko pata chalta hai kay ap har trade pay kitna risk involve kar rahy hain or ap kay pas bad mai kitna backup reh jye ga. es mai aik bat jo khas hai ager ap jab aik trade open kar daity hain tu ap nay 2nd trade jo open karni hai us ka risk level total capital sy nahi laina hai. ap nay pehli trade ki amount minus kar kay capital sy jo baqi bachy gi woh 2nd trade kay risk level sy nikalain gy tu ap kay pas 2nd trade ka sahi risk level amount aye gi.
