open trade ke lot size main changes karna

Dosto boht sa logon ko is cheez ka pata nahi hota ka hum open trade mah lot size mah changes kr skta hain. mean agr app na iyk lot 0.75 ke lagye hoi ha app ko profit bhe da rahi ha tu app us main sa 0.50 ke close kr skta hain ya koi bhe size main jo app ke requirement ka matlibk ho kush hisa close kr skta hain baqi 0.25 ke reh jye ga ab app na is trade main sa 0.50 lot size ka profit already la chuka hon ga baqi 0.25 ko app next tp tak continue kr skta hain.

isa krna sa app ka profit be safe ho jye ga risk bhe kam ho jye ga next agr ya trade loss mah bhe jati ha tu app ko zyida nuksan nahi ho ga ur app ko spread ke mad mah kush bhe nahi dena para ga dobra trade lga kr.

Dear aisa krna sirf aik hi soort mein possible hy aur woh ye k ap ki trade loss mein chal rahi ho aur ap uski partial lot close krna chahein to ye mumkin hy aur agr trade profit mein ho to ap lot ko increase nhi kr sakty is mein yehi farq hy
