What keyword margin means?

Margin keyword
Is it total available margin with perticular broker or required margin for perticular strategy?

Margin keyword is not active, so pls do not use it

Hello Sir. since “Margin” keyword is not active in Tradetron. What is the alternative to this if we wish to exit when the PNL or MTM crosses e.g. 1% or 2% of the margin available. Guess definiing the MTM in absolute terms would not help since premiums keep fluctuatiing. Moreover different strategies with or w/o hedge would also have diff. margin requirements. pls. help
