Margin for cash components like – Bonds – beragampengetahuan – Beragampengetahuan

Hi,
Request anyone to throw some light on the topic of pledging G secs and then utilising the margin of the same for trading FnO overnight positions. I want to create strategies which will be carried for a week or so, hence can i use the margin privided by G Secs for the same as the marging falls under Cash component. Or the 50 percent rule is applicable here as well. As when we pledge margin on stocks we can only use 50 percent of the margin and rest has to be in cash in funds.
Warm Regards
