I know I've been on the dealing end. holding over the weekend isn't nfp tho, and you would have a better case on a swing trade to fuck them regulatory style we were always afraid of overshooting a margin call on the weekend, the house can get screwed.
having high leverage available has 2 very positive points. The first one as already mentioned is the avoidance of margin calls during an unexpectedly popping situation like you are pretty big in a trade and your software doesnt react or your broker is about to cheat you The second one is when there is this trade where you are in since quite a while and it is so profitable that you cannot lose anymore (you know those that you hardly have but so essentially need) and there is the chance to grasp for the stars in case you don't decide to do it better the next time
