since Friday I have a problem with the required margins (as a broker I have ninjas). I'm being asked for overnight margins on both ES and ZB instead of intraday margins. I tried to write an email to Ninja's brokerage, but they replied to consult the margin page. It's a pity that on the margins page the daily trading foresees $500 for 1 ES lot and $1000 for a ZB lot, but nightly margins are applied to both of them. How can I fix?
Thank you
