BTW, today I see a huge gap in SPAN blocked (4x more) for hedged positions in the account vs. margin calculator.
This is in my (wife’s) account.
I checked this yesterday night. Thought I would wait till morning if it gets corrected. but no.
I opened a ticket. Hoping that it would be addressed in rightful manner 
At the time of taking these positions I had more than 10% of capital un-utilized. Yet, by dawn, the difference.
For exact same positions, the margin blocked is way less in other broker account (samco in this case).
