Appreciate input from experienced traders, thanks in advance
On putting in a a calendar spread on NVDA Buy 1 lot Aug 30 175/ Sell 1 lot Aug 16 175, IBKR calculates roughly 40000 USD+ as margin !!.
account is Margin, not cash. It is not a US based account
Unable to get any sensible help from IBKR, is this actualy correct?
