IBKR now charges absurd margins on VIX calendar spreads. According to CBOE the margins for tier 1 spreads (M1, M2) are $2200/$2000 and for tier 2 spreads ( M2, M3) $770/$700. In comparison IB charges $4860/$3888 for (M1,M2) and $10086/$8069 for (M2, M3). This makes no sense and definitely means I need to look for another broker...after 10 years![]()
Or trade one of the other 10,000 financial products available on IB...
