FYI I just noticed tonight that intraday margins were back for some of the asian indexes I trade, so I check IB's website and found the following announcement: "Due to the large differences in volatilities and liquidity in futures contracts, and in light of the unusual general market volatility, IB has temporarily suspended intraday margin reductions in certain classes of contracts, notably commodity sectors. Intraday reductions have been re-enabled for most index, debt, money-market, currency, and the most liquid commodity contracts. Please see below for the full list." I realize some people don't care about this and think intraday margins are for losers, but I thought others may be excited to hear this. Maybe IB can keep its finger off the trigger for a while now.
