One little correction and they jack it up 20%. Imagine what it will be if we roll over into a bear market. By doing this they will chase off some traders, thereby having an adverse effect on the firm's liquidity. Some will say they are being careful. Maybe they are but there are other ways to hedge.
What a load of crap.
If you think a 10% margin requirement in a 4% daily move environment is too much, you have some serious thinking to do.
If during overnight trading the thing collapses 7% on only 5% margin requirement on a full margin use, you would be complaining the next day that the liquidated too late and you have a 2% deficit on your account.
People complain too much without understanding the risks...
PS. I did get a notice of increased margin reqs.
