As traders, ultimately what we are is risk managers, within the confines of our trading capitals. Many in this board continues to support IB's right to set margin as whatever they want. Yes, they do have that right. My issue is the arbitrariness of IB's actions. And because of that arbitrariness, IB becomes a risk to it's customers. If we are simply day trading, it doesn't matter much. It's unpleasant. Many will rightfully view it as constrained ability to take advantage of the current market situation and so on. But there are traders that may be shaken out of positions because of the arbitrariness of the margin. If CME sets margin at 12k, and every broker in the world has it at 12k or less, how can IB set it at 34k?
IB becomes another risk factor to it's customers. A risk that must me managed. Another risk like it's liquidation algos gone wild
