Correct because the maximum leverage ratio associated with a position
financed by the minimum margin requirement is one divided by the minimum margin
requirement. Hence, the value of the position (100%) is divided by the minimum margin requirement (45%); 100% / 45% = 2.22
问题1：minimum margin requirement我的理解是自有资金的占比，如45%的requirement，要求100元的投资中有至少45元是自己投入的，这样理解对吗？
问题2： maximium leverage ratio指的是D/E吗？为什么用答案要用100%/minimum margin requirement？
