My proposition is
1. remove trading range at all or
2. provide clear rules for "additional clearings" which change the trading range so users can calculate the risk
If you do additional clearings arbitrarily you effectively change the trading range at will. Many people have margin calls that they wouldn't have if additional clearing was not done. In effect they feel that arbitrarily done clearing "margin called" their accounts. No clear rules for additional clearings justifies their feelings.
Allright, proposal nr.2 accepted. I will outline the draft of the rules soon.
currently, the additional clearings are a scam.
I have lost all of my financial confidence in icbit - this is no less than the second major round of huge price "manipulation" this time fueled by the apparently new automated margin call execution - This is definitely resulting in losses to smaller investors. this coupled with the "additional clearings put investors at far more risk than intended - this is theft. The nonchalant attitude of icbit suggests they have something to gain from this.
I believe that I can no longer trade at icbit. The lack of concern for investors' money is flagrant and alarming.
