We have seen that reversal operations can be dangerous because in a day we can have more than one for instrument, and at a certain moment operations will be without stop loss. In the commection with C2 is interrupted, this can result in a 'without limit risk' for customers.
So reversals are discarded from today. Stop losses are now more tight than before. This will imply that there can be some operations with little losses. The alternative was to put large stop losses with some 10%, that is not acceptable.
