Partridge, the situation is the non-performance from OST/SBG. No answer from the legal department, not even an acknowledgement. You correctly state the issue of fund security - until I accept the new agreement I cannot trade, who takes the responsibility for losses incurred, should there be an open trade? A trader is forced into accepting just to complete a trade entered under a previous agreement. What would happen if a deal is struck under a specific law, but the the law is later changed...effectively retrospectively. Imagine the taxation laws being amended retrospectively. Furthermore, a legal document should be precise. Is my request for a response to much? The service I received from OST in the has always been good, that seems to have come to grinding halt, probably due to the nature of the concern.
