I certainly understand that the trades are the trigger and in fact, this stop order should have been triggered. I have had stop orders trigger and my fill not at the stop level. I have no issues with this and understand that the stock can move below the trigger price. In this case, the stop should have been triggered and a trade executed. It did not happen. That is of concern to me if I have a broker that does not always honor my stop orders and also refuses any pecuniary liability for their failed system. I have attached a portion of their response below and am interested if anyone knows if the SEC has any requirements for a broker to fill a stop order.
From IB:
In your correspondence, you ask IB to provide an explanation of how the bad market data prevented your Stop order from triggering when the conditions of the order were met. In addition, you ask IB to forward instructions to escalate your complaint. Upon receipt of your correspondence, the IB Compliance Department further reviewed the facts and circumstances surrounding your complaint and provides the following response.
On December 3, 2009, LAVA was disseminating bad market data and crossing markets. IB wishes to remind you that IB must simulate Stop orders for listed stock.
Please note the Simulated Order disclosure posted on the IB Website, "IB simulates certain order types (for example, stop or conditional orders) where an exchange or other market center does not natively support such order type. While simulated orders offer substantial control opportunities, they may be subject to problems relating to performance of third parties outside of IB control, such as market data providers and exchanges.
Although we attempt to filter external data to ensure the best possible execution quality, IB cannot anticipate all of the reasons that a simulated order may not receive an execution, or may receive an erroneous execution. Unsatisfactory (non) executions may result from events, including erroneous, missing or inconsistent market data; [ii] IB data filters (example: we may ignore last sale data that is reported outside the prevailing bid-ask as it often represents untimely or erroneous transactions; this may impact triggering of simulated orders); [iii] transactions subsequently deemed erroneous by an exchange; [iv] market halts and interruptions."

My main concern is that a stop is the main way I can ensure that I do not suffer a major loss if I am away from my system and a stock starts to decline in value (or vice versa). What else can a simple trader like myself do if a stop is not honored, a loss in value occurs and the broker says they are not responsible?
