This monster stop is useless because it can wipe out 10% of your account.

In my FXCM 10000 Euro demo there is a similar trade with a much smaller stop:
{XAG/USD:BB:s7902} Short 1@18.3680 Risk 41$ ts at 20:12:01

Another question is, why should I hide the stop from my broker? If you think your broker tries to trick you out, you better look for another broker. Usually I trade my systems with more than 1 broker because 1. it is an easy way to monitor the quality of your broker and 2. a desaster can happen everywhere. I noticed that over time the quality of a broker can change. My favourites in the moment are ActivTrades, JFD and LMAX.
