I would think you want at least $10k in margin per contract, but that is just me.
Back to the subject at hand, I think a stoploss order with some huge amount of gap would be nice. My thoughts: 1) Use the combined/one-triggers-other order to setup a stop loss once the market order fills. This will stop loss will trigger if you happen to reside in washington DC and russia nukes it, and your connection happens to drop while the exchange is crashing. Maybe your nearest of kin can use the money? 2) Perhaps also include a market order to close position at a certain time in the near future.. say 15 minutes - in case you lose connection for a long time and you just can't do anything to remedy the situation (or you are away from the trading platform, etc). 3) Have the backend of JBT continually update the the stoploss and market-at-time type order so that they reflect the fact that JBT knows the latest price, and it has an active connection at the moment. Maybe update the timed order once a minute, and the stoploss order at some smart combination of time/price movement to keep the order update rate low? 4) When the position is closed, all residual orders are closed. This would produce a robust system where there is no interference with the strategy unless the connection is dropped, or the price drops insanely fast (which could happen as an exchange error, for instance). If you wanted to implement a trailing strop for your strategy, that would be written at the strategy level.
