Auto-flatten
Closing everything at a Breach - what it promises and what it cannot.
Auto-flatten closes every open position on a Protected account the moment a Breach is detected. It is a Pro and Premium capability, on top of the Lock, and it is off unless you switch it on.
What it promises
That the closes are attempted from the server, at the instant the engine sees the Breach, without a browser being open. What comes back - which positions actually closed - is what the venue confirmed, and anything still open after it is named rather than assumed away.
What it cannot promise
A fill. A close is an order and a broker fills it at the price the market offers, which during the move that caused the Breach may be some distance from the one you saw. It also cannot act faster than your broker answers.
The exit that survives everything - this product being down, your machine being off, the network being gone - is the stop loss resting at your broker. Auto-flatten is a layer on top of that and never a replacement for it.
