How does the Stop All work
You can use this particular type of stop order to limit losses by closing your entire position. This order can be combined with a normal position closing order, so that the execution of one cancels the other.
The Stop All is available only on BATS Europe, MTA and MOT and it is managed by Directa, who will forward it to the market only when trigger price is reached.
E.g. if the stock price of ENI drops to 23, sell ALL shares my portfolio at limit price equal to or less than 23.
If the trigger price is reached during the 'Closing Auction, the stop order will enter the order book only in the next day's opening auction (not in the After Hours).
