Stop All Order

[Al3cs]

Could be useful to have a "stop all" order in DOM that close all remaining position when price is hit.

So if you buy 100 shares and set a 100 shares SL, if you close half you have to cancel 100 shares SL order and create a new one for remaining 50 shares. With "stop all" you can set SL order and forget about it.

In general, we don't like adding our own order types and order management, especially for stops.  If the broker adds the given command, we can look at it. Different brokers tend to handle the situation differently. Many would not even let you place the sell order for 50 shares in your example if you already have an open order for 100, even if it is a stop order.
