I'm all for it. I think the added control of being able to pick and choose what coins get wiped is exactly what we need. I have funds tied up in two day old trades that could have been riding other waves all day long!
Can it maybe put a warning for people who may not understand exactly why they are doing it.. YOU ARE ABOUT TO EXCHANGE ALT FOR BTC ARE YOU SUPER SURE???
Honestly, if you didn't realize that your trading your bitcoin for alt coin I think you need to re-read the section, but I do think there should be some insight on the duration of the sell orders. It's usually between 6 hours - 7 days. Mine have been in a sell order for around 3 days now I got impenitent and lost some profit and sold some.
