What kind of notification besides mail (I'm not too sure that works reliably and spam filters can be a bitch) would you suggest? Text messages? UI popups and flashes? Sounds?
If you know from the start how low you could go, I'm not even sure these notifications are needed, there could be specialized services to notify you if prices touch certain points...
Not cool to not receive anything though!
Just email, I have it set up on a specific email that updates every 10s for a god damn reason! I didn't even get a single notice (not even the usual email when trades are accepted, just awful). I used Bitfinex due to the stoplosses and emails because without it trading is extremely time consuming having to watch the ticker. Not receiving any margin call or notice whatsoever absolutely defeats the entire purpose I used this service for as I live an extremely hectic and busy lifestyle.
I initially read their FAQ and took it as truth. 2BTC down the drain. My fault I guess?
