Selling asap is not always the best choice, so manual trading should be kept as an option.
For example, a coin may be going up in price but profitability may be going down instead, because of difficulty or block reward.
Personally, I think manual trades are what makes middlecoin what it is.
Sorry if I often name MC but it's the de-facto benchmark for btc multipools and I'd really like to have an option to them, this be clevermining would be fine :-)
