Poloniex now has stop-limit orders..
Can someone explain to me how or what these are for someone who really does not quite get it?
I would like to know that too.
Me too!

Also is anyone getting minimum sell levels? In otherwords you go to sell something but it says it must be above 0.001 BTC total?
In normal stock trading, stop orders is triggered when the price goes below or above the market.
For example, you bought 1000 PMC for 1 BTC and your sell stop is at 0.5 btc to cut your loss. That means when it is traded at 0.4 btc which is below your sell stop it will sell all your 1000 PMC at market value, basically dumping all your coins.
In my experience in trading, it is not good to put a stop order. If you are a trader, it is better to manage your winner than your losers. If you use a stop that means whenever the price is going down you are taking it out to cut your loss, you can always wait for it to go up.
