With regard to yuor order at 0.00116, I sympathize. When you're trading, a lot of lowball orders aren't filled. Thankfully, the market usually gives you a second chance. There was one for Bitshares late this afternoon (Eastern time) when you could buy all you wanted at below 1175. As I write, it's shot up to 1267.
You'll have your second chance at cheap STEEM. "There's always another one on the way."
That always happens to me on Poloniex!
And it's always good to know!
