A few notes on EtherDelta (exchange platform)

I posted this once or twice over on r/ethtrader but since Etheroll is currenly only trading on EtherDelta, I figured some folks could use this info. Please read carefully... might save you some cash.

The price is astonishingly low now considering that DICE/ROL isn't on any major exchanges and hasn't really even hit the consciousness of most ETH holders. Now's a great time to buy from the 8% of people who are selling.

(1) if you transpose your trade, you will get screwed... seriously screwed. The interface is a little confusing and it's possible to transpose the values. If you do this, you will buy a very small amount of what you want for a very large price. THERE ARE NO SAFEGUARDS AGAINST THIS (except you).

(2) When making an order YOU need to determine the quantity you are buying or selling. On many other exchanges you can put in a price and a total value and it will do the math for you. Not here... time to get a calculator out or do the math in your head.

(3) Their trading system does not work like normal exchanges. They only support "Resting Orders". This means when you submit an order it literally "just gets added to the list". Another human has to come along and "pick" that order from the list. (well, I'm assuming it's a human; could be bot).

This is why you will sometimes see buys for higher than the lowest sell. It's because their system is not a matchmaker. It is simply an order taker.

Likewise, if you see an existing order that you want to buy, you have to click on that order and buy it (or sell it, etc). You can't just "put in an order that will match with the price you want" and expect it to fill. You have to click the order you want to buy/sell.

(4) It seems that the site is easier to use and more reliable if you install parity and the parity chrome extension. My experience with Metamask was more buggy (but not terrible).

(5) If you're getting errors about "no private key" or "insufficent balance" click on your account in the upper right corner and select "Reset Cache" from the menu. 60% of the time this works every time.

Feel free to add/correct me if I'm wrong on anything here.
