What the hell?!?!
That the hell is wrong with the user interface?!?!!
You evil stupid bastards! You have cost me 300 dollars or more!
When I click "cancel all orders" I expect all orders to be cancelled!
When I click "buy", I expect order to be executed!
It took a minute or so until the system accepted that I demanded for the orders to be cancelled and then several eons until I was able to type in a simple MARKET ORDER for which there is NO BUTTON; but anyway, the price has run away by more than 15 dollars in the mean time, so I wish you many nightmares.
Seriously.
You must be kidding!
P.S. I already heard some wealthy people complaining about your buggy system and only now I understand what did they mean. Of course, they are no longer on bitfinex.
OK, while I have no interest in responding to you, because I find you rude, in the interest of giving information to others, I will.
Clicking "cancel all orders" does in fact cancel all orders. It first asks you if you are sure that you want to do so. This is a protection in case you accidentally hit it, and then find you have canceled potentially dozens of orders which you have to re enter. When you are creating an order, you can create orders of different types. If the button said "buy right now no matter the price", you would be justified in assuming that pressing that button would execute immediately. This is also not the strategy that most professional traders would use. So, when crafting your order, we allow you to send a limit order, because if the price is at 425, but the next order is at 500, we don't think it is ideal to have your order instantly execute at 500, when most people wouldn't expect that. If you want to buy at literally ANY price, with a market order, you are free to do so, by changing the type of the order from "limit" to "market".
If you haven't figured out how to use the tool you are using, it might be better to learn how to use it before needing it suddenly. Anyone who has traded on Bitfinex for more than a day, realizes that the order types is in the drop down, and you can change it for your style of trading.
So, have a good day.
