Hi,
Everytime I cancel an order, and would like to make a new order,
I must refresh the whole page, please fix it, so I not need to refresh the whole page.

And for make buy order, would please make automatic calculation if I want to buy BTC for all value of my fiat.
Like btc-e, we just need klick the available fiat, and then the page will automatically calculate how many btc that will bought for specific price.
