I noticed an issue earlier in the week and finally had a chance to finish writing it up. This is a case where we should be emulating Poloniex because they are getting it right. Basically, when you click on the order book, you are generally looking to do 1 of 2 things: either 1) you to want place an order on the book, or 2) you want to match one or more orders
already on the book. The buy/sell windows should be populated accordingly, but that's not happening. And it's far more problematic than most would imagine.
As an example (see image below), if you click the 4th row of the ask side, you are either looking to place your own ask onto the order book at that price, OR you want to match the orders on the ask side
up to that price. So 2 things should happen: 1) the sell window should be populated with the price you clicked in case you want to place an order on the ask side of the book at the clicked price, and 2) the buy window should be populated with a) the
price you clicked, b) the
sum of the share amounts on those first 4 rows, and c) the
sum of the prices of the shares available on those 4 rows. This allows you to see how many shares are available up to the price you are willing to pay before either clicking buy or clicking further down the book if you need more shares.
Not having the order book behave in this manner is a major drawback. In my estimation this is one of a small handful of things that is preventing Bittrex from getting much if any traction at all. In any event, please check out Poloniex to see how it should work. Hopefully we can get this into the next update. Thanks
