I agree with those saying Poloniex's UI is not one that we should emulate to a tee. It's a decent interface, but not great by any stretch. The reason they are so popular is that they have almost any coin one might want to trade, they are US-based and trustworthy, and they get a lot more right than Bittrex (whose UI is a total abomination). So that's why Poloniex has been so successful and Bittrex is getting very little traction. Not to mention Poloniex has lending. Obviously we could greatly benefit from lending, but that is a big project and there is other lower hanging fruit, although hopefully a growing market cap will afford us the opportunity to work on more projects in parallel.
In any event, we should take what is good from Poloniex and improve what isn't so good. In fact, that's what
@svk has been trying to do and the UI has come a long way. I can't imagine the reference wallet is ever going to be a professional trading platform. That will likely have to be delivered by 3rd parties. I imagine even an MT4 integration will likely be delivered by a 3rd party. Either way, that is not going to happen instantly, and in the meantime there are obviously improvements we can and should make.
For example, we need basic position management capability (e.g. showing open positions with P/L, etc), which I started bringing up recently. We also need order types beyond the standard limit and market orders, such as stop-loss, stop limit, take profit, trailing stops, etc. The chart also needs a lot of work (especially the indicators), although I don't see it as the highest priority since it's not difficult to use external charting. So for the time being (until higher priority items are completed), basic charting without useful indicators is good enough.
Finally, the issue of multiple versions of the same base asset (i.e. BTC, USD, etc) is not caused by the interface. It's just the nature of the DEX. Although sidechains should help eliminate multiple versions of BTC and other digital assets. And perhaps much more liquid fiat BitAssets will help eliminate the need for the fiat IOU tokens. In the meantime, the way the markets are grouped now should at least help in this regard. I think we should give
@svk credit for a lot of excellent work on the UI. Let's keep making progress.
