An app for trading cross exchanges?/大家需要一款可以跨交易所的交易软件吗？

Hi Guys, this is An, a developer at financial industry. Recently, I'm doing arbtrage trading cross multiple exchange markets. But the experience of it is not good. The problems I was facing are:

• Price checking cross multiple exchanges is very hard.
• Each exchange has it own UI
• The price is not fiat currency(USD) standard.

I would like to create an app to resolve them with below feature:

• Monitor markets data as a professional in our daily trading.
• Portfolio management.
• Cross trading.
• Find more arbitrary opportunities easily.

I'm not sure how many people need this App, so if you are interest in it please reply to me. And you can mention what kind of requirement you'd have, even the exchange's names that you are using, I will consider to adapt them by the counts.

Thanks.

大家好，最近做了一些跨交易所的套利操作，跨交易所的操作虽然有很多套利的空间，但是操作起来体验不是很好。我想做一个跨交易所的交易软件，不知道到家有没有这方面的需求。如果得话可以给我留言,对软件的需求和希望对接的交易所名称皆可。
