Let's wait and see. If Ighor enriches his app with charting, then his product would for sure be of interest to exchanges.

Bucketshops are paying hundreds of thousands of dollar to get Metatrader as a front-end for their clients (and partially a back-end for themselves). Why wouldn't bitcoin exchanges pay for having a decent front-end for their clients?

As far as I know there is currently one application, rtbtc, that has charts and order execution - the end user pays 20 bucks a month (rtbtc charts are very basic and low-quality).

Ighor follows a different business model in which the exchange pays for the front-end. In my opinion Ighor's product has potential (quality-wise, if charts are added) to kill rtbtc.
