I guess, if it will be implemented like how manually traders do for spotting arbitrage opportunity then your tool will be a huge hit among the traders who prefer trading across exchanges. I do compare a trading pair across exchanges by using coinmarketcap but their functionalities are not the updated one to reflect the recent price levels. If I am able to spot a gap that is most of the time due to frozen/delisted reasons.

In this modern era, I guess we traders are equipped with enough tools but improvements to those tools is definitely inevitable. Hope your services will be making us realizing how older versions we have been using so far or anything similar to that. Willing to test your portal asap. Good luck to surprise us .
