Thanks yes I already saw that fee feature, great and intuitive idea. I feel that I just need to do the math so I can simply minimize fees. There are definitely opportunities.

Regarding Yobit coins, there are really many that are not properly named. I think if you fix it the users won't see that coin on yobit then. I would just put a disclaimer on your app's website that "some coins on Yobit have symbols (bcc, omi etc) like famous coins but in reality these are different coins than we usually know on bigger exchanges so be aware.". Just put a few examples there and users will understand. This happens mostly when I see the difference in the price like 20 000%. See images here:

1) I would like to see percentage between two exchanges after all the fees so I don't have to calculate it myself all the time. I can easily forget some fee and then there is a risk that my arbitrage won't be succesfull. I would like to see pure percentage after all the fees.

2) Definitely alerts would be nice so I can be notified by email when something pops up. I should be able to setup my own alert for example I should be able to choose exchange where I want to buy and exchange where i want to sell and percentage between them (something like lower then ..., or higher then....). Once it reaches my requirements I will be notified so I can buy immediatelly.

These are just some tips for now. I will be thinking of more features. Happy to help, you do a great job. Please let me know if you would like to get any feedback on something regarding to the app.

Thanks for your answer. Is there any exchange in your mind that has very low withdral fees please? Please keep up great work. Sometimes people are weird and don't appreciate if someone creates something useful. Once the tool has a bit more features I won't mind to pay for it but still need to figure out how to avoid fees. BTW. I noticed that Yobit site has some coins that have same symbols like famous coins for example BCC. BCC is bitcoin cash but on yobit it's bitconnect coin. The tool automatically pairs these coins and shows the difference in price but they are not the same! There are many like this on Yobit. Please be aware exchange.blue.

Great tool, thanks for that! I just don't understand one thing, can you help please?

When I buy cheap on one exchange then I sell it on another exchange I make a profit. But I still have my money on that exchange, I don't have them actually on my credit card. When I want to send the money to my credit card, everywhere are fees like 2% or even more! So I don't understand how you can make money on it basically.

Can you explain please?
