Our platform uses CoinMarketCap rates directly, without adding any extra percentage on top, ensuring users always trade at fair market prices.
Well, the development of the platform is going at a surprisingly good speed.
If I may suggest, in the table with active offers, it would be really useful to see the current exchange/price rate per CMC (or which service is considered adequate). So, for example, in order to check how much is realistically offered for 0.00013327 BTC to XMR, I have to open CMC and possibly a calculator to get the precise amount. If there are several offers at some point, it can be tiring to check for each one.
Given that you are already using the CMC API, and if I correctly recognized Tradingview as well, I assume that it does not require too much work to implement.
