@gephaest can you verify the numbers, i can see you are directly adding the usdc value in the tickers api. does this numbers look accurate to you?

@treeoflife2 Hi. In my first version, I added price conversion for better precision.

EXCHANGE_INFO_URL provides the actual active pairs, base currencies, and exchange rates. But if you prefer simplicity, stablecoins are close to a 1:1 rate.
On the other hand, I can’t guarantee that we’ll support only stablecoins in the future.

but you will still show the usd value of OI in exchange UI, so i think this is fine.

@treeoflife2 It depends on base currency of future. Now it only USDT/USDC
