More question for 'Symbol' key

as I dig deeper into the API response from one of the exchanges, I found that even for most popular trading pair market, there happens to have duplicate symbol keys, in cases like this, what would be the recommended handling? should I keep both by changing one of the keys?

Thanks

symbol is not what you are looking for. You should be looking for the string that represents the trading pair. In this particular case, you should be looking at currency_pair_code
