however in ccxt 4.3.4

    import ccxt
    exchange = ccxt.bitget()
    symbol = "TONCOIN/USDT"
    data = exchange.fetch_ticker(symbol)
    print(json.dumps(data, indent=4, default=str))

throws error

ccxt.base.errors.BadSymbol: bitget does not have market symbol TONCOIN/USDT

I have to use TON/USDT

is this intended change of behavior

Code

Hello @edwardchenchen,
Yes we did that override because most exchanges refer to it as TON and not TONCOIN. If you want you can revert it by doing this exchange.commonCurrencies['TONCOIN'] = 'TONCOIN' right after instantiating the exchange.

[edwardchenchen]

ok, I see how it works, and it also opens lot of possibilities to fix what I am currently doing workarounds.

e.g
https://www.bitget.com/support/articles/12560603808156

exchange.commonCurrencies['OMNI'] = 'SOMETHING_ELSE'
exchange.commonCurrencies['OMNI1'] = 'OMNI'

so I can make changes to any symbol to make it consistent across all exchanges

[carlosmiei]

@edwardchenchen That's exactly what commonCurrencies is meant for, just make sure you set the overrides before start using the unified methods or calling load_markets
