Error after new Coin detection

[kahnesaaron]

Ive installed the Bot some days ago, but today was the first time it was running while a new Coin was detected.
But I instantly got this error after the detection.
Is this an error on my end and i need to fix a lib or something?

The method list_trades() should return the current market trades.
see. https://github.com/gateio/gateapi-python/blob/master/docs/SpotApi.md#list_trades

It seems though, that none were available for the given pair, which caused the exception.
This is a problem on the bot's end and not on your end.

To prevent the exception, assert should be replaced with an if-statement and that returns an invalid price (e.g. 0 / -1) if no trades are available. (buy() needs to be changed as well then to verify the price)
Or return back to list_tickers as it was before (see 22748ee).

@CyberPunkMetalHead what do you think is the best approach?
