[Logic] Trading of asset disabled by issuer

[MarkoPaasila]

This error message:

 File "/usr/local/lib/python3.5/dist-packages/grapheneapi/graphenewsrpc.py", line 173, in rpcexec
    raise RPCError(ret['error']['message'])
grapheneapi.exceptions.RPCError: Assert Exception: is_authorized_asset( d, *_seller, *_receive_asset ):

means that the issuer of the asset we are trying to trade has disabled trading temporarily or semi-permanently. This doesn't happen so often, but when it happens it will frustrate many users. We should handle this error properly either by

1. displaying the user a message and stopping the affected worker, or by
2. slowing down and retrying once every hour until trading is resumed.

Any other ideas?

interesting, in my (non DEXbot but pybitshares using) scripts the error was

RPCError: Assert Exception: _sell_asset->options.whitelist_markets.find(_receive_asset->id) != _sell_asset->options.whitelist_markets.end()

same thoughts though; assertion arguments are very confusing for the user

@MarkoPaasila shall we close or this issue still a concern?

[MarkoPaasila]

It's pretty rare, but also simple. Just one specific exception. Backlog?
