When adding your API keys to the Autoview settings, you have the ability to give the keys an account name. This is meant for when you plan on using multiple keys for a single exchange. ie: run a bot for a friend or family member.
If you change the account name from the default '*', you will then need to call that specific account name in each syntax command.
If your account is the default, you could use:
e=poloniex s=pinkbtc q=100% b=buy t=market
If you changed your account name to "AccountName":
a=accountname e=poloniex s=pinkbtc q=100% b=buy t=market
