Autotrader was adopted for newbie trader accounts. It will not install orders besides there is 10% or more profit, so any skills are ok. In the order of importance for fast ISK gain:
1) Skills increasing number of trade slots till at least 50
2) Margin trade 4
3) Accounting and broker relations 4
4) Connections 3
5) Level standing for station corporation and faction till at least 6. Courier bot can do this for 2-3 weeks.
I am now testing updated beta of
autotrader. You can set min funds to zero and bot will select proper value automatically for quite aggressive trade. Aggressive trade is better then safe trade when you have low ISKs in the beginning. Some of buy orders may be cancelled when you have low ISKs to feel the order. But you will efficiently use your margin trade skill.
