What you need to know about crafting profits:

I feel it necessary to summarize these most important points...

1. Markup on resources increases how much you needto make to turn a profit so buy as low as possible.

2. Markup on finished goods definitely means a big difference so always sell for as much as you can. Also try to sell in person because half ped auction fees add up to big money in a years time.

3. Don't get greedy. Be satisfied with slow and steady gains.

4. Dont expect a hof or global is due and keep losing peds tryingto get it. If a run is very bad, move to another terminal or log back in in a few minutes. You would be amazed how much this has helped me. On the other hand if you have thousands of clicks to do then don't worry my runs have always averaged out if they are long enough.

5. Understand that globals and hofs are not profit rather they help smooth our a very volatile run.

6. Watch the orders regularly... I once saw orders for bam at around 280% at a time when it was about 190% market value... Rarely happens but on things not used or made much the orders can be significantly high if someone needs them badly.

7. You can almost always get a good deal on materials and ores by placing orders :) this significantly helps the quest for profits.

This should help you but I'll always add more info as I have it available.
