well then, if this noob guide is inaccurate, perhaps you would be so kind as to share a better set of tactics or guide.

Disparaging is easy - even moreso without anything to back it up.
I for one find the information of use. If you have what you feel is superior or more useful information, instead of knocking down a 'noob' perhaps you can spend quite a few more keystrokes to explain how your approach is a better one?

To the OP, I understand the market issue that the resources have to be SOLD to not be plundered, but am a little hazy on the BUY mechanics to avoid losing your gold.

Are you saying it is a timing event?
That you wait until the attacker is 15 or 20 min away from you, then BUY back as much of your resources as you can?

Or simply place ridiculously low bids? I mean I see the intent would be to tie up the gold in a pending transaction, but if that doesn't work on selling resources, would it work on keeping your gold safe when buying?

Or do you actually have to have completed the purchased to have the gold used up?
