I have been trading for a reasonable amount of time now and I am just opening a discussion here on what trading tactics you use and how you profit from it.

For me, I just simply wander through trade.tf, picking out potential bargins. And I also buy craft hats for around 1 ref and resell it for 1.33 to make some profit. As I have learnt that its best to make alot of small profits rather than one big profit because it is simply just quicker.
