Best f2p items to INVEST in (not flip)

[printerfaxer]

Recently I have been trying my hand at investing, rather than flip merchanting. I bought 410 amulets of defence, and 97 black hatchets, as the hatchets are currently at a very low point, and the defence amulets are already rising.
More importantly, i bought them because they are items that seem to have very predictable [glow=red,2,300]'wave'[/glow] patterns in their price fluctuations.
If anyone knows of other items with large wave-like fluctuations as well, please post all of them, it will be greatly appreciated ;D

hey there. i'm kinda new.

btw, beware of patterns. instead follow trends.

how do you figure out a trend.

it's the change of an item over a long period of time...factors tend to change over time and you'll know it when u see it.
