Runescape

I've played Runescape for a long time. The GE was a nice addition but its very hard to try and make a profit off the GE since your trying to buy something at a lower price while others are offering more, the chances of you getting it are like 1/1000. I suggest training a trade skill like my 79 fishing and just make money by sell raw materials (Non cooked/crafted items) on the GE for min price.

I didn't use the grand exchange to buy and sell, when i used runescape I jsut used the grand exchange to buy whatever I needed... I did not sell much of my stuff ever lol.

Woah, I haven't played that for a year, my highest stat was Fishing, Level 91 and if I can recall I think I was level 112 Combat.

The GE prices don't really fluctuate fast enough to merchandise, but you can buy low and sell high if you really wanted to.

I have played RS for about three years now and at first admired the idea of a GE but was disappointed with the ban on unbalanced trades. About half a year ago, I came across this one method of making a reliable 4% return per transaction. It was to buy glass vials at two coins below the market average and sell them for two coins above the average. According to some theories on the Runescape economy, commonly bought items such as vials are able to shift around in price during the day and not change much in the overall market price. By riding this oscillation of demand for the vials, i was able to make a total of 14, 000,000 GP in about six months of just a few transactions a day.
It is common to make money in the same fashion with all sorts of items. If you sell your accumulated supply of ores after a mining session as minimum price to avoid the wait, then you are giving your money away to the people who are willing to wait the extra time just enough to make money. Every little bit counts if you want to merchant items on the GE. And in general, when dealing with the Grand Exchange and maxing your profits on a skill, time is money. The more time you allow for a transaction, the more money you will make. But this of course is a generalization.
