Here is a quick merchanting guide to how i make 15m+/day
First pick an item, make sure it has some demand and is with 5%+ and 5%-. I will post a list of items and limits at the end of this guide.
Buy one of this item at 5%+, then sell it for 5% minus. Right click on the Grand Exchange Clerk and select history. Here is an example of a rune kite:
As you can see our price margin is 34,501-35,687. We will use this margin to merchant!
You would buy 100 rune kites for 34,511 each and sell for 35,679 each. The reason you add a few gp is to outbid the other buyers decreasing the time buy alot and the profit by a little.
Here is an example of me merchanting archers' rings. I did this one quickly so the profit is not that big.
216,668gp profit for about 5 minutes of work because I rushed it. When you merchant make sure and be patient to get the maximum ammount of profit. Doing this on 6 items/ every 5 mins/ 24 hours is 374m profit in 24 hours. These numbers arn't realistic but, you get the point.
Items I like to merchant and there limits:
Limit: 100/4 hours
Limit: 5k/4 hours
Prayer Potion (4)
Limit: 10k/4 hours
Limit: 20k/4 hours
Limit: 25k/4 hours
Refer here to see all g e limits. You have to scroll down a bit
Remember, always be patient with merchanting it takes some time but makes tons of money. Try a bunch of items out and see what works the best. Try to make 2%+ per investment or its not worth the time. If there is a 25%+ price margin the item is most likely unstable so stay away from it.
Stopped playing for a year then got back into it for a month from scratch, here is some profit:
