This is a little lesson on Instant-flipping.
Some of you may know what it consists of but this is a basic description.
This is what my G.E box usually looks like when Insta-Flipping.
I then sell the nats when i get around 15K of them come through just to keep a nice buy/sell flow.
The 4hr limit on these is 25K. Sell after buying to 'reset' your limit.
This method is approximately 500K an hour and you only need around 5M to start.
To find the buy/sell prices buy a nat around 5%-10% over market to work out what the instant buy price is. E.g you buy for 200gp and recieve 10gp back the instant buy price is 190gp.
Therefore the buy/sell prices should be around 188/189 or 189/190.
Just remember the price varies every 10 hours or so. E.g price changes from 168/169 to 169/170 or vice versa.
If you are cautious on whether you have found the correct buy/sell price, try with 100 nature runes first rather than flipping 25K.
Once you get the hang of your buy/sell prices the runes should buy/sell pretty quickly. You should buy/sell 2K natures every 5-10secs on average.
This method works with other items aswell such as food, logs and other runes.
If needs be i can run through this 'one-on-one' with you at the G.E via pm. By that i mean i will find prices for you and tell you exactly how much for/how many to buy although it would be nice if you do a little bit of experimenting, and finding out how to work out instant buy prices.
More coming soon or when im back from vacation.
