I was looking at just trying to trade plex. You make very little profit, but the volume is so high that you make moneys.
This was my math:
So I did some number crunching with plex.
Buy: 3,075,106.01 ISK
Sell: 3,191,929.88 ISK
Plex fluctuates between 5% and 2% margin between buy and sell. It is impossible to make profit in Jita, but in perimeter, you get taxed 0.5% to 0.3%, so you can make profit off of plex. Currently, there is a 3.6% margin, and then subtract the tax, and that’s your profit. I rounded down to a clean 3% for losses and other fees.
With the 5 bil im willing to spend, I can buy 1625 plex. If you buy low sell high, you can make ~154,547,851 isk per buy/sell cycle.
If you add the buy and sell value you get 210664 plex being traded a day. Thats 653,058,400,000 worth of plex a day. That means I am only trading 0.7% of the daily trade volume.
Based off of trying with small amounts of plex, I can get my stuff bought and sold within 10 minutes. With the volume, right now there is ~154 plex being traded a minute. That means if I am always on top, that is a buy/sell cycle every 11 minutes. I will round to 15, because im slow. That is 4 buy/sell cycles a hour. If you keep trading that 5 bil worth of plex without buying more plex to trade, you make ~620 million isk a hour. If you keep trading, the amount you trade will keep on climbing along with the isk/hr you make.
What am I missing?
