Wonderful! Thanks for making an awesome guide, I'm trying to get an Ancient Katana myself.
One suggestion though, I personally wouldn't keep a ledger because gaia already does that for you. Just hit the
log button under your avi in your store. However, I can see keeping a ledger for items bought in the exchange forum. Cool guide though, best I've seen so far.
If you don't do much trading, then you can rely on the transaction log associated with your store, but if you do a lot of trading, items often roll off the bottom of the list before you have put the item up for sale. The transaction log only lists your most recent 100 transactions. The marketplace log includes bids on other selllers' items (whether you win the item or not), items you won or purchased, items you listed for sale, items you canceled, and items that sold. So if you buy 30 items, put the items up for sale, and successfully sell all the items, you would have filled 90 lines of the transaction log. If you do any bidding or if you have to cancel and relist any items, you will quickly have items roll off your transaction log. I often buy and sell 50 to 100 items per day, so I cannot rely on the transaction log for this information.
For me, having a spreadsheet of the items I have bought and sold for the day provides a lot of information. It shows purchase price so I can choose a profitable selling price, price trends through my trading period, average profit per item, and my percent return on each item. I can also look back over the past several days and see which items really moved quickly and others that sort of stagnated.
