Set the league so the green links open the right Trade2 search.
Read the question under Walk the tree. Click a green link, look at the cheapest listing, then answer yes or no.
Type the three prices above before you spend anything. Continue only when the sale is higher than the cost.
Yes means do the next step. No means stop.
Early in a session the gold vendor or the Currency Exchange is sometimes cheaper than trade for one stackable currency. The profit is that gap. It closes the hour other people stand in it.
Hard stop: A gap of a fraction of an exalt on a slow currency is not a job. If you cannot turn the stack before the price moves, leave it.
No fixed currency. Compare the vendor or the exchange with trade, in the same unit, and flip one stack only while they differ. When the prices meet, stop.
Cost to follow the tree
—The cost is the stack you buy. The sale is the other side of that same currency, the same hour.
Buy
Whichever side is cheaper right now: wisdoms, augmentations, chaos, or any other stack the vendor sells. Recheck the pair before every stack.
Sell this
The other side of the same currency, in the same hour.
Session cost
One small stack. Stop when the buy price and the sell price meet.
Batch
One stack, then look again. A dead ratio is not a craft you push.
Walk the tree
Answer one question at a time. You can step back.
Decide
Did you search Trade2 for both sides of one stackable currency (vendor or exchange, and trade) sold this week?
Same base + the keep mods. Ignore week-old listings and a single huge vanity ask.
Open the exchange and compare the two sides of one currency.
The finished item is only worth more than the materials on the day you check. A magic item that already has two useful mods is the start. A white base you Transmute is a different, usually losing, craft.
Once the two-mod batch is too small for the bankroll, the product is a base that already has the expensive mod locked. You buy that fracture from someone else. Fracturing it yourself is a separate bet, and it loses when the orb divided by the hit chance costs more than the spread.
If it already has the mods buyers search for, list it. If it is a magic item with two of those mods and an open affix, it can enter the batch. A blank rare is a vendor.
