The two volume columns
These are the raw hourly trade counts, and they are not interchangeable — each one fills a
different side of your flip.
Buy fills/hr (the API's instasells) — how many units per hour other players dump into
buy orders. This is what fills your buy order. Low here means you wait to get in.
Sell fills/hr (the API's instabuys) — how many units per hour players instantly buy.
This is what fills your sell offer. Low here means you get stuck holding stock.
You need both. Your real throughput is the smaller of the two, which is what
Bal measures: min ÷ max. At 1.00 both sides clear at the same speed; at 0.30 one
side is three times slower and inventory piles up on you.
Round trip
How long one complete cycle of your entire bankroll takes — buying in, then selling out:
qty/(buyFills × capture) + qty/(sellFills × capture)
where qty = bankroll ÷ buy price. So it answers: "if I put all my coins into this, how long
until I'm back to coins with profit?" A 12-minute round trip means about 5 full cycles per hour.
This is the number that decides whether something is rinse-and-repeat or a leave-it-overnight play.
Coins/hr
min(capital-limited, market-limited). Capital-limited is what your bankroll can
turn over per hour given the round-trip time. Market-limited is
margin × min(buyFills, sellFills) × capture — you can't trade more than the market moves.
Capture is your assumed share of that flow, since you compete with other flippers and bots.
20% is a reasonable default. Every coins/hr figure scales linearly with it, so slide it to taste.
Flags and the NPC tab
MANIP = spread above 35%, or a suspiciously round price. A wide spread on a liquid item is
usually a wall someone is holding, not free money — if it drops while you're holding, there's no bid
underneath. Hidden by default.
NPC rows sell to an NPC rather than back into the bazaar, so the sell side is unlimited (shown as
∞) but two hard limits apply instead: a 500M coin/day NPC sell cap, and the fact that you must
physically carry items (2304 per inventory trip). Trips/day is shown next to the name.
Click any row for the full arithmetic on that item.
Queue depth — will I get outbid?
Straight from Hypixel's own order book, and the best predictor of whether you'll spend the
session rebidding:
buy queue = items resting in buy orders ÷ fills per hour
That's how long the orders ahead of yours take to clear. Under ~6h you place an order and it
fills. At 48h you can't wait, so you outbid — then someone outbids you by a coin, and it never stops.
The market median is around 47h, so most items are congested.
Orders is the raw count of competing buy orders. 30 is quiet; 900 is a bidding war.
Watch both legs. A long buy queue just means you wait on coins. A long sell queue means
you're stuck holding items you can't offload — that's where losses come from.
Beware: profit rank and competition rank tend to be the same list, because everyone reads the same
public rankings. The best flips are usually a little further down.
