Price Arbitrage Opportunities: When to Take Them and When to Walk Away
On a crypto arbitrage scanner row, price arbitrage opportunities look embarrassingly simple: one exchange is higher, one is lower, buy cheap, sell rich, collect the crypto spread.
I have opened that trade—and watched unrealized profit look great until I tried to close. The gap was real. My edge was not. That lesson is the whole article.
What I Actually Mean by Price Arb
When I say crypto arbitrage between exchanges for price, I mean a hedged transport trade: roughly flat net delta, betting the cross-venue gap narrows or that I can exit the pair better than I got in.
That is not funding rate arbitrage (different animal). It is not a directional punt with two tickets. And it is not a gap you can stare at but never fill.
Before I call something a real CEX arbitrage price trade, I want three things: an actionable gap on spread tracking, liquidity on both sides, and a story for why the gap is here now—not merely that it has haunted my screen since last Tuesday.
When I Will Consider It: the Sudden Surge
The setups I still respect usually start with a sudden surge—liquidation wick, listing flow, someone fat-fingering size on a thin book. Something moved today, not "someday maybe."
Surges matter because other arbitrage perpetuals desks are often still working the dislocation. My horizon can be hours, not a prayer that a stale number mean-reverts.
Before I size anything, I pull history, not just the live tick. In ArbiSight I open Price Chart on the pair—you will find it on Live Crypto Arbitrage, on the orderbook view, basically anywhere you are comparing two exchanges. I am asking one blunt question: did this cryptocurrency price difference just spike off a calm baseline, or has it been parked at the same level forever?
A spike after quiet history is a trade I will think about. A plateau is usually wallpaper.
If I want a wider lens on how the gap has behaved, I hop to Spread Analysis for the two venues I care about.
When I Walk Away: the Gap That Will Not Die
Some pairs show the same price difference for many days. The free crypto arbitrage screener still lights up. I still pass.
In my experience, persistent gaps are often structural: withdrawals stuck, different index on the perp, listing weirdness, or exit liquidity so thin the market is effectively saying "keep your size." There is no guarantee it settles back because you were patient.
I leave it alone when the Price Chart is a flat plateau, when I cannot explain why the cheap venue is cheap, or when I already know the second leg will fight me on policy or margin.
The Orderbook Trap I Fell For (So You Might Not)
Even on a nice surge, I am much more careful about internal orderbook spread on each exchange. This is the part that burned me early.
The scanner shows a process difference—gross gap between mids or marks. Cool. But if that number is only a hair bigger than the combined bid–ask spread on both books, I am not looking at edge. I am looking at a mirage.
So I open long on the cheap venue, short on the rich one. Unrealized PnL goes green immediately—because marks love the middle of wide books. Then I close with market or aggressive limits and watch the profit vanish. I paid the spread on the way out, sometimes worse than on the way in.
My personal rule now is almost boring: sudden surge, gap clearly wider than both spreads, depth to get out. I estimate round-trip spread cost for my size on each venue, add fees and a cushion, and if the trade only works on mids, I assume I lose on fills.
If you want the longer version of reading books, I wrote How to Read an Orderbook for Arbitrage Entry Quality. In practice I confirm on Orderbook Snapshot before entry—not after green paper PnL talks me into something.
My Before-I-Click Checklist
I still use a list. Boring saves money.
- Spread just moved vs recent history (Price Chart says spike, not plateau).
- Net edge survives combined spreads and fees for my size.
- I can open and close both sides—no surprise close-only nonsense.
- Exit depth exists, not just entry depth.
- Perp funding and transfer costs are in the model if they apply.
- Jumpy book? I lean on Slow Entry instead of hero-sizing.

My "Nope" List
- Same gap for days, no catalyst I can name—no convergence thesis.
- Headline gap shrank but my simulated exit on the book did not improve.
- One venue widened the book or pulled liquidity mid-hold.
- Alerts say we are back inside my minimum threshold.
- Anything ops-related: API weirdness, margin creep, withdrawal friction.
When I am tired and tempted, I remember: crypto arbitrage earnings come from skipping bad trades as much as hitting good ones.
How I Use ArbiSight (Without Pretending the Scanner Closes for Me)
I treat ArbiSight as crypto arbitrage tools for discipline, not hype. Rough flow:
- Find movers: Live Crypto Arbitrage
- New vs stale: Price Chart on the row or orderbook
- Spread history: Spread Analysis
- Fill reality: Orderbook Snapshot
- Open risk: Portfolio Management
- Thresholds: Alerts and Watchlist
- Hold vs scratch: Arbitrage Profits
A free arbitrage screener row is a lead. Spread tracking plus honest orderbook analysis crypto arbitrage is what keeps futures arbitrage transport from becoming tuition.

Parting Thought
The best arbitrage scanner on earth will not click your exit button.
Trade the spike, not the plateau. Demand room after the book. And if unrealized PnL only looks good until you close—you probably already knew the answer before you clicked.
