One platform, from free to full automation: see every spread, trade it in one click, or let the engine trade it for you. Here is exactly what each tier does — feature by feature.
See the market before you pay anything.
Sign in and look around — the free tier is a working slice of the platform, not a time-limited trial.
A free account streams the same live table with the major exchanges: Binance, Bybit, OKX and Gate, plus MEXC, Bitget and Aster once you sign in. History is capped at the last hours and funding shows only the recent payouts — enough to watch how spreads move. The full exchange list, coin search and deep history unlock with the paid plans below.
The trading panel, orderbooks and positions all run in demo on every free account: practice balances, fills simulated against the real orderbooks with real fee math. Open hedged pairs, close them, watch the PnL — no exchange account, no API keys.
See the whole market — every spread, every exchange, live.
For traders who hunt opportunities themselves: the complete real-time picture with nothing hidden, plus the alerts group so the market comes to you.
One table with every coin that trades on two or more of the exchanges we track. Six tabs cover every setup: Long+Short (futures vs futures), Spot+Short (buy spot, short futures) and Long+Spot (long futures, sell spot) ranked by price spread — plus the same three ranked by funding rate for carry trades. Live data, updated every few seconds.
Type a ticker and see every pair for that coin across all exchanges, on every tab.
Up to 30 days of spread history on every pair chart. Scroll back and analyse how the token behaved before — how often the spread opened, how wide it got and how fast it closed.
Up to 90 days of funding history, side by side across exchanges. Before you carry a position for funding, check how stable the rate actually is: does it hold its level across settlements, how often it flips, and what the real APR was over the period.
One exchange lists 1000PEPE, another lists plain PEPE — same coin, prices 1000x apart. Arbiline knows they are the same coin and lines the prices up, so the spread you see is the real one and the size that goes to each exchange is right. On a fresh listing with an unusual multiplier you can set it yourself, per side.
The market comes to you: every opportunity lands in a members-only Telegram group with the whole picture in one message — the coin, both exchanges, the spread, volume and funding on each leg, deposit and withdraw status, and the next best routes for the same coin. Separate threads for Long+Short, Spot+Short and funding, so you follow only the strategy you trade.
See a spread, take it — one click, both sides, covered.
For traders who trade it themselves: enter the spread you are looking at without switching between exchange tabs, track every position with PnL that already counts fees and funding, and keep protection running on both sides 24/7.
Everything in Data, plus:
Every number in the panel is calculated for the trade you are actually about to make: both orderbooks are walked to your position size and your real fee tier on each exchange is applied, so the entry and exit percentages already account for depth and commission. Pick the size, set leverage per side, and one button sends both orders at once.
Every pair you open shows up in one place with the numbers that matter: the spread you actually captured, PnL with the fees from both sides already subtracted, and funding as it accrues. Each side is checked against the exchange itself, so the position you see on screen matches the one you really have.
Make a bot in Telegram, paste its token into Settings once, and everything that happens to your positions lands in your private chat with that bot. It is your bot and your chat — nobody else is in it, and you can cut it off any time. Switch each alert on or off and set your own thresholds:
Losing one side without noticing is the scariest thing in arbitrage trading: a liquidation, an ADL or an accidental close on the exchange leaves you with an unhedged position, fully exposed to the price while it moves. Protection watches your open positions 24/7 on our servers — it keeps running when your browser is closed. The moment one side disappears you get an instant alert, and — if you turn it on — the remaining side is re-hedged or closed for you automatically.
The engine trades while you sleep.
For traders who want automation: define the entry, let per-pair monitors watch both books 24/7 and fire the pair atomically the moment your spread confirms.
Everything in Trader, plus:
Set the spread you want and the size — the engine does the rest. It watches both books non-stop and opens the trade only when the spread is really there. Run it on the entry, on the exit, or set both targets and let auto mode cycle: it opens when your entry spread shows up and closes when the exit one does — perfect for coins where the same gap keeps coming back.
