Quick Start

A guided walk-through from "never opened DataMaxi+" to "made my first read on a spread", in five minutes. Screens shown are the current redesigned UI on dev.datamaxiplus.com.

1. Sign in​

The site landing page leads with a single CTA — Sign in. Click it (top-right of datamaxiplus.com) to reach the terminal login screen.

Sign-in screen

You have two ways in:

  • Continue with Google — single-click OAuth, easiest for personal accounts.
  • Email + Password — fill the two fields and click Sign in. If you don't have an account yet, click Create one at the bottom; the sign-up flow uses the same shape.

Forgot your password? Use the Forgot password? link to reset by email.

After signing in you land on the Dashboard.

2. Read the Dashboard​

The Dashboard is the entry screen — one-glance market read with shortcuts into every other section.

Dashboard

What's on it:

  • Header KPIs — aggregate open interest, count of tokens at extreme funding, BTC + ETH market cap.
  • 24h Volume by token (treemap, left) and Open Interest by token (treemap, center) — cell size = share, color = 24h price change.
  • Liquidations by token (right rail) — window pill (1H · 4H · 24H), long/short split per token.
  • Top premium · Extreme funding · Negative funding (bottom strips) — each with a View all → jump to the deeper screen.

Use the Dashboard as your starting screen each session, then jump from a card into the matching tool.

3. Find a spread on the Premium screener​

The Premium screener ranks every cross-exchange spread that matters. Open Premium from the left nav (or the Top premium → View all jump on the Dashboard).

Premium — base view

3a. Pick the venues you trade​

Top-left of the table, click All exchanges ▼. Tick the venues you actually have keys / balances on — the screener filters to pairs where both legs are in your set.

Premium — Exchanges multi-select

3b. Pick a direction or strategy​

Two pill rows above the table:

  • Strategy — All · S-S · S-Perp · Perp-Perp · Perp-S. Picks which legs are eligible (spot-spot, spot-perp, …).
  • Direction — All · Kimchi · Overseas. Click Kimchi to narrow to KRW-market spreads (Upbit / Bithumb on one leg).

Premium — Kimchi-only view

3c. Filter for what you can actually execute​

Open the Premium Settings rail on the left. Useful starting filters:

  • Premium ≥ 0.5% (or whatever your edge is) under Ranges.
  • Src vol and Tgt vol ≥ $1,000,000 to drop illiquid pairs.
  • Transferable only toggle at the bottom — exclude pairs where the asset can't be deposited / withdrawn on one of the venues.

The result is a short list of pairs that pass your trade rules — open the inspector on any row to commit (see Premium → Inspector).

4. Check funding-rate regime​

Open Funding Rate from the left nav (Derivatives group).

Funding Rate grid

Two reads at a glance:

  • Top Funding Rates / Bottom Funding Rates strips at the top — current extremes across the whole token universe. Tells you which side is paying hardest right now.
  • Cross-venue grid below — one row per token, one column per venue. Sort by Funding Gap to surface the biggest carry edges instantly; pair the high-paying venue (short) with the low-paying venue (long) to collect the gap.

For a token you'd want to set up: click the row to open the inspector — per-venue rate cards + history chart.

5. Sniff for listing arbitrage​

Open Listing Arb from the left nav (Arbitrage group). Three tabs along the title:

  • Active — live KRW-market listings; rare but high-edge.
  • Historical — every past listing, ranked by post-listing move. Use this to size what's normal.
  • Expected — listings that haven't gone live yet — pre-position keys, balances, and bots before the announcement lands.

Listing Arb — Historical post-mortem table

Click any historical row to open the per-event post-mortem (/listing-arbitrage/<venue>-<symbol>) — deposit status, opening price, spot + perp markets, funding strip, Telegram mentions. The single best place to learn what the next opportunity will look like.

Arbitrage basics​

New to arbitrage? The terminology can feel overwhelming at first, but don't worry — the DataMaxi team will walk you through the basics.

Let's start with the key terms.

What is Arbitrage?​

Making profit from price differences of the same asset across different markets.

  • Simply put, it's the strategy of "buying low and selling high" simultaneously.
  • Example: Buy Bitcoin for $95,000 on an overseas exchange → Sell it for $96,200 on a Korean exchange, earning $1,200 in spread.
  • The risk is low, but fast execution is crucial.

What is Kimchi Premium?​

Short for "Kimchi Premium" — a phenomenon unique to Korean crypto markets.

  • It occurs when crypto prices on Korean exchanges (Upbit, Bithumb, etc.) are higher than on overseas exchanges (Binance, etc.).
  • For example, if Bitcoin is $95,000 overseas but $96,200 in Korea, there's a 1.26% kimchi premium.
  • Why does it happen? Higher demand in Korea compared to overseas, or due to exchange rate fluctuations and deposit/withdrawal restrictions.

What is Funding Rate?​

A mechanism in perpetual futures markets to balance long (bullish) and short (bearish) positions — think of it as an interest system.

  • Positive (+) funding rate:
    • When longs are dominant → long position holders pay a fee (funding) to short position holders.
  • Negative (-) funding rate:
    • When shorts are dominant → shorts pay longs.
  • When the funding rate is high: It signals "lots of longs are betting aggressively" → can be seen as an overheating signal.

Beyond these basics, there are many more arbitrage-related terms depending on the strategy and market conditions.
