How to start on Gravia
Short answer
Six steps: open the access flow, fund the underlying venue, build a widget layout, study one market, size with the Kelly calculator, and log every trade. The access gate is the only part that trips people up, and an invite link removes it.
STEP 1
Open the access flow
Gravia is invite-gated. Use an access link to open the flow directly instead of hunting for a code.
STEP 2
Connect your venue account
Gravia routes to Polymarket and Kalshi. Have a funded account on the venue you intend to trade — USDC for Polymarket, a KYC'd USD account for Kalshi.
STEP 3
Build a workspace
Add the widgets your strategy needs: Up/Down ladder for scalping, wallet research and flow panels for event trading.
STEP 4
Pick one market and study it
Before trading, watch one market for a session. Learn how its price reacts to flow and how fast the book refills.
STEP 5
Size with a calculator, not a feeling
Run the price and your probability through the Kelly calculator and take a quarter to a half of the result.
STEP 6
Log every trade
Record entry price, your estimate and the outcome. After 50 trades you will know whether your probability estimates are actually calibrated.
A sane first week
Trade one market type only. If you picked five-minute BTC binaries, do not also take three-month macro contracts — the skills barely overlap. Cap daily loss at a fixed number before you start, and stop when you hit it, because short-dated markets are engineered to keep you clicking.
What to look at inside the terminal
- Wallet history for the addresses driving the current move
- Spread and depth — not just the mid price
- Whether the same event is cheaper on the other venue
- Your open exposure across contracts, not per-position P&L
FAQ
+ Do I need an access code to join Gravia?
You need either a code or an invite link. The link opens the access page with the flow already started, which is why most people use it.
+ How much money should I start with?
Enough that fees are not a rounding-up problem but small enough that losing it is irrelevant. Many traders begin with a few hundred dollars and a strict quarter-Kelly sizing rule.
+ How long before I know if it works for me?
Around 50 logged trades. Fewer than that and variance dominates — you cannot tell skill from luck on a binary market in a dozen trades.
