About this market

What is SOL Up/Down 4h?

SOL 4-hour windows capture a whole session of Solana ecosystem news, and the book tends to stay wide until the third hour when direction becomes clearer. Four-hour windows run on fixed boundaries, giving six markets a day. Each window spans a regional trading session — Asia, Europe, the US morning — so the Up/Down binary is effectively a bet on who wins that session.

Solana is the volatile one of the family. SOL's price follows on-chain activity — memecoin launches, launchpad volume, validator-client news — and it frequently moves in bursts rather than smoothly. Over a 4-hour horizon that means more windows that look decided early and then reverse, and a book whose resting liquidity retreats quickly when volatility rises.

With only six windows a day the sample size grows slowly, but each window carries real information: the Up price moves in steps as new data arrives, and liquidity providers show up with size. These windows are good for testing trend-following signals and for studying how the book anchors to intraday session behaviour.

What moves SOL 4h Up/Down

Memecoin and launchpad turnover, which drives fee revenue and speculative demand together
Network incidents and validator-client upgrades
Window structure: regional session handovers — Asia into Europe into the US — which is where intraday direction usually changes

FAQ

SOL Up/Down 4h: common questions

What do the SOL 4h windows cover?

Six fixed four-hour windows per day, each of which spans a regional trading session. sol-updown-4h markets resolve independently of the shorter windows, so you can compare a 4h book with the four 1h books inside it.

Is there enough SOL 4h history for a backtest?

Yes — six windows a day since 2025-06-01 is about 3,072 resolved markets. That is thinner than 5m or 15m, but each window carries many more book updates, so it works well for per-window features.

What moves the SOL 4h Up/Down price most?

Two things dominate. First, memecoin and launchpad turnover, which drives fee revenue and speculative demand together. Second, network incidents and validator-client upgrades. On top of that sits the structural driver of every 4-hour window: regional session handovers — Asia into Europe into the US — which is where intraday direction usually changes. Liquidity here is thinner than BTC and ETH, with visible gaps between price levels in quiet periods.

How does SOL 4h Up/Down compare with the SOLUSDT order book on Binance?

Binance is where price discovery happens; Polymarket prices a probability on top of it. Joining sol-updown-4h with Binance SOLUSDT spot and perp ticks on timestamp lets you measure how many milliseconds the Up price lags a spot move. See the Binance SOL spot and perp pages for the matching feeds.

How big is the sol-updown-4h dataset?

About 2.09M events recorded since 2025-06-01, or roughly 4,091 events a day across about 3,072 windows. Every event carries both exchange and receive timestamps.
