Reading Lighter markets on Robinhood Chain…
What Glassy does
Market quality, measured where you trade.
A market maker judges a venue by what sits behind the price: how tight the quote is, how much size waits a few levels down, and whether the quote holds when price moves. Glassy takes the same readings from public books and puts them in front of you before you send an order.
Nine venues, one screen
Lighter on Robinhood Chain sits beside Hyperliquid, Lighter, Aster, dYdX, Paradex, Binance, Bybit and OKX, on the same yardstick.
Your size, their cost
Type an amount and Glassy walks each book level by level to show the fill you would get, with the venue's fee added.

How far the spread wandered over the last minute. A quote that widens the moment price moves is a quote that leaves when you need it.

The bad minute
The widest spread and the thinnest book each venue has shown since you opened this page, with the clock time it happened. An average hides exactly this.
