Three rooms on one practice desk: spot, perpetuals, and the basis that ties them together. Fictional listings, priced on your device around the clock; a funding clock that turns over every eight hours; not a real dollar anywhere. What you leave with is a working sense of how orders, leverage and funding behave. Markets Price, turnover and a one-day sparkline for every listing, with sector filters, movers and search. Behind each, a chart with six timeframes, moving averages and a synthetic order book. Spot Market orders fill at once. Limit orders rest at your price on the lower maker fee and fill on the same deterministic path when you return. Sizing is a slider. Perps Long or short on isolated margin, 1x to 20x. Take-profit and stop-loss on the ticket, the liquidation price shown before you confirm, close half or all. Funding settles at 00:00, 08:00 and 16:00 UTC — longs fund shorts when the perp trades rich, shorts fund longs when it trades cheap. Basis The room most apps leave out. A board ranks every listing by basis, funding rate and annualised carry, with a countdown to the next settlement. The carry builder buys spot and shorts the perp 1x in one tap, then shows both legs and the funding accruing until you unwind. Desk Your balance and its curve, the two pools, a full history with CSV export, a session report that reads your habits back to you, and a field guide with a glossary. All of it is practice. Prices, mark prices and funding rates are generated on your device and track no real market; nothing real is bought, sold, held, deposited or withdrawn. Start fresh in Settings returns the desk to its opening balances. Nothing here is investment advice. Watch the clock, and learn what eight hours costs.
