Pick a trading day to practice
Practice is a one-click, account-less $100,000 sandbox for any past session, and the clock is yours — jump to the open, scrub forward minute by minute, or rewind. Live instead trades today's session against the real market through a live account; there the clock is the real clock. For your first run, click Start Trading, pick a recent date, and you'll land mid-morning with the rest of the day ahead. (Once a strategy is proven, a bot can trade it for you.)

Read the option chain
The center of the screen is the option chain — every strike with its calls and puts, each showing the bid, ask, and live delta. The strike nearest the current SPX price is at-the-money. Option chain & Greeks covers how to read every column.

Build an order
Click a cell to add a leg to your ticket; add more to build a spread or an iron condor — every leg fills together as one atomic order. Then choose a type: market fills right away at the natural price, limit only fills at the level you set, and stop waits for a trigger. Before you commit, the ticket previews the fill price, fees, and buying-power impact. More in Orders & order types.

Track your position
Once filled, the trade shows up in Positions with live P&L, delta, and a payoff chart across the range of SPX prices. In practice, advance the clock and watch it mark to market. At 4:00 PM ET the day settles automatically — in-the-money options exercise, out-of-the-money options expire worthless. See Positions & P&L and End-of-day settlement.
