Set up the session
- Account size and leverage. Type your starting cash and pick 1×, 2× or 4×. Buying power is shown underneath — it’s simply cash × leverage.
- Mode. Single Ticker means you pick the name. Scanner Day surfaces the premarket movers for you (see Scanner Day).
- Ticker symbol and trading date. Any US equity, any day the desk has tape for. If the date isn’t available you’ll be told before you start.
- Start time (ET). Optional. Leave it blank to begin at 04:00 premarket, or use the Jump to chips.
