How to use Chart Playback
Chart Playback is a tool for practicing what to decide at each point as you move through historical charts, then reviewing with practice orders and notes.
Start with fictional sample instruments
You can try the main features without signing in, using fictional sample instruments.
All displayed instrument names and price data are fictional samples, not real companies, securities, or market data.
Make decisions as you replay a chart
Moving through a historical chart little by little lets you practice what to decide with the information available at that point, without looking ahead at later price movements.
Use the on-screen controls or keyboard controls to move the visible position forward and back. Follow the guidance shown in the app for the available controls.

Record practice orders
Practice deciding when to enter or exit. These actions are for practice only; no order is sent to a broker and no real transaction takes place.
Review your positions, unrealized and realized profit and loss, and trade log alongside the reasons for your decisions and what followed. This is a central use of Chart Playback.

Review with drawing practice
Leave lines and notes on a chart to review what you noticed and why you made a decision.
Separate from practice orders, this is a way to record how you were reading a chart or which moments drew your attention. Review it later to organize your thinking.
