A web app for chart practice

Practice trading decisions repeatedly with historical charts.

Before making decisions in real trades, practice your own buy, sell, and stay-out decisions on historical charts one bar at a time. Review the reasoning behind each choice and what you would revisit next.

You can try the main features without signing in, using fictional sample instruments.

What is Chart Playback?

Turn what you have learned into practice for real trading decisions.

Learning to read charts and trading rules is different from making your own decisions as prices unfold. Chart Playback lets you replay historical charts one bar at a time without seeing what happens next. Practice deciding whether to buy, sell, or stay out as preparation for making your own decisions in actual trading.

Learn to read charts, practice buy, sell, and stay-out decisions by replaying historical charts, then review decisions to prepare for real trading.

Why practice?

Use your review to prepare for real-world decisions.

Look back at decisions and chart annotations to identify where you hesitated and what informed each choice. Test those observations in another practice session as you prepare to make independent decisions in actual trading. Practice does not guarantee trading results.

What you can do

Practice both buying and selling, then review your decisions.

Practice both buy-first and sell-first trades, including closing positions. Advance historical charts one bar at a time, consider staying out as well, and review orders, positions, profit and loss, and trade logs afterward.
