FAQ
Why can't I find an instrument?
Check the code/name is correct, try a shorter keyword (fuzzy search is supported), or click "All" to browse everything, and confirm your network is working.
Data loads slowly — what can I do?
The first load fetches a lot of data from the server; please be patient and watch the progress bar. Data is cached in the browser, so later actions are faster.
How do I delete a drawing?
Left-click to select the drawing, then right-click and choose delete; or click "Clear All" in the indicator settings panel to remove all drawings.
Stop-loss / take-profit did not trigger?
Check "Enable stop-loss/take-profit" is ticked, confirm the price or percentage is reasonable, and make sure time is advancing (playing or manual). It auto-closes when the price is reached.
Are my trades saved?
Yes, in your browser, so they persist next time. Clearing browser data will lose them, so export important records periodically.
Can I analyze several instruments at once?
The current version analyzes one instrument at a time; switching symbols auto-closes all positions with a prompt.
What is "watch bar formation"?
When enabled, stepping by the smallest timeframe updates higher-timeframe bars in real time, showing how a bar forms — closer to the live experience.
Does data update in real time?
The system shows historical data for replay analysis and updates weekly, not in real time. You can replay from any moment you choose.
How do I clear trading data?
Click "Clear Trading Data" at the top to remove all order records and P&L stats while keeping the K-line data, so you can restart practice.
