Fix a missing Core indicator or missing chart drawings

Start by identifying what is missing. A script absent from the indicator list, a script with an error, and a working script without one particular box are different problems. Record the current chart before resetting inputs or removing anything.

Core is absent from the indicator list#

Open the saved Core script in Pine Editor and confirm that you added it to this chart. Saving the script and adding it are separate steps. If you are in a different TradingView account, check the account where you originally saved it. TradingView's first indicator tutorial explains the saved-script workflow.

Core does not appear through a Pro invitation. Use your purchase email's personal access link and Core installation instructions. If that email is missing, contact support with the checkout email. Do not try to recover Core through a Phantom Flow dashboard login.

Core is listed but has an error#

Read the complete error message. For an editor error immediately after installation, check for a partial paste or leftover placeholder code. Copy the complete script again into a new blank indicator. Preserve the original error and line number if it persists.

For a runtime error, note the symbol, exchange, timeframe, and the inputs that were active when it occurred. An error after changing one input is useful evidence. Avoid editing the script's calculations as a troubleshooting shortcut.

Core loads, but a module is invisible#

Check the indicator's visibility and its settings. Then inspect the specific control rather than enabling everything at once. In the reviewed Core defaults:

• Show Oscillator Columns is off, although the moving-average line and momentum candle coloring are enabled.
• Fair Value Gaps is off.
• Swing Order Blocks is off, while Internal Order Blocks is on.
• Daily, Weekly, and Monthly high/low levels are off.
• Premium/Discount Zones is off.

These defaults explain several common differences between a first installation and a screenshot with more modules enabled. Core's oscillator columns are part of the chart overlay, so a missing separate oscillator pane is not an installation failure.

A specific signal or old zone is missing#

A star requires two same-bar conditions. A gap requires its detection conditions and any active filter. An old order block may have broken or fallen outside the displayed count. Present mode intentionally limits retained structure drawings compared with Historical mode.

Compare identical symbols, exchanges, chart intervals, and settings. Two feeds with the same asset name can contain different candles. Also check whether the screenshot used Core or Pro; module names differ.

Send a report that can be reproduced#

Include the indicator title, exact error if present, symbol and exchange, timeframe, relevant settings, event timestamp and timezone, and a screenshot showing the problem. Explain the expected drawing and why you expected it. Keep the paid source and personal access URL out of public screenshots.

For alert-only problems, use alert troubleshooting. A missing device notification needs a different check from a missing chart drawing.
