Overview

The DATA_ACCESS_SUSPENDED error appears when DXFeed suspends market data access due to a mismatch in your Non-Professional status.

Although the user may have signed the Market Data Agreement as a Non-Professional, DXFeed may determine—based on the information provided in the agreement—that the user does not qualify as Non-Professional.

Cause

This error occurs when:

• You signed the market data agreement as Non-Professional

• DXFeed’s compliance review determines that your submitted information does not meet Non-Professional criteria

• As a result, market data access is suspended

This decision is made by DXFeed, not by DeepChart.

Solution: Verify Non-Professional Status With DXFeed

Step 1: Contact DeepChart Support

Reach out to DeepChart Support and report the following error:

DATA_ACCESS_SUSPENDED

Step 2: Request the Non-Professional Verification Form

DeepChart Support will provide you with a verification form that confirms your Non-Professional status.

Step 3: Complete and Submit the Form

• Fill out the form accurately

• Ensure all information clearly confirms that you are a Non-Professional trader

• Submit the completed form back to DeepChart Support

Step 4: DXFeed Review

• DeepChart Support will forward the form to DXFeed

• DXFeed will review the documentation as proof of your Non-Professional status

Step 5: Data Access Restored

Once approved by DXFeed:

• Market data access will be re-enabled

• Restart DeepChart and reconnect the data feed

Important Notes

• This is a compliance-related issue, not a software bug

• Approval time depends on DXFeed’s review process

• Providing accurate and truthful information is essential

Prevention Tips

• Carefully complete all Market Data Agreement fields

• Ensure your details match Non-Professional eligibility requirements

• Avoid inconsistencies in employment or trading activity information
