Overview

This error occurs when the market data feed is not activated for your trading account. Specifically, the data provider (DXFeed) requires users to sign the Market Data Agreement before access is granted.

Until this agreement is completed, DeepChart will not be able to establish a connection to the data feed.

Cause

The most common reason for this error is that the Market Data Agreement has not been signed for your account.

This usually happens when:

• The account is newly created

• Market data has not yet been activated

• The account is not registered as a Non-Professional user

Solution: Sign the Market Data Agreement

To resolve this issue, follow the steps below:

1. Identify the firm or prop firm from which you purchased or received your trading account
   (e.g., MyFundedFutures or another provider)

2. Contact their support team or dashboard and ask specifically:

   “How can I sign the Market Data Agreement (Non-Professional) for my DXFeed data?”

3. Complete the Market Data Agreement as instructed by the firm

   • Ensure you select Non-Professional status (if applicable)

   • Submit and confirm the agreement

4. Wait for confirmation that market data has been activated
   (This may take a few minutes to a few hours, depending on the firm)

5. Restart DeepChart and reconnect to the data feed

Important Notes

• This is not a DeepChart software issue

• Market data access is controlled by the data provider and your trading firm

• Without signing the agreement, the data feed will remain blocked

Prevention Tips

• Always complete market data agreements immediately after account creation

• Double-check your Non-Professional status

• Activate market data before launching DeepChart for the first time
