Data Feed Connection Problems
Data feed issues can throw a wrench into your trading. If your charts stop updating or start showing missing candles, every second can feel like an eternity – especially in fast-moving markets.
What Causes Data Feed Errors
Several factors can lead to data feed issues, and understanding them is the first step toward resolving them.
- Internet connectivity problems: Even a brief network hiccup can disrupt MultiCharts’ connection to your data provider. This is particularly common with less reliable residential internet connections.
- Outdated software: Running older versions of MultiCharts can cause compatibility issues with data providers like IQFeed, Interactive Brokers, or TradeStation. As Henry MultiCharts from MultiCharts Support notes:
Latest versions address known data feed issues, including IQFeed connection drops.
Many traders skip updates, unaware that these updates often fix known bugs and connection problems. - Server issues from data providers: Routine maintenance or high traffic on the provider’s servers can result in connection failures, causing delayed updates or gaps in your charts.
How to Fix Data Feed Issues
If you’re dealing with data feed problems, here are some practical steps to get things back on track:
- Update MultiCharts immediately: The MultiCharts support team frequently releases patches to address connection issues. As Henry MultiCharts explains:
We have implemented an updater to fix IQfeed dropping data issue.
Always download updates directly from the official website instead of relying solely on the built-in update checker. - Close all MultiCharts-related processes before updating: This includes processes like
MultiCharts.exe,MessageCenter.exe, andQuoteManager.exe. Closing these ensures the update installs correctly. - Press Ctrl+R to refresh the feed: This simple shortcut can "wake up" a stalled data feed during active trading sessions.
- Collect diagnostic logs for persistent issues: If the problem continues, gather logs, screenshots, and workspace files to assist support. MultiCharts logs can be found in
%USERPROFILE%\Local Settings\Application Data\TS Support\MultiCharts\, while IQFeed logs are located atC:\Users\User\Documents\DTN\IQFeed\IQConnectLog.txt.
If on-site fixes don’t resolve the issue, consider upgrading to a more robust infrastructure like QuantVPS.

Script and Strategy Compilation Errors
When custom trading strategies fail to compile and throw error messages instead of generating signals, it can disrupt your trading flow. Addressing these script errors is crucial to keeping your trading operations running smoothly.
Most Common Script Errors
MultiCharts script errors tend to fall into a few predictable categories.
Syntax errors are by far the most common. Simple mistakes like missing semicolons, unmatched parentheses, or incorrect variable declarations can prevent your strategy from loading. For instance, typing If Close > Open then instead of If Close > Open then begin can bring your script to a halt.
Variable scope issues often trip up traders. Declaring a variable inside a conditional block and then trying to use it elsewhere can trigger an "undeclared identifier" error. This problem frequently arises when copying code snippets from forums without fully understanding how variables are structured.
Maximum bars lookback problems occur when your script requires more historical data than MultiCharts has allocated. For example, if your strategy references 500 bars but MultiCharts is set to only look back 50, you’ll encounter errors or incomplete calculations.
Session time conflicts arise when the trading hours in your script don’t align with the platform’s settings. This mismatch can prevent time-based conditions from triggering as intended.
Reserved word conflicts happen when traders accidentally use system-reserved terms like "Close" or "Volume" as custom variable names. This results in compilation errors since these terms are already defined by MultiCharts.
How to Fix Script and Strategy Errors
Resolving these issues requires a methodical approach. Here are some practical steps to get your scripts back on track:
- Read error messages carefully: MultiCharts provides detailed error descriptions and line numbers. If you see messages like "Syntax error, unexpected symbol", focus on the indicated line. Often, the fix is as simple as adding a missing semicolon or correcting a bracket.
- Increase maximum bars lookback: If incomplete data errors occur, right-click on your chart, select "Format Strategies", and increase the "Maximum number of bars study will reference." Setting this to around 1,000 bars usually works for most strategies.
- Use debugging tools and test on historical data: Leverage the PowerLanguage Editor debugger to step through your code and monitor variable values in real time. Testing your strategy on historical data can uncover logic errors and ensure entry and exit conditions perform as expected across various scenarios.
- Declare variables at the top of your script: To avoid scope issues, declare all variables at the beginning of your code. Use
Vars:for persistent variables andVariables:for those used temporarily within each bar. - Check session templates: Ensure that your session settings align with your trading hours. For instruments with overnight sessions, update your session template to ensure time-based conditions work correctly.
- Validate input parameters: Double-check default values for input parameters. For instance, if your strategy uses a moving average period, make sure it’s not set to zero or a negative number, as this can cause errors or nonsensical results.
These steps can help ensure your scripts run smoothly, reducing downtime and improving platform performance.

Platform Crashes and Slow Performance
When MultiCharts crashes or slows down, it’s not just a minor annoyance – it can lead to missed trades and financial losses. If the platform freezes during market hours or crashes while you’re managing active positions, it directly impacts your ability to trade effectively.
Why MultiCharts Crashes
Crashes often happen when your system runs out of resources like CPU power, RAM, or disk space. MultiCharts processes data, calculates orders, and updates charts in real time, all of which place heavy demands on your CPU. If the workload exceeds your system’s capacity, the platform may freeze or crash.
Memory usage is another common issue. Every open chart, active strategy, and data feed requires memory. Running too many charts, especially with extensive historical data, can push your system’s RAM to the breaking point.
Corrupted workspaces and settings can also trigger crashes. If your chart layouts or strategy configurations are damaged – often due to improper shutdowns or system errors – MultiCharts may crash repeatedly when trying to load those files.
Conflicts with other software or outdated drivers can create instability as well. For instance, antivirus programs scanning trading files in real time or outdated graphics drivers struggling with multiple monitors can lead to crashes. MultiCharts includes a Fail-Watch system to alert you when system resources, hardware, or network limits are being pushed too far, giving you a chance to address the issue before it escalates.
How to Fix Crashes and Performance Issues
To improve stability and performance, start by optimizing your MultiCharts workspace. Reduce the number of open charts and limit the range of historical data displayed. This lowers the strain on your system resources. Avoid opening unnecessary windows during high-load periods, as each additional window increases data processing and memory usage.
If you notice alerts like "Long delay in the calculation of studies", it’s a sign that your strategy code needs attention. Simplify your code by reducing inefficient loops, shortening lookback periods, or streamlining complex calculations.
Keep an eye on your system’s resource usage. If MultiCharts consistently uses a large portion of your CPU or RAM, consider scaling back your workload or upgrading your hardware.
Finally, update your drivers and software regularly to avoid compatibility issues. For more robust stability, you might also consider using a dedicated solution like QuantVPS.

Broker Connection and Order Problems
Broker connection failures or issues with order execution can throw a wrench into your trading operations.
Common Broker Connection Issues
One of the most frequent issues traders face is login errors. Even if your credentials are correct, MultiCharts may fail to connect due to your broker’s server status or network issues. It’s not uncommon for brokers to experience outages, especially during high-traffic trading periods.
Another common snag comes from time zone mismatches. For example, if your platform shows 9:30 AM but your broker’s system registers 10:30 AM, your orders might be rejected or executed at unexpected times. This is particularly problematic during daylight saving time transitions, as different regions adjust their clocks on different dates.
Incorrect broker profile settings can also cause connection failures. Every broker has specific requirements for data feeds, order routing, and account configurations. Using outdated or incorrect profile settings can prevent your platform from communicating with your broker’s systems effectively.
Additionally, firewall and antivirus software can interfere with trading software. These programs often flag trading platforms as suspicious due to their frequent data requests and order commands, blocking critical connections.
Just like data feed or script-related issues, maintaining a stable broker connection is crucial for seamless trading.
How to Fix Order Execution Problems
Start by ensuring your platform’s time is synced with your broker’s time. You can do this through the Format > Instrument Settings menu.
If you’re experiencing issues with live orders, test the same orders in a demo account. If demo trades succeed but live orders fail, the problem might lie in your account permissions or buying power.
Double-check your trade sizes and contract settings. Order rejections often occur when your position size exceeds your account’s margin requirements or when it doesn’t meet the broker’s minimum or maximum order limits. Make sure your settings for round lots, tick sizes, and multipliers align perfectly with your broker’s specifications.
If connection problems persist, update your broker profile. Download the latest version from your broker’s website or MultiCharts’ support section. Brokers sometimes update their server addresses or API requirements, which can render older profiles incompatible.
Lastly, ensure your firewall and antivirus software allow the necessary ports. Add your trading platform to the trusted applications list in your security settings.
