    - **Known MT4 issue**: In some cases there are known issues with the Strategy Tester. The Tickstory & MT4 forums are often a good place to read about issues that people have come across. Examples of such issues include the "4GB FXT limtation"​ which limits the maximum period you can test in the Strategy Tester at one time. Other similar issues do exist, and often will have some workaround which will allow you to continue your back-testing with this issue in mind.    - **Known MT4 issue**: In some cases there are known issues with the Strategy Tester.

    - **Bug in Tickstory**:​ In the event you believe there is an issue with Tickstory, the implication is that Tickstory has exported incorrect data in some way. For example, perhaps you believe the "​Open"​ price of a bar is incorrect. In this event, please clearly demonstrate this with screenshots of the charts and/or Historical Data Center so we can investigate further. Please do not just provide us with a copy of your EA and ask us "​What'​s wrong?",​ as we are unlikely to be able to assist since understanding your code and further debugging could take many hours of our time. Instead, distill as much information as you can that allows us to work with the data itself. If, for example, your moving average indicator is giving you the incorrect value, this should easily be demonstrable by showing the incorrect data points versus what they should be. This sort of targeted information is invaluable for us to investigate and identify any issues as soon as possible. ​    - **Bug in Tickstory**:​ In the event you believe there is an issue with Tickstory, the implication is that Tickstory has exported incorrect data in some way.

 +==== FXT - Cannot open error [5] ====
 +If this error occurs, please check the following:
 +
 +  - Make sure you have the correct MT4 Settings in your FXT file by using the method described [[http://​tickstory.com/​forum/​viewtopic.php?​f=2&​t=809|here]]. ​ This includes making sure that your "Map to" symbol is *exactly* as it appears in MT4 - including the correct case.
 +  - Make sure you have exported more than 100 bars for the time-frame you are working in.  For example, if you are working in the daily time-frame, export more than 100 days of data.  If you are using the 1 hour time-frame, make sure you have exported at least 100 hours worth of data (i.e. 5+ days) and so forth.
 +  - While trouble-shooting this error, make sure you don't have more than 4GB FXT files (you may try go beyond this once you have resolved the issue, but do note that MT4 does not always handle > 4GB FXTs very well).
 +  - An invalid field somewhere such as a comma instead of a decimal place. See [[https://​tickstory.com/​forum/​viewtopic.php?​f=2&​t=809&​p=5381|here]] for more discussion on this.  ​
