Hello,
I've exported to MT4 tick data from 1.1.2009 - 15.9.2014, but when I tried backtesting in MT4 I got an error - "no data for testing"
I found a post here that said that this issue is due to a limitation that MT4 has with not supporting databases (FXT files) greater than 4GB.
So I re-exported the tick data for a smaller period, and turned on the "filter duplicate ticks" option to get smaller FXT files.
Now the backtesting works without an error, but tickstory still shows in the "earliest date" and "last date" columns the old dates (for the longer period).
How can I reset all the downloaded/exported data for a symbol and start clean?
Thanks

Re: Reset exported data
Hi Shani,
The earliest/latest dates you see in Tickstory denote the range of tick data that you have downloaded from the internet. This is different to the date range you exported to MT4. If you want to check the date range you have exported to MT4, use the Historical Data Center in MT4.
Regards.

Re: Reset exported data
Thank you for you reply.
A few more questions:
1. If I exported a certain time period to MT4 and then I need a different time period I just do an export again and the old MT4 files will be overwritten, right?
2. If the new export doesn't contain the old dates than this data will no longer be available for MT4?
3. If I exported the data from the past 2 years until last month and I want to add the data from last month I need to do an export again for the entire date range, correct?
4. What is the "filter duplicate ticks" option for? why would I have duplicate ticks? Will the becktesting give me different results if this option was selected on export or not?
Thanks again

Hi Shani:

That is correct.
2. If the new export doesn't contain the old dates than this data will no longer be available for MT4?
That is correct - if you export again then only the date range you select will be available. The previous data will be overwritten.
3. If I exported the data from the past 2 years until last month and I want to add the data from last month I need to do an export again for the entire date range, correct?
That is correct for the moment. The next generation of Tickstory will be able to append to existing databases.
4. What is the "filter duplicate ticks" option for? why would I have duplicate ticks? Will the becktesting give me different results if this option was selected on export or not?
