Tickstory

Dear all,

I exported an 8GB CSV file of tick data, but I can’t import it into MT5(Version 5.00, build 5370, 17th Oct 2025 in Windows 11).
I successfully imported 1-minute bar data from a CSV by clicking the Bars tab, but I can’t import tick data using the Ticks tab.

The CSV format is as follows:
Timestamp,Bid price,Ask price,Bid volume,Ask volume
20120112 01:02:10:100,1.24233,1.24271,1.1,1.2

I can’t even see the data in the preview window after clicking the Import Ticks button.

Here are the things I’ve already tried:
1. Set Tools → Options → Charts → Max Bars in Chart to Unlimited, and restarted the terminal for the settings to take effect.
2. Confirmed that I selected the correct date range and that both the start and end dates are valid.
3. Since 8GB might be too large, I extracted the first 1,000 lines and tried importing that, but the result was the same.
4. Changed the column headers in the CSV to match MT5’s expected format (i.e. Timestamp → Date, Bid price → Bid, Ask price → Ask).
5. Extracted the first 1,000 lines first, then changed the headers accordingly.

Does anyone have any idea how to fix this?
Thanks in advance!

Hi Kenmaxnejp,

Please use this guide for importing data into Metatrader 5. When you select the file, MT5 should show you the sample of the data being imported which indicates it recognises the data format.

Hope this helps.
