Given that CSV and MT4 use two different formats, you will always need to reproduce the extract twice in some way or the other. When you say “re-download”, do note that Tickstory only downloads the tick data once from the web. After this, the time taken to generate your data is attributed to writing to the desired file format.
thanks, i couldn’t find that addressed in the manual or forum.
may i ask here about the best format for FSB, i do not see an option for ‘tick’ only ‘bar’. does this mean that testing in FSB is necessarily less granular/worse than a tick-based system (like Amibroker, or even MT4 with Tickstory) ?
As far as I am aware, the most granular data that FSB uses is 1-minute bar data. If this is the case, then yes, it would be less accurate if your trading system is tick-sensitive.
To export to FSB you will simply need to use the ‘Forex SB Bar format’ which will output bar data in the selected time-frame (eg. 15-minute, etc).
