how to use tick data

[existence]

Hi

I was hoping someone could advise me on this. I have looked at backtesting platforms like tradestation, amibroker, forex tester, all requires import of data in the OHLC format. Tick data does not have OHLC. So how is one suppose to utilise this tick data? Having said that, i think its possible for MT4 to use that by converting the CSV tick data file to HST format using a script, but there are certain limitations to MT4 to backtesting which excludes it as a choice.

Thanks
