To the best of our knowledge, Omega Research's software can read the CSI format, ASCII files, MetaStock and the CSIM format. Each of these formats has its own strengths and weaknesses, but overall, the CSIM format seems to work best with these products. Therefore, for analysis with Omega Research software (TradeStation, System Writer, Ti2000), we recommend you select CSIM format for your Export Format Files.
If you also use MetaStock (MS) format and MetaStock software, be aware that this software will modify the data files created by UA. If this causes a problem in your Omega Research application, consider using ASCII files.
