If you are noticing that the results are different for the ST Earnings Analysis Indicator in TOS versus in Tradestation, this might be because of the way each platform reports data around these events. 

The TOS numbers should always be correct. TS is not automatic in that you must manually tell the indicator if the underlying's earnings report is pre or post market. If you fail to do this the numbers will be wrong.
