Sorry to hear of your struggles Insearch. Unfortunately, I'm not surprised (I never signed up with them).
It seems to be a common scam to show results based on limit entry and exit orders, and we all know in trading the ES you basically must of price trade through your limit price on both exit and entry in order to get fills. When using a small profit target like they do (+.75 and +1.5), missing a few entries or exits totally destroys the reported results.
Every losing trade will always fill, but a certain percentage of reported winners will either not fill on entry or not fill on exit. And missing a relatively small percentage of the winners will easily make this kind of trading method a loser.
P.S. Thanks for sharing the results of your experience so others can learn from it!!
