Definitely not - better do not yet trade that system...

The main difference between 1.30 and 1.32 performance-wise is that you can not peek into the future anymore with a TMF. If your system had unrealistic profit prior to that, there's a good chance that this was peeking bias, often unintentionally caused by bad code in your TMF.

Of course that's just what I would immediately suspect, there can be many other reasons why a script has inconsistent performance. But all those reasons mean that the script is not fit for trading.

Don't feel helpless when encountering such a problem: The first thing to check is the log of the old and the new version. Look into a single trade, from open to close. There you can normally see the reason of different results.
