Hello,
which details do you need?

After the update from WL17 to WL18 my strategy does not work anymore. I get different results.
I am currently trading with this strategy.
Can I go back to WL17 so I can trade with this strategy again?
I want to trade with the strategy again tomorrow.

regards

Sure you can go back to B17 if you saved the installer.

So the strategy "doesn't work anymore" or you get "different results"? Confusing. Until you post the strategy settings applied, strategy code/Blocks, screenshots of results (and how you determine the difference if B17 isn't installed), there is positively nothing to work with. 🤷‍♂️

Although you can get good clues from our detailed change log page:
https://www.wealth-lab.com/Software/ChangeLog

These important fixes are breaking changes:

* Fix - Previously, the PSAR indicator occasionally plotted inside a bar's range, and acceleration increased for every bar - even when a new high/low was not made.
* Fix - "N Bars Ago" Qualifier Building Block was not properly resetting the index, which affected conditions in the same block that followed it.
* Cleaned up more indicators so they do not plot before their first valid bar containing data.

You emailed us some screenshots with your Strategy's Blocks and I noted the usage of "N Bars Ago" in it. Like I said yesterday, B20 includes a fix for a bug in the 'N Bars Ago' block that was absolutely unacceptable to tolerate. Consider your strategy's performance under suspicion if it were using it in B17 and below.

Case closed.
