How do I convert my Thinkorswim strategy into a custom scan?

The video on converting a strategy to a scan is helpful, but it doesn't quite resolve the issue I'm having. My strategy works very well on a select set of stocks. So before I trade a symbol, I first back test it over a 5 year period (daily). The strategy assigns a "score". If the score is at or above my threshold, I put the symbol in my trading watch list. Is it possible to turn the results of a back test into a scan to automate this screening process?

Well if it is a true chart strategy, there is no way to replicate that in a scan. But if you have a custom chart study that mimics the behavior of a chart study, then it may be possible to convert that to a scan. The issue is far more complicated than we can adequately address in the comments section of the Q&A Forum. And you may end up needing to convert it to a watchlist column to display the values computed for each ticker symbol. And this would need to be set to a daily time frame or higher, in order to have access to at least 5 years of historical data.
