I'm thinking I might add a condition to the scan so that weekly MACD line must be above zero, what do we think?
The MACD sort of takes care of the upward momentum after the long term low, not necessarily having to wait for the GC.

So;
- 12 month low in the last 6 months
- C > 65ema
- Weelky MACD > 0

I can still run the GC scan if its required, but the scan above should be finding our pattern a bit better.
