Genuine question out of passing interest. I am a six sigma black belt and have a good grasp of statistics. When we look at statistically significant trends, run & control charts / correlation etc you need to have a statistically significant sample sizes. You also need to factor in common and special cause variation.
Presumably for charts to work you need a certain volume over a period of time for them to be more accurate and is someone is buying or selling out of character / trend (special cause variation) they become less viable / reliable and as with six sigma your confidence level (95% for six sigma)) drops
Last few days volume has not been overly high, it does seem hard to buy shares, there hasn't been any news, we don't know how many people are buying (lots of individual trades or 1 /2 investors building a position).
So does anyone know the criteria under which charts work better than tea leaves
