@topotoolbox Very nice, probably these analyses are the best way to go about stock trading, but as always
"past performance is not indicative of future results"

Moreover, the guide does not explain on what assumptions and data it is based on, so I would not call this a very scientific approach.
The article just describes that under certain conditions the stock price may behave in a certain way and that it may be possible to predict such behavior; but no data regarding what this assumption is made on nor regarding its reliability is provided.
