"Charts (and TA) is 100% accurate when telling you what has happened" (unless it's PTSC and you get a wrong closing quote from, let's say, Schwab).
Anyway, to americanbulls.com credit, in your BSC example, they were correct with candlestick analysis for BSC two weeks ago.
But the strike I have against their method is that in some cases you are supposed to know that the opening price will be the day's low... and you are supposed to buy in at that price to get the results they post on the 'two year signal history'.
