have you witnessed this kind of patterns to actualize in the past
Most certainly. Examples are also on the link I posted. How does the saying go though? past results are not a guarantee of future projections something like that right? Another one I am watching is ENTB (do NOT plan on buying entb though, just going to watch the chart, do your DD before even considering a pink or anything else for that matter). Keep in mind that many factors can affect a technical play so watching the support/resistance and fundamentals are still required. Don't buy something just based on one factor. I like to see the whole picture myself.
Do your research! Play the TA. All posts are my opinion.
