Here we have a Pattern that I found yesterday (PST). I was looking for a pattern completion around 1.91423. The best part of this completion was that I identified an Pattern, which is a 3 candle pattern that signifies a Reversal in trend in favour of the Bears. You can take a look at the specifics on this website (http://www.onlinetradingconcepts.com/TechnicalAnalysis/Candlesticks/EveningStar.html)
Overall, I find that trading patterns give you an idea of future movements. The chart patterns give you the range and bound, but also predictions on future price movement. Lastly, the patterns just give a definite confirmation.
Trade wisely, Trade responsibly.
