Even though price is at resistance of triangle and a sell may be the most logical option, in the grander scheme of things, this symmetrical triangle suggests a continuation of the preceding uptrend. A breakout above this triangle would then be the cue to go for long positions. However, pending a breakout, still consider a selling position for the short term. Selling at this resistance area after further confirmations provides a better and safer place to enter but keep the possible triangle break at the back of your mind. Cheers!
