There is a triangle in BMFBOVESPA:ECOR3 5M that could lead to a upward trend or a downward if breaks below line.
Also you need take care about false breakings in this pattern, for now i just can suggest watch market movements and wait a trustful breaking.
If you wanna hold this share (Swing trade) there is a good trending line on H4, so keep long position until...
This chart shows a morning star (uptrend chart pattern) ongoing on GOLD. TF is H4.
I would recomend long position with SL below daily minimum and TP on 1300.00, if you wanna less risk you should move your SL to the minimum of last closed candle.
