Hi folks; When we are seeing 4H time-frame,it obvious that price moves on a downtrend channel so after a breakout and retest it can pushes the price up till touch the upper downtrend line what's more; it made a double bottom classic pattern but it has not approved buy neckline and breakout so we ought to keep in touch with chart and candlestick.After breaking out the neckline and retest,we can enter to long position till T.P1 & T.P2.
