First of all, you can see the head and shoulders pattern (orange). This formation cancelled the upswing and started the current down trend. After breakout of the neckline, the price went significantly lower, creating in the meantime the pennant formation (red). Pennant is a trend continuation pattern so no surprise that the price went lower.
Currently, we are locked in the similar formation but in this case, this is a triangle pattern (black lines), as the formation is much bigger. The difference is that this pattern can result in a breakout of the lower and upper line so now it is not the best time to trade.
