What are common mistakes when trading a descending triangle?

The most common mistakes when trading a descending triangle are entering before the breakdown confirms, ignoring volume, mistaking it for a falling wedge, and trading against the broader trend. Shorting too early, before price decisively closes below the flat support, exposes you to failed breakdowns where price bounces hard and runs your stop. A breakout without a volume spike is usually a fakeout, so demand expanding volume on the breach. Confusing a flat-support descending triangle with a downward-sloping falling wedge flips your bias entirely. Skipping a defined stop above the descending resistance line is what turns a manageable loss into account damage.
