You can see that we are nearing a resistance (red horizontal line), and if ADA gets rejected there, that could very likely cause a downfall from the flag.
The target for the flag is around 2,500 satoshis, but since the 2,700 satoshi level acted as a strong support before, I will assume as target the whole range between 2,500 - 2,700 satoshis. That is where I will probably place some buy orders.
Make sure to only sell/short if we have a breakdown from the flag (with high volume).
Flags are considered to be amongst the most reliable patterns. As you can see here, nothing is 100% reliable, and there's no guarantee for anything. You shouldn't listen to anyone, who tells you otherwise.
Let's see if we are right :)
