We can use the advanced patterns for various purposes, in this case, patterns, gives us good entries in its conclusion (counter-trend), but can also provide us eventual sell zones (in favor of the trend) - the corrections.
Now, we also know everything will depend on the power of corrections, and for that we lower the time frame to monitor price action at these times. Stronger trends, lower corrections and vice-versa.
So, we buy at patterns conclusion (check oversold conditions and divergence) expecting lower degree corrections (the 38%<>50%) to sell after it and take the train.
Note this is a typical IF=THEN trade setup, it can become tricky to trade this. The main idea is to get inside the trend as soon as possible without suffering unnecessarily. Try to keep an eye on lower time frames divergence and obviously the printed structure.
