In this example I show the pattern of the end of a downtrend which has the following conditions: 1- long and strong downtrend. 2- A stretch in volume which is one sign for the end of the trend (sell panic). So, whales are ready to buy at low prices. 3- A falling wedge. This means there are lower lows but with weaker momentum, this means whales started to buy. 4- Buy after a reversal candle.
