A major concept we teach is "stacking the edge". An edge is defined by a greater probability of something happening over another. In this case, because of all of the Content and Context on the USD/JPY chart at the time of entry, we felt that we had a greater probability that price was going to go lower than continue to go higher.
This is the only job as a "trader" is to find price edges that we can exploit.
Watch for a great live example here of "Stacking The Edge".
We blog about trading, emotions, risk, reward, the struggles, the successes and just anything we think is fun and want to share with the BTG Community.
