SHOP Go Long! Will it break out this time?

Recently SHOP has retraced and held the 50% Fib level and has been trading within a channel where it is about at the mid point of it. The King Trading Momentum Strategy yesterday issued a buy signal. This strategy combines the 5 EMA crossing above the 13 EMA, RSI strength, favorable momentum as measured by ADX plus evaluating recent volume changes. It has been forming a bull flag on the hourly and pre-market suggests this may be ready to break out. I followed the signal and bought a half position, looking to protect the trade at take-profit of 4%. During backtest this proved to be an optimum area and a stop-loss of 3% is warranted. SHOP and over 100 equities are built into this script. If trade protects at 4%, a trailing stop-loss of 2% will be adhered to in order to lock in as much profit as possible if this stock breaks out of the descending channel! I'm thinking its not too late for me to add to this position given typical morning volatility.
