Once you start shorting or going long, your cost price is irrelevant to any subsequent actions because whether you sell or not depends on market trends, and has nothing to do with whether you are currently still profitable. If the pattern is good, continue to hold; if the pattern is bad, reduce your position or even liquidate.
