When strategies are well constructed 

I'm saying even good strategies need to be well constructed having optimized parameters, settings & filters. Once those requirements have been completed the strategy needs to be extensive backtesting, forward testing, & paper traded over a variety of market conditions to establish its profitability. When you have a robust strategy the issue is most likely attributed to "behavioral mistakes" & or "market changes". Remember, the forces that change the markets are the emotions of the participants driven by events.

When developing a trading strategy

Some of the most difficult considerations that will affect profitability are when to take profits & when to cut losers. Get one or both of these conditions wrong & you are doomed to fail as a system trader. One of the most common mistakes traders make is the inability to correctly detect & define price trends, the very heart of trading.
