Winning trade: I will hold a winning position as long as possible. I dont trade with a T/P, but I make certain risk management adjustments at predetermined levels in the event price moves in my favor. I let the market take me out via a violation of a strong s/r level or I will wait for price action that gives a strong indication of a reversal before a s/r violation. I prefer the prior
Winning trades are difficult to manage because there is a combination of trying to let a position run, adding to a positon, moving your s/l while allowing space for a drawdown, etc, that can be tricky. And your doing this while keeping risk management a priority.
Losing trade: I employ a S/L every time and will consider closing a trade out early if price is at a certain % of the way to my S/L in relation to my entry. Its much easier for me to manage a losing trade becasue a S/L removes certain variables from the equation. I also have a quicker trigger w a losing position because I put more importance on minimizing risk than maximizing potential profit. To me, minimizing risk is the best way to maxamize profit
