What do you do to a trading strategy that already earns you a good percentage in profit. do you still try improving on it to ensure it does not fail? or do you let it be until it starts showing signs of failure?
Enjoy it while it lasts because trading strategies don't last forever, and after some time, they might not yield the same results as they used to. It is important for a trader to be ready for a new trading strategy when a current strategy is not providing the same results. It is impossible to keep trying to improve a strategy that is failing because trading strategies are not static; the market doesn't remain the same forever. Relying on a particular trading strategy has really been one of the problems faced by some traders.
