It is popular opinion sometimes that a trading strategy might no longer be effective if one begins to loose money while trading instead of gaining.
An important question i ask myself whenever i hear about people complaining or simply discussing a series of consecutive looses they have made while trading using a certain strategy is;
HOW MANY CONSECUTIVE LOOSES IN TRADING CAN YOU HANDLE BEFORE YOU ACCEPT THAT YOUR CURRENT TRADING STRATEGY IS BECOMING LESS EFFECTIVE?
Usually 3 in a row I stop that certain strategy and change it. Sometimes a certain strategy will not work even it is fit to the current situation, why? Because the market is volatile there are some instances that the market didn't go along with your prediction and will happen the unexpected. Good luck to your trades there's a lot of effective strategy out there that works on bearish and bullish market.
