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?
Trading is a risk management that you may be able to control easily but before that you need to be knowledgeable enough and have previous experience. Without experience you can never expect anything better from trading.
