Yes, not always the strategy used for trading is effective. Market conditions are constantly being updated from time to time and we have to re-study them. it takes skill and emotional stability in dealing with the market, many traders lose money because they do not re-learn market conditions and change trading strategies. every time we enter into a trade we have to really understand the state of the market and decide to trade if we already have a good analysis.
Sticking with one method of on how you do trade wouldnt really be that effective even if you do make out several methods or strategies but still it wont really make out an assurance of higher efficacy of your analysis.
This is where do lots of trial and error involved with trading which you would be finding ways on how to utilize your steps for you to take
advantage towards the market.
Yes, it might not give out best or assured results but at least you do know on what you are doing.
