My thoughts do not agree with you.
So, what is a bad indicator in your thinking. Give me the worst indicator you think and I shall show you how to generat profit from it.
Again it is not the indicator who makes profit, it is you, if indicator is giving 60% profit then it is your money management to convert your losses into profit, the indicator is not at fault.
See the indicator follows the market, the market does not follow the indicator, so only the probability theory works here.
If you want to succeed, stick to one indicator, one currency pair and one time frame, use martingale and then see your results
Hope this helps
