For the question of which is the best strategy, the answer must be aimed at a new trader who is not yet profitable. Everyone else already has a working profitable strategy and very few will be wishing to dump a good strategy for one they're not familiar with.
So for a new trader, what are the characteristics of a suitable strategy?
- simple to learn
- has clear understandable rules
- responds appropriately to unsuitable market conditions
- gives clear instructions to the trader on what to do at each point
- uses objective chart features
- adequately manages capital risk
For me also, a win rate better than 50%.
A nice bonus feature would be if the strategy can respond to unusually positive market conditions to allow extra profits to be generated.
