Money Management
Money management determines the success or failure of any system.
Win rate has little to do with success. You don't know your win rate until you actually start trading any system so you must have bullet proof money management starting with the first trade. Actual trading will always be different than any exercise in backtesting.
Once you start trading a system you can track the win rate but more importantly you should track your return on investment (ROI) for each trade. Making more than you risk on each trade is a path to success. Such a path can be successful even with a low win rate. Consistently accepting trades that return less than what you risk is a path to failure.
Ask yourself the following questions:
How will you determine your profit target?
How much will you risk on each trade?
Will you be able to exit the trade according to your predetermined stop loss?
How much can you afford to risk on any given trade given your available funds?
Will your account survive if you lose 10 trades in a row based on what you think you can risk on each trade?
Do you have the mindset that it's ok to blow accounts searching for the right system? If you do...stop trading and pick your favorite casino gambling game.
