You must become totally focused on trading well as opposed to making money. You must learn from someone who can show you how to trade successfully rather than rely on machines and promises of “golden eggs”. You must become absolutely disciplined in the activity of trading. |

Some quick points, to be making money, Profit Factor must be greater than 1.
- Profit Factor (PF)
- = Gross Gains / Gross Losses
- = (Average win * number of wins) / (Average loss * number of losses)
- = R * w / (1-w)
- where R = Average win / Average loss
- w = win rate, i.e. % number of winners compared to total number of trades
Re-arranging, we have
- w = PF / (PF + R)
- R = PF * (1 – w) / w
Sample numbers showing the minimum R required to break-even (i.e. PF = 1, assuming no transaction costs) for varying win rates.
- w = 90% >> R = 0.11
- w = 80% >> R = 0.25
- w = 70% >> R = 0.43
- w = 60% >> R = 0.67
- w = 50% >> R = 1
- w = 40% >> R = 1.5
- w = 30% >> R = 2.33
- w = 20% >> R = 4
- w = 10% >> R = 9
The style of trading strongly influences the win rate and R (average winner / average loser). For example, (more…)
