  • POP helps decide if likelihood of profit worth capital investment
  • POP doesn't tell about profitability throughout duration
  • POP doesn't indicate expected value of trade
1:35lesson

POP calculation methods and limitations

  • POP can be estimated using delta for approximation
  • Many platforms use simulated outcomes to calculate POP
  • Models assume smooth continuous price movements
  • POP is poor measure for binary events like earnings
3:23lesson

POP vs. actual profitability

  • Theoretical POP around 68% vs. realized 78-79%
  • Only 17-25% of trades profitable throughout duration
  • POP tells about expiration outcome, not full duration
  • Small losses more likely to recover than large ones
5:04lesson

POP and expected value

  • POP doesn't tell expected value of trade
  • Same theoretical POP can have different realized outcomes
  • POP tells about single trade outcome, not repeated trades
  • Use historical stats like average win/loss for better insights
6:49lesson

Using POP effectively

  • POP helps understand risk-reward for multi-legged strategies
  • POP can show you collect small credit vs. tail risk
  • POP informs decision-making for single trade outcomes
  • Combine POP with historical data for better strategy evaluation

P50 and POP comparison

  • P50 shows probability of reaching 50% profit
