Following are the formulas for the calculation of some of the efficiency performance graphs.

Assume the following:

- Enter long at price of 100

- Market moves down to a price of 90

- Market moves up to a price of 130

- Exit at a price of 110

Entry efficiency is calculated as:

(maximum price seen -  entry price) / (maximum price seen - minimum price seen)

= (130 - 100) / (130 - 90)

= 75%

= The entry took 75% of the trade range

Exit efficiency is calculated as:

(exit price -  minimum price seen) / (maximum price seen - minimum price seen)

= (110 - 90) / (130 - 90)

= 50%

= The exit took 50% of the available trade range

Total efficiency is calculated as:

(exit price -  entry price) / (maximum price seen - minimum price seen)

= (110 - 100) / (130 - 90)

= 25%

= The trade represented only 25% of the trade range

• The formulas are reversed for short
• The blue line on any efficiency graph represents the average
