Benjamin Formula

Named after Benjamin Franklin, the Benjamin Formula is a mathematical method for evaluating a trade setup. It was named this partly because you can set a goal for yourself to make $100 per day or $100 per trade, and Benjamin Franklin is on the US 100 dollar bill. It was also named this because Benjamin Franklin was both scientifically and financially savvy with a lot of advice that still rings true today.

The first part of the formula basically says "Is this trade worth taking?" You look at the potential target after entry, and determine whether the risk to reward ratio meets your standards, and whether the potential profit meets your income goals. We'll prequalify the trade by making sure the following is true:

|E-S| < 2|T-E| and |T-E|L > 100

where

  • E = Entry (in points)
  • S = Stop Loss (in points)
  • T = Target (in points)
  • L = Lots (in standard contracts, determined by the formula below)

In this example, you first determine whether the trade is worth taking by seeing whether it has a 2:1 reward to risk ratio. Then you determine whether it meets your goal of making $100 per trade. The ratio you aim for and per-trade goal are variable depending on your personal system. If the trade doesn't meet these prequalifications because it's moved too far, we simply move on and don't take the trade. This is the formula to determine roughly how much we should put on the trade:

L = (.02A)/|E-S|

where

  • E = Entry (in points)
  • S = Stop Loss (in points)
  • A = Account Balance (in dollars)

Using this formula, you will risk 2% of your account size on the trade. To risk 1%, change the .02 to .01 or any other amount that is correct for your system.
