Here is the link to Declan's review of The Odds Maker (with lots of good screen shots).
Declan asked us 2 questions and we responded. Here's our answer:
Let’s answer your first question about net winnings in The Odds Maker. The answer comes from our guidebook - [here is the relevant section:]
4.5 Net winnings: $62.45
Net winnings looks at the total amount of money made using this strategy. If the result is positive, then money was made. If the result is negative then money was lost. This measure is another that does not take the profit target into account. Winning is, quite simply, the difference between the entry price and the exit price.
Multiply the average lot size in trades by the net winnings to estimate a strategy’s hypothetical return minus any assumptions regarding commissions or slippage. In this case, if 1 share of each stock in the strategy were bought, $62.45 would have been made. Of course, if 1,000 shares of each stock had been purchased, $62,450 would have been made. This result looks different if percent, instead of dollars, is selected for the profit target. In that case the result would say something like
“Net winnings = 162.5939%”. In this case if $100 worth of each stock in the strategy were bought, $162.59 in profit would have been made. Of course, if $10,000 dollars worth of each stock had been purchased, $16,259.39 in profit would have been made.
The answer to your second question is a good one. We think there enough data points to evaluate strategies. Here’s why. First, remember that The Odds Maker looks at the entire market – unlike other backtesters who evaluate one stock. If this were the case with The Odds Maker we would have gone back much further in time. When you see the results look at the denominator that tells you the number of trades evaluated. This number can go into the 900s, 1000s. Over a 2 to 3
week time frame that’s almost too many trades for a human to make per day.
Second the 2-3 week timeframe puts more of an emphasis on the recent moves
of the market to highlight whats working now. Given these 2 points we think The Odds Maker certainly analyzes a lot of data to arrive at timely, relevant guidance in crafting a strategy that’s most in tune with the market.
Let me know if this explanation makes sense or not. Thank you for the blog mention and the Forbes information.
