Do not buy it.
It is based on hypothetical results it is in the past, market has changed. System is over optimized for sales purposes. You might have to wait a decade until system will perform well again and you need to know when it performs well. Take a look in journal section on "Tri Pak's ES swing system" it makes money today but it didn't a year ago, and it probably will not in a near future.

Anyone tried this from tradingmarkets.com - claims an 88% win rate?
Feedback appreciated - if anyone wants to split the cost, PM me.

88% perhaps but what is not said is that it is a rather a CONDITIONIAL PROBABILITY noted traditionally P(A | B) (probability of A knowing B) where B is the market context or global trend that is to say one must know before if the market is globally bullish or Bearish; let's remark that it could also be sideways but let's simplify for the demo then P(B)=1/2.
What we really need to know is P(A) and not only P(A | B).
Thanks to Bayes Axiom on conditional probability we know that:
p(A and B) = p(B) * p(A/B) (also = p(A) * p(B/A) but not used)
so that p(A) = 0.5 * 0.88 = 0.44 = 44% is an estimation of the real probability of this system![]()
88% perhaps but what is not said is that it is a rather a CONDITIONIAL PROBABILITY noted traditionally P(A | B) (probability of A knowing B) where B is the market context or global trend that is to say one must know before if the market is globally bullish or Bearish; let's remark that it could also be sideways but let's simplify for the demo then I will suppose that P(B)=1/2 since I don't have any other knowledge on the design of the system.
