Years ago I purchased the turtle system from Russell Sands who was the first to leave the Turtles (a recorded version of his lectures) .It never worked for me .It also stopped working for Russell for he decided to become a lawyer( I don't know what happen with this pursuit) . A few years later he contacted me with a new scheme looking for investors to join him with others to to invest in his card counting system..in Vegas and other casinos
What a hoot

Sure - I dont think this or any mechanical system will work all the time. If the markets were that easy... That doesnt mean that it will never work again.
What I mean is there could well be year after year where the markets arent trending - or not enough of them to cover the losses from the false starts. CTA performance hasnt been great these last few years.
It would be interesting to see for example if the method would have kept you in the CL decline.
On a side note, an acquaintance of mine works for one of the lager CTA's. He said only around 2-3 out of 10 trades make money on their main fund.
