I guess Coral is saying that there is no evidence (at least on this forum) that it works, or doesn't work, no evidence either way.
The entries sound very similar to the Turtle system, which has been proven to work.

Personally I suspect it does work, recently I coded a simple pattern-:buy if 1)Today's close is greater than the close 30 days ago to indicate some sort of trend, And 2) Today's close must be lower than the close 9 days ago (indicating some sort of pull back. If those conditions exist then buy on tomorrow's open. The pattern produced 354 trades, with 57% accuracy and an average profit of $421 a trade.

It seems to me that the simple patterns seem to work the best. So I am curious to see how the 7-10 holds up under computer testing.
